71 4x4 BBC Swap: Doing what I should have done the first time!
Ok for those that don't know I burned up my TH350 Christmas Day on the way home from spending time with my family. So, I decided to upgrade to a a TH400 and find a divorced 205. Well I found all that for about $350. Then I made a newbe mistake of making a crossmember for the trans and not mocking up the tranfercase. So the drive angle was off. I decided to install a body lift and move the motor forward 2". So one thing led to another and what use to be just a blown tranny turned in BBC swap, new trans and new t-case. Ok so I ordered a 3" body lift from performance accessories and started installing the kit and found out the bolts are all wrong. I believe that 6 out of 14 are correct. So I will be calling Performance Access. tech support on monday to see if they will send me the right bolts.
So my biggest problem is that I need to buy a 454 BBC asap. I have three ideas for a engine crossmember: 1. ORD, 2. DIY4x, and 3. build my own. Other than firewall issues, is there anything else that need to be done in order to fit a BBC in my 71 4x4? http://img.photobucket.com/albums/v6...n/P2280133.jpg http://img.photobucket.com/albums/v6...n/P2280134.jpg http://img.photobucket.com/albums/v6...n/P2280135.jpg http://img.photobucket.com/albums/v6...n/P2280136.jpg http://img.photobucket.com/albums/v6...n/P2280137.jpg http://img.photobucket.com/albums/v6...n/P1300058.jpg http://img.photobucket.com/albums/v6...n/P1310064.jpg |

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
4core rad should be used, you are doing the right thing! :metal:
I LOVE driving my 454 :chevy: http://www.norcalbigdawgs.net/Galler...uo05/bbcin.jpg http://www.norcalbigdawgs.net/Galler...buo05/bbc3.jpg Being on a build budjet helps but there are alot of cool parts to buy out there :metal: Good Luck! Do it slow and doit right then GET IT DIRTY!!!!!!!!!!!!!! :burnout: :mm: |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
:agree: this is the right thing to do. if the wife starts questioning you just tell her that there were some serious problems and to make it easier you took the engine out then you realized that it was going to need a rebuild so you bought another motor because it'd be cheaper than a rebuild.

That is what I told her..I was originally going to rebulid my 350..then I found a running when pulled 454 for 175bucks. I told her it would be cheeper to replace the engine..she doens't know what a 350 or a 454 are :lol: It took a year or so collecting parts and getting the longblock assymbled. :metal::chevy: she has no clue what i ended up spending over that year :uhmk: |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
So I bought a 454 from the same buddy that had the Turbo 400. Ya'll better sit down for this one... $50!!!:jdp: The number one piston spun a bearing, over than that it is complete from intake to oil pan. It doesn't have pullies, but for 50 bucks who cares! I'll be posting pics of it this weekend (hopefully) after i clean the garage and what not. I am going for a 50/50 match up with HP and TQ. Let me know what you all think. I am building a mud truck that is still used on the street. So i'm looking for the best combo to get most of it with out getting 2 MPG or less. More info to come.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
Buy your build parts for RPM range= Idel-5000.
454 is a GREAT stump pulling engine! Save your beer cans and get Fuel Injection :metal: If you build for lowend and continuous duty your truck will love it! :chevy: :mm: |

try this link. I moved my engine mounts, t-case,crossmember forward 1" for clearance. Stock valve covers helps too. make sure u add your build to the tread when you have your truck together. |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
Ok so I picked up the 454 yesterday. The only thing I know about the motor is that it came out of a 80s subur and the #1 piston has a spun bearing. Here is how is looks...
http://img.photobucket.com/albums/v6...n/P3040010.jpg http://img.photobucket.com/albums/v6...n/P3040012.jpg I'm looking to build a strong responsive motor. So I'm going to building for response at 1500 to 5000RPM. I'm looking at boring out the motor .030. For a cam I've picked out the Voodoo LUN-69202LK 1400-550RPM and Edelbrock RPM Air-gap intake. I going to run flat or small dome pistons to keep the compression up, MSD HEI Distributor, Holley Street Adventure 670CFM carb, and summit headers. I'm still thinking about roller rockers and cog belt setup. Open to advise and learn from ya'll. This is my first big block build and I don't ever want to build another engine for this truck again. So, I want to do it right and on the first time around! I'm doing my research and saving what little money I can. Here are a few more pic of the tear down. http://img.photobucket.com/albums/v6...n/P3040018.jpg http://img.photobucket.com/albums/v6...n/P3040023.jpg http://img.photobucket.com/albums/v6...n/P3040028.jpg http://img.photobucket.com/albums/v6...n/P3040030.jpg http://img.photobucket.com/albums/v6...n/P3040032.jpg http://img.photobucket.com/albums/v6...n/P3040039.jpg http://img.photobucket.com/albums/v6...n/P3040041.jpg |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
congrats on your find. your choice to build a low end grunter is wise. do you have a machinist picked out? hope the crank cleans up. a roller cam would be a wise investment. enjoy the build. -steve

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
SWEET!
So what is the number on your heads? Hopefully it reads 336781 :uhmk: or its cusin ending in 041 I think, don't remember the second number that is large port. Two common types small port and large port...I'm no gearhead so I don't know alot about it..This is my first 454 too so I am still learning: http://www.norcalbigdawgs.net/Galler...5/P1010003.jpg One thing to think about would be not useing HEI Dist, firewall clearance is tight back there..I have seen HEI work so it does fit...just tighter. I ended up building from idel to 5K so the cam I used is a bit mild. I ended up with CompCam Xtreme 4x4 family(RV cam really) 11-231-3. I wanted my engine to run all day and last a life time so I had the block decked, heads shave and stuffed w/over sized valves. 2.19In and 1.88Ex. My entire rotaing assy is balance too...sucker purrrrrssss! Then Sh**ts and Gets! the EFI helps alot with that..ZERO hesitation :metal: Talking about makes me wanna leave work and DRIVE IT!!!!!!:metal::chevy: hahah Ok too much :mm: for me today! hahhaaha |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
hei works fine IF u get u get a after market small cap. i got the mallory and LOVE it. i get 12mpg on the freeway converted to vac advance:metal:

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
I have a MSD HEI from my old motor and am planning on moving the motor forward for the clearance. For the heads next time I'm over at my brother's house I will look at the numbers.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
Dude, fully rollerize your engine. You will gain a little hp and a ton of longevity. Then w/proper maintenance this will be the last bbc you'll have to build. I had a 454 30 over built and totally rollerized and I am happy I did. Without sparkplugs in it I could turn the crank with one hand.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
I would go with a more conservative cam. Especially with those small port heads. If you are going to use tires that fit that lift then you are going to want low end grunt.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
ridin high is your truck a convert? Or did u do cross-over steering?

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
So what is this truck going to be used for?
Your current plan sounds more like a car engine than a 4x4. :uhmk: Holly is a great carb, just don't get bouncy(rutted fire road or sand dunes) or at any steep angles/hill climbs. That Holly will barf into your intake. Q-jet is the best carb for off-raod. I ran the Edelbrock 1901 for years on my 350. Don't get me worng the truck will be fun to drive for sure, just some sacrafices to think about, but again depends on what the truck will be used for. My .02c :mm: |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
[quote] What do you mean by a convert? I build my own custom cross over steering.
by convert i meant a 2wd changed to 4wd because the cross-over steering uses a 2wd steering box or something very similar someone said |

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
I go mud bogging out in madera

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
whats the mud like and how deep? last oct in hollister it was about 2-3feet deep and pretty slick seeing as it was clay. a lot of people got stuck unless they had boggers or when slow.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
Ok change of plans... I got with my buddy from AirFlow Performance and since I needed to by a new crank, He suggested that I build a 486 Stroker! My buddy has the specs and list of internals. I dropped the block off thursday at Fresno Performance to complete a deck, bore, balance, and clearance. I also found some bare large oval port heads, the 681 I believe, for $40. My buddy from Air Flow specializes in Port and Polishing heads. He is going to do a stage 2 port and polish. So thats where I at for now.
Anyone have a 1000cfm Demon carb? I need one. |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
Still waiting on my new crank, 4 week shipping, but everything else is ready to be picked up. So, while I am waiting I finished with the body lift, painted the engine bay and put the 39s back on. Take up too much space in the garage, plus I wanted to see what the spacing was with the BL. So here are some pics. I hate the bumper gaps. I will be fixing those later. Also I'm trying to pick a color for the block. I am thinking about a med silver gray. Let me know of any ideas you might have.
Before BL: http://img.photobucket.com/albums/v6...g/PC200312.jpg After BL and no drivetrain: http://img.photobucket.com/albums/v6...n/P4170055.jpg http://img.photobucket.com/albums/v6...n/P4170054.jpg http://img.photobucket.com/albums/v6...n/P4170053.jpg http://img.photobucket.com/albums/v6...n/P4170058.jpg http://img.photobucket.com/albums/v6...n/P4170059.jpg |
Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
I really really "liked" your truck because it look until i saw the gaps it still looks great just need to move the bumper mounts or something up. But i think the best idea would be to build a bumper because if you move the stock bumper you have the frame showing. i think you will find something to make the gaps not look asbad.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
I've really busy with work lately, but I did get some time to work on it this week. I was able to clean up the turbo 400 and paint it. I was also able to clean up the engine bay, frame, and wheel wells.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
Sorry for the delay in updates, I've been busy at work and saving up cash to buy parts. So this is where I'm at. I got the block back last week. Fresno Performance decked, bored, honed, line honed, and clearanced the block for the stroker setup. This last weekend I was able to get some paint on it. My first order from Summit Racing came in on Thursday and got a shipment from my buddy today. Another thing is while moving the truck around I broke my rag joint on my steering shaft. I was able to find a nice used one, and broke that one first try. So I call around, did some searching, and found a really great price for a heavy duty steering setup from Borgesen. I ordered a 24" telescoping shaft and two HD U-Joints for just over $200. I also ordered my DIY4X Cross member. I'll be getting that in the next week or so. Currently I have a bare 489ci BBC Stroker Block that is waiting for innereds. I have H Beam Connecting Rods, Keith Black Pistons, Edlebrock Air Gap Intake, MSD HEI Distributor, and Doug Throley Header. I'll be ordering the rest of the internals next week. For now here are the pics of my progress.

Re: 71 4x4 BBC Swap: Doing what I should have done the first time!
how much is this 489 setting you back if you don't mind? And from my understanding correct me if im wrong but a 489 stroker is a standard 454 blck with different internals.
