Re: AJs 72 Pavement Pounder build
Man that does really suck, but on the bright side, better to find it now rather than after you put it all back together, repainted, fuel injected, etc...then it blows up. ;)

Re: AJs 72 Pavement Pounder build
AJ, do all smc's have that thrust washer behind the cam sprocket? I don't clearly remember taking one off when I did my timing chain
|
Re: AJs 72 Pavement Pounder build
Uh, I dunno. This build will be a learning process for me as far as engines go. I've never dug this far into one before. At this point, I'm taking guidance from my engine builder friend.

Re: AJs 72 Pavement Pounder build
UPDATE 06/07/09: Getting back in the game.
I've been quietly searching for an engine to build to replace the purple 454. I found a smokin deal on racingjunk for everything to build the engine except the heads. Picked it all up today. http://www.texas4x4.org/gallery/albu.../454_parts.jpg Here's the basics: BBC 454 bored 30 over Flat top pistons Erson Cam (288 duration, 492 lift) I've decided on a set of Edelbrock Performer or Performer RPM aluminum heads. 110cc chamber. This will put the compression right at 9.5:1. Now I just need to find a good set. Time to start building... |
Re: AJs 72 Pavement Pounder build
Nice new parts!

Re: AJs 72 Pavement Pounder build
UPDATE 8/28/09: Time to get to work. Works been keeping me super busy lately and the K5 has been neglected. I made a slight direction change on the engine after finally unloading all of the old engine and miscellaneous parts I had laying around. I just placed the "big order" with Summit today. Here's the final specs I'm going with:
Block: GM 2 bolt BBC 454 bore .030 over Rotating assembly: GM cast crank, Speedpro flat top pistons (3cc eyebrows) Cam: Comp Hydraulic Roller... yes a roller! (CL11-412-8.... advertised duration 266 In/276 Ex, lift 485 In/485 Ex, lobe sep 112*), Comp roller lifters (included in the comp kit), Comp adjustable timing chain (cam timing adjustable to 1/4*) Heads: Edelbrock Performer High Compression aluminum cylinder heads...100cc semi-open combustion chamber Induction: Edelbrock Proflo MPFI fuel injection kit With the flattops and the heads, compression should work out to just about 10:1. I bumped up compression a bit since I'll be running aluminum heads. If CamQuest 6 is at all accurate, I should end up with this: http://www.texas4x4.org/gallery/albu...uest.sized.jpg Big pic can be seen --> here Already made a date with my engine builder friend to start on the bottom end of the engine next weekend....FINALLY! |
Re: AJs 72 Pavement Pounder build
Aw man yer gonna love that 454 power :metal:
Mine is about 450HP 550tq @ 9:2 comp :chevy: Sooo much fun!!!! :mm: |
Re: AJs 72 Pavement Pounder build
Thanks Burt. I'll have a ton of questions for you when it's time to run everything for the fuel injection.
|
Re: AJs 72 Pavement Pounder build
I hope I can help, once you get it running take your rig to a Dyno. They can tune your air/fuel mix so NOT to burn up your investment. The Lean & Rich gauge is just a Green & Red LED and I had mine way too lean and the dyno guy said if ran like that in time it would burn up..
So thats my advice on getting the FI tuned. I have all my Pro-Flo settings writen down so if you eveer need um I got um :metal: |
Re: AJs 72 Pavement Pounder build
Your settings may be a good starting point, but yeah, was gonna have the smart guys help tune it. I was talking more along the lines of where/how to run the fuel return line, etc.

Re: AJs 72 Pavement Pounder build
Cool man, I'll be here :uhmk:
:mm::chevy::mm: |
Re: AJs 72 Pavement Pounder build
Stayed home from work today because I wasn't feeling good....until Mr. Brown showed up with my new heads, a few sets of ARP bolts, and the new brake prop valve.
http://www.texas4x4.org/gallery/albu...3889.sized.jpg My wife told me to "get my Christmas morning on". So, I had to open one of them up. http://www.texas4x4.org/gallery/albu...3887.sized.jpg |

Yeah, I had the title changed. The more I thought about it lately, the more that "pavement pounder" implied mall crawler to me. Can't have that now, can we? |
Re: AJ's '72 Cruiser Crawler Build
dude, love the parts and the direction of the build. good luck.

Re: AJ's '72 Cruiser Crawler Build
Great build man. Looking forward to seeing the finished product.

Re: AJ's '72 Cruiser Crawler Build
UPDATE 09/07/09 - Engine building: Labor day, and man, I labored. I learned a ton from my engine builder buddy....he made sure to point out all the different ways things can get jacked up as we went. My brain definately feels heavier now. We completed the long block today.
The first hour or so of the day was cleaning and prepping parts. Here's the rotating assembly all laid out on the bench. http://www.texas4x4.org/gallery/albu...0034.sized.jpg Clean block with the main studs installed http://www.texas4x4.org/gallery/albu...0035.sized.jpg Main caps, main bearings, and crank installed http://www.texas4x4.org/gallery/albu...0037.sized.jpg Fitting rings and putting in rod bearings http://www.texas4x4.org/gallery/albu...0038.sized.jpg Pistons installed. Rotating assembly and short block complete. Tightening down the oil pump. http://www.texas4x4.org/gallery/albu...0039.sized.jpg Edelbrock heads installed and torqued down....long block complete. The intake is just sitting there to keep the engine closed up. Same applies to the pan and timing cover http://www.texas4x4.org/gallery/albu...0041.sized.jpg Wrapped up until next weekend http://www.texas4x4.org/gallery/albu...0042.sized.jpg I'm definately happy with what we got done today. Once the cam and lifter set comes in, we'll put the cam in and degree it. Then put on the intake, and button up the timing cover and oil pan. |
Re: AJ's '72 Cruiser Crawler Build
Drool! :chevy:
There's absolutely nothing like building your own motor! :metal: How much more HP do you think you'll have over the last one? |
Re: AJ's '72 Cruiser Crawler Build
The last one couldn't even chirp the tires. It had too many internal issues. According to CamQuest, this one should make 520HP @ 5000 and 580TQ @ 4000. It's obviously gonna be a much better built motor....cuz I did it :metal:

Re: AJ's '72 Cruiser Crawler Build
Hold on Hold on! Drapes in a man space window?? Man o man, I know your wife made you doit right! :uhmk:
heheheh Just messin :metal: Thanks for sharing! I'm lovin it! :mm::chevy::mm: |
Re: AJ's '72 Cruiser Crawler Build
Time out!!!! That's my buddy's man space. In pic #2, those are all motorcycle engines on the shelf....and under the table...that's what's left of the blown nitro engine for his top fuel drag bike.

Re: AJ's '72 Cruiser Crawler Build
hahaha well tell him they look nice ;)
Coffee drivin harrasment I suppose :mm: Keep us posted :metal: |
Re: AJ's '72 Cruiser Crawler Build
No progress these past two weeks. Work had me traveling the past week. Pretty much as soon as I got back, I left for the weekend to go dove hunting...Dad and I did pretty well considering the drought in South Texas this summer.
Cam and hydraulic roller lifters arrived this week. I'm hoping to get them in the engine and button up the engine next weekend. http://www.texas4x4.org/gallery/albu...3899.sized.jpg http://www.texas4x4.org/gallery/albu...3902.sized.jpg I still need headers and am on the fence as to what to do about my gas tank....more to come. |
Re: AJ's '72 Cruiser Crawler Build
Yummy! very close to the Comp cam I used, I didn't go roller though. Sometimes I wonder what the difference would be on that? I drove my K5 around the 'hood' this weekend. Fun stuff thease 454s :metal:
Good Times even if I am just picking up dinner hahaha :mm::chevy::mm: |

Re: AJ's '72 Cruiser Crawler Build
That motor's lookin real good!
|
Re: AJ's '72 Cruiser Crawler Build
UPDATE 9/27/09: Bottom end complete. Put the new cam in today. Degreed it with the new timing chain, which is cool btw because the timing is spot on with the grind sheet. The cam ended up advanced 3*. Dropped in the new lifters, and closed up the bottom end. Oil pan is bolted down as is the timing cover. We woulda finished the motor, but my friend forgot the adjustable pushrod to measure with...so no pushrods yet. Loaded it up on a trailer and took it back to the shop.
The adjustable timing chain. It's also got a bearing built into the back side so's it won't eat up the block like the last one did http://www.texas4x4.org/gallery/albu...0050.sized.jpg Roller lifters. SEXY! http://www.texas4x4.org/gallery/albu...0051.sized.jpg This was supposed to be the picture of the engine loaded up on the trailer to head back to the shop...but I forgot. So, imagine it looking just like this, but with a motor on a stand and strapped down. http://www.texas4x4.org/gallery/albu...0052.sized.jpg |
Re: AJ's '72 Cruiser Crawler Build
I can see it now.

Re: AJ's '72 Cruiser Crawler Build
You must have painted it camo
|
Re: AJ's '72 Cruiser Crawler Build
Sweet progress!

Re: AJ's '72 Cruiser Crawler Build
Nice updates AJ but there's one thing I noticed. I think the computer program you inputed your data into may be a little bit off. It seems to me you're trying to go for a bit of a hotrod and I think you would of benefited from a larger cam. The one you've chosen is just a step above stock, an RV cam if you will. The heads and intake combo you have is great and all but I don't think you'll really be reaping the benefits of them with that cam. You will make good torque (~400tq) but I think the hp will be lacking and not quite what you're looking for (~325HP OR SO). I'm not an expert by any means but I worked at a machine shop several years ago for a while and i've had my hands on quite a few other engine builds so I do have an idea. I really like the Comp Cams Extreme Energy series and I think if you go went with one of those cams you would get some of the performance I think you're after. The only reason i'm making this suggestion is because I don't want you to get this thing together and installed and realize you shoulda gone bigger. Hope you don't feel i'm stepping on your toes, just trying to offer some pointers.

Re: AJ's '72 Cruiser Crawler Build
520hp and 580tq? What compression are you running with the EFI? Are you going to get it dynoed in SA when you are finished?
