bulkin'up73chevy · 02-05-2004, 09:20 PM

Anyone have a pic of what a 73 chevy cheyenne super 10 would look like dropped. If not on some nice tires and what I could do to the engine to get better performance out of it. I'm thinking:
Performance cam. Don't know what kind
Dual intake Manifold Edelbrock
Dual Carbs Edelbrock
Really hot spark ?? How do I do that??
10:1 compression pistons
Performance heads and headers Edelbrock
and some 3"pipes with flowmasters is what I think I might to?
Any info would be gratefully appreciated. Will I blow my engine doing this????

Russell · 02-05-2004, 09:47 PM

a) 3" Is entirely too big for dual, you do need some backpressure

b)Take a look at the comp cams, they are what I am buying eventually

c) dual carbs is more trouble than it is worth in my opinion

d) with 10:1 compression you'll have to run 92 octane, regardless...

e) performance heads are a good idea

Just my opinion, I'm not a avid engine builder yet though, so someone may dissagree with me...

bulkin'up73chevy · 02-05-2004, 10:30 PM

Thanks for the reply i'm running 2.5 duals already I think haven't measured them quite yet. Is that good enough.

*1FaastC10* · 02-05-2004, 10:33 PM

Russell, 10:1 can be done on 87 octane if its cammed right.

bulkin'up, what are you looking to do with this truck? if its just going to be a fun driver, i'd go with something along the lines of a Comp XE 268, 9.6:1 compression, backed with a 3.73 gear. performance heads are a must!

TIMSPEED · 02-05-2004, 10:34 PM

1.) Look at my sticky Suspension topic. Go with the 5/7 drop, get some shorty headers
2.) Have your current small block (I'm guessing) rebuilt using a kit from PAW, which is only $500 for parts. (Good Quality parts)
3.) Get the Vortec Upgrade Kit from Pace Performance for $800. (Consist's of Vortec Fast Burn Iron Heads, and a Matching Performer RPM intake)
4.) Get a Nice Holley 4160 750cfm 4bbl Carb
5.) I'd imagine you prolly already have a TH350 tranny, which you could get rebuilt with a shift kit
6.) Buy a set of 17"x9" rims and get 255/50's all around
7.) Get a Posi
8.) Nice Paint Job
9.) Go out and enjoy your DAMN FINE C10.

BTW: The engine I rattled off, is good for 400bhp

Post a pic of your rig and let someone photoshop it for you.....

and throw it in the trash. 750cfm is way too much for a 350, 600 or 650 should do just fine.

For a simple truck, that would be awesome! 20"+ billet wheels are a must though.

bulkin'up73chevy · 02-06-2004, 01:04 AM

It's not a c10 unless a cheyenne super suddenly changed descriptions that I don't know of. Thanks for the info guys anything else I should know cause i'm still thinking of what I can do. And I want to have it planned before I start on it. Then if I decide to change in the middle of my customizing I could do it. And to post a picture how do I do that? I would love to have it photoshopped if I could. Thanks guys again for all the info.

*1FaastC10* · 02-06-2004, 01:05 AM

Ken, do we not want to give the noobs practical advice that they can apply to their trucks and be happy with them rather than having a piece of crap that never runs right.

bulkin'up73chevy · 02-06-2004, 01:12 AM

Ya guys what he said hehe.

You obviously haven't seen CarCraft this month. They did a write-up on the 350 H.O. Motor, and they used the 750cfm Holley/RPM Air-Gap/healthy Cam and got 400bhp

I'm planning on going with a pair of 2.25 duals with an x-pipe and aerochambers coming from a set of ceramic coated Nova headers. I read somewhere that 2.5 is big enough for something like 400 hp or so...

Ok, cool, Thanks for correcting me

79BIG10 · 02-06-2004, 03:51 AM

Just a quick thought but how many miles are on this engine you are wanting to buil up? If it has alot of miles on it then you're not going to get the best potential out of it. Save your money and get a fresh engine and build it up like you want. But if it's a newer or low miles engine then go for it.

stepside454 · 02-06-2004, 12:08 PM

Timspeed, for dyno purposes a 750 is great on that engine. In the car a smaller carb would be much better. I recall that artical, but dont recall what RPM it was buzzin to. but a fairley healthy 6500 RPM 355 will run great on a 670 vac. sec . or 700 mech if its set up right.

Normally this is tru, but sometimes you will have an application that requires more fuel. On our impala smallblock (355) we are running a 750 Race demon and it is just enough fuel.

As far as 3" exhaust goes, normally you dont need to go that big...but is it stupid? No, I have 3" exhaust on my truck with a 400 smallblock and 8.2:1 compression. It also has 1.5 rockers on the intake side of everyhting and 1.6's on the exhaust. This is simply because I would rather not have a nitrous explosion because I failed to get it out the exhuast.

stepside454 · 02-06-2004, 12:39 PM

its not so much a fuel issue as air. you could have a 300 CFM carb & have to much fuel, or could have a 1050 dominator & have to little fuel, thats just a tuning issue of course.

bulkin'up73chevy · 02-06-2004, 04:50 PM

KK guys just some info what could I do fairly easy if I am say limited to around 5k$ Thanks should be enough. As far as miles on the truck go I believe the engine only has about 60-80k Is that to many?? What if I bore it and get 9.5 or 10:1 compression pistons?? Reguarding my truck it will be a slow process working on it cause it is also my daily driver. Thanks for all the info guys and keep posting more ideas.

LOHRTBT · 02-06-2004, 05:31 PM

i NEED TO GET THAT ISSUE OF CAR CRAFT HEHE

*1FaastC10* · 02-06-2004, 05:54 PM

you've got issues if you believe everything you read in magazines Tim. a 314hp engine wont make the cover, but a 400hp engine will. what they fail to mention is that at power levels like that, 9 times out of 10, the engine is barely streetable. while 400 hp is a "good" figure, we're dealing with a 3500#+ truck here, not someones stripped down race car. it takes torque to get a truck moving, not horsepower. for a street driven vehile, 750cfm is way overkill.

$5K you can do some really good stuff with that

Now if you want to keep driving your truck being a daily driver it would be best to have a long weekend to add your cam, heads, intake etc. But if you want to really get serious you can get either a crate short block (ZZ4 short block is a great one) to build up from then take your time and swap it out in a weekend for the one you have. Another idea is to find a reputable machine shop in your area and get a block that's already bored, cleaned etc. ready to go and add your parts you choose. You can get it assembled there or do it yourself if you are comfortable enough with this. All depends on how much time you want your truck down and if you want to spend the money on your engine in the truck now or build one up. IMO I would get another engine and build it up. This way you can buy items as you're $$$ allows. Plus then you have another great engine you just pulled out to build up for another engine.

I wasn't disagreeing with your advice, just the way you so eloquently applied it.

The locals here all know you are "the" smart @ss, and most of us love ya anyway. The new guy hasn't been informed....until now :p

Ditto on that.

I had a Holley 750 on my 355...worked perfect and never gave me any issues. It all depends on the engine, its purpose, and the vehicle it is in.

*1972C10* · 02-07-2004, 02:51 PM

I run a mechanical 750 DP on a 355 With 10-1 and some other goodies. It runs it fine runs alot better upper RPm than a 600

Never flooded with stock jetting 70cc up front 72cc in the back I decided to jet it down to 68 in the front leave the back 72 Just for the main reason that the primarys are Open at cruiseing Speed.

For an average motor 750 is way to much but if its built up with good compression high flowing heads and a good tall intake it may be just right.

But on the same hand a 600 may give plenty of perfomance alot better fuel economy and be less hassle than every worrying about flooding/ rich conditions

Few years back my cousin bought a 4wd blazer with a 427 mild cam alum dual plane and it had a pos dp q jet replacement holley that was in need of a rebuild ..

Well we figured get an edelbrock so we went and bought a 750 thinking Mild Big Block it can handle it . It flooded pretty bad but i have no knowledge of what was in it.
