going in a chevy CAR (not truck).. not sure what yet...

mainly drag however I would like it streetable for weekend crusin
roughly 400hp or so 11's would be a good aim
twin turbo setup

btw on the clevitte main bergs do I want 3/4 grooved or full grooved

im getting a parts list setup I will run it by u guys before I order then I can get the OK from u masters out there

Dave

ok here is what I have an idea of so far

through summit

Crank
esp-103503480

rods
esp-5700bblw

main bergs
cle-ms909H

OR

cle-ms909hg

rod bergs
cle-cb663h

OR

cle-cb663hd

main studs
arp-134-5601


will all of this work and be correct for my setup and would tis be the right stuff to buy???

For 400 HP, why would you go thru all this expense? You can get a Gen III 6.0L engine (364 CI), install a LS6 cam and LS6 heads/intake and get 400 HP doing nothing more than swapping parts. These engines have 320-345 HP right from GM and they aren't that hard to find (and for a lot less than rebuilding a complete engine). Toss a Magnacharger on that combo and you'd have well over 500 HP.

Is there a reason you think you need a turbo or a supercharger? These systems are expensive, and for that amount of HP, they really are not needed.

The flow characteristics for the Vortec heads are for cars with EFI. Without knowing what car the engine is going in, how will you know what oil pan to use? What accessory drives will work? I think you need to rethink this just a little bit. I don't start any project without think the whole thing through.

sorry u feel that whay but this is a custom project that me and my wife are going to do..

I want a twin turbo setup.. if its 500hp then cool... I have a 350 block already and this is what I want to do..

the car is not as important since the oil pan will be one of the las tthings I get...

im more worried about getting the "engine" assembled..

it will prolly be a 70's split bumper camaro seing that is what my wife would like..


btw whats a waste to u may not be to me

Just hate to see someone toss money they don't have to but I understand the bling factor. That's my reason for supercharging mine. But, understand very little interchanges between the Gen I and Gen II engines. Most of what was made after 1990 is specific to EFI systems. The cooling systems can also be different. Most Gen II engines have reverse flow cooling systems.

This is what I was getting at. Mismatching parts can and will cause major problems. I would discuss you part choices with your machinist. They will be the one who will have to machine and balance the parts you supply them.

If this will be an engine that will see a heavy foot, make sure the lower end is all forged. Discuss head and cam selection as a package, as one compliments the other. If this is to be a street car, I'd keep electronic EFI as part of the package. I personally like superchargers as the torque is more usable where a car does most of it's business (1500-4500 RPM's).

Now, step back for a minute. If 400-450 HP is truely your target, and it definitely has to be a Gen I or Gen II engine, I'd look at a GM crate engine like a ZZ4 or Fast Burn 385. These engines have approximately 9.5:1 compression can still be boosted (less than 5-6 psi), and still run on pump gas. You can not build an engine for what you can buy these engines for and you get a 2 year/24,000 mile warranty. Toss a Vortech supercharger on it a get 500+ HP.

And because of the popularity of the newer Gen III engines, different companies sell 2nd Generation Camaro subframes specifically set up for these engines. Gen I and Gen II engines can not make the same power of the current engines (all things being equal), and they are just about as plentiful.

As for wasting time and money, this was more along the line of mismatching your parts, not using old Chevy stuff. But this is why you need a plan before you turn a wrench. Without a plan, projects turn into loose parts in the garage.

well this is out of a 02' chevy van. the block is bare I am gogin with a eagle steel crank, forged rods, forged pistons, clevitte bergs, arp hardware

as for cam and head sI will buy those in conjunction..

I want to do a twin turbo setup.. not supercharger anymore.. I was planning on doing a root supercharger but now I want to do a twin turbo since I have the parts and means and good deals on the turbos and intercoolers

Dave

FYI, all 350 Chevy crankshafts are internally balanced. Swifter has a good point--what is the purpose of this engine? Because it will make a difference in terms of advising you what to do.

I already stated the engine will be dropped into prolly a 70's split bumper camaro...

it will be used for driving on the street once and a while (maybe 1-2 days a week, no big driving) and then track driving too

Dave

Okay, I hope I am not insulting your intelligence here, but do you know what a twin turbo set up costs? Go to Gale Banks website and price one if you don't know because you are going to unload a sh*tpot full of money on this project. If you have deep pockets, fine--that's your business, but if you don't you should find out if it is within your means.

"ok when buying my crank... do I want internal or external balance??"

internal

"also since I am buying a new crank (and rods).. I only need standard size main bearing and rod bearings right"

yep

Call Joel Britt at Arizona Turbo and tell him what you want to do. He can fix you up with a pair of low-tech T04B Schwitzer turbos that will work for a reasonable amount of money. Talk to him before you purchase any parts. 602-253-9953.

I have my own parts business and I get direct pricing with lots of suppliers including turbo suppliers.. the turbos wont cost me anymorethen 300 or so each.. thats new/rebuild items..

the cost will be in the custom headers.. as for intercoolers I get them at a low cost too..

thx for the answers to the rest of my questions.. im not insulted at all... but I do have an idea and wont bend this is something me and my wife REALLY want to do all I am asking for is a nice group of guy like yourselfs to lend yoru mind to help me with figuring this stuff out and getting my project to life

thx agian guys I like this place alot!!


Dave

btw on the clevitte main bergs do I want 3/4 grooved or full grooved

The 3/4 Groove Hi-Performance Main Bearing provides the best of both worlds in a Main bearing. The 3/4 groove allows for the most efficient oiling to the rods, yet maintains full surface area in the most heavily loaded portion of the bearing. Crankshafts using the 3/4 grooved main bearings will not need to be cross drilled which will save time and money while improving crankshaft strength.
