What is the power adder and what kinda racing or goals do you have for it?

IMO the 8.5:1 on the last setup is little low.

Hectorls1

I have a A&A V2 3.6 with headers . Something close to 700rwhp, the last one the heads are sold so its just the short block.

PEETYZ

I personally like #1 with some 243 heads not sure on those piston specs but I think you definitely want over 9:1 static compression. A simple forged 347 will do some work look at Ricky (69ls6)

IMO for a simple set up forged 347
(Static compression around 9.5:1 or so)
Stock crank
Stock 243 heads
Forged rods
Forged pistons
Arp main
Arp head studs
Ls9 head gasket
Blower cam (jam cam)

This should be good for about 900 rwhp with the right power adder such as Ysi etc

Or if you prefer iron I'd do almost same set up with a 370-390 iron but might do ls3 top end. There's lots of good combos out there. What's your goals?

BLOWNBLUEZ06

^^^^ this will work.
You'll need to max that blower out or get close to doing so to get your #.

ratt_finkel

What type of durability could you expect from this set up? Will it last for a few passes down the strip? Or can it take WOT pulls for 30 minutes in a row in 100 degree heat?

c7rvette

I would first focus on cubes, then on strength. my little forged 402 built by billy briggs with a Paxton can make over 900 rwhp with a flip drive. just my 2 cents. its strong as heck and could last you a long long time....all you need is a little meth. As for compression, I am at 10.1, at that compression, get your self somebody that knows how to tune.

PEETYZ

So much of this is in the tune and how you really drive the car and the limits you push it to. No forged set up is unbreakable but this is a pretty solid one for under 900 rwhp.

Ricky (69ls6) was basically on this set up for 3 years over 900 rwhp and I'm willing to bet hes put his car through many more paces than most all of us


His 347 also ran a 9.1@158 rowing a 6 speed with Irs suspension etc

larger cubes are nice but most of these blower set ups seem to work just as good if not better with a stock stroke vs a stroker crank

Just my .02

It helps when you drive your car like you stole it.

Maybe true but not every time you start the dam thing up.

I will be selling the engine in my '97 C5. It is a '09 LS3 399ci long block built and forged with all the good stuff back in June '14 by AES Racing in Elk Grove, IL.

It was installed and tuned by Speed Inc. in Schaumburg, IL. It made 701 whp with an A&A T-Trim. This is a very safe tune. The block is good to 1200hp.

I have probably 2000 miles on it. The car absolutley flies and is a blast to drive but my family has outgrown our home and the car must go to help with the down payment.

I will be writing up a big for sale ad with pics and prices soon but if you're interested, I would be happy to chat about the details.

Ricky also puts 25 psi+ thru that motor to make 1000hp and he has been into that engine more then once...

Many ways to skin a cat.... Just remember, smaller the cubes, the more boost its gonna take to make the same power as a bigger cube motor... Which one is gonna keep head gaskets better? Which one is gonna last longer? Which one has to spin higher to make the same power?(sometimes this is a good thing though, especially for drag/lsr racing, rpms is your friend)..


I'm all for big cubes/less boost... A 427 with 20 psi will make 1000hp much easier then a 346 on 28 psi....And have more power under the curve by a good stretch... Although it will peak earlier and nose over sooner...

No doubt you can make killer power on small cubes and lots of boost... For how long, that is the question.

But for 700rwhp...I'd stay 346...keep it simple.

I'm actually thinking of going small with the next build and just stuff some good rods and pistons into a 4.8 iron block, good head studs

I have a lunati 4.0 forged crank, and many have told me the factory crank is very iffy at 1k hp

my goal is 900 or so at the tire to run deep in the 9s and hopefully get to 150 (but just once, don't want a parachute!)

so my question is, use the forged crank with the small bore engine?

or broaden the rpm range

it seems hard to find a good deal on a short stroke forged crank which is what I really want, but not interested in paying 1500 either!!

I'd also like feedback on pistons

I like both the wiseco and diamond they seem to have good strength

leaning towards the diamond

where's the best place to buy these parts, I mostly deal with summit but with a more specialized turbo piston, I want to make sure I get the right part numbers and sizes

2003VETT

Stock motor has been going fine for me at well over 700

breecher_7

K1 Technologies/Wiseco offers a forged 3.622 stroke crank for around $800 and budget 6.125" rods with ARP 2000 bolts to match. Now if you were talking shorter stroke than stock, im not sure where to look.

As far as pistons go, both wiseco and diamond are good.. Diamond is made out of a better alloy though.

As far as a source for parts. I would start by contacting some of the forum vendors as they can usually work you a good deal. Give Brian Tooley Racing a call as well, they have some great prices on parts.

At what HP did the stock MAF become restrictive

Robert 2000

Yep I have a 6.0 iron block with k1 rods, crank and wiseco pistons stock stroke!!! Now to just get it all into the car.

Arun@Dasilvamotorsports

500 horsepower. But there are ways around that.

I would pick block #1

Would that be in the tuning or LS7 MAF?
