Default Which combo of CR and turbo for the NASTIEST possible forged 346 on 93 octane?

Limits are stock cubes and straight 93, NO METH....looking for the "fastest" possible setup.

I would get some dished pistons and bring the compression to about 9:1. That should allow you to play around with 15-20 psi without sacrificing too much bottom end with an even lower CR.

How much power are we talking here? 1000RWP, 1300RWHP? More? You'll probably want an iron 370. Fireball took an LS3 to about 1700 before it let go and filling the water jackets some would have saved it, but an iron 370 is a pretty easy swap and it is strong.

If you're set on a stock cubed motor, you can still make 1k.

He could probably go with another .5 point on compression and still be safe on 93. I was 9.62:1, 93 octane and 20* of timing and making 808RW with 19psi. 9:1 is probably good for 25psi, go 8.X:1 after that.

He said nastiest and fastest possible, 7-800RWHP is getting to be common. My car would hook from a 40 roll on hot tires, other than that, worthless. It was also stalled though, so it was either all or nothing basically, he may be able to pedal it in a 6 speed.

Very common.

I am looking to do a 347ci combo with about 10:1 compression. A dedicated Race gas combo. Small cubes, Small turbo, Compression and boost to make the power.

Of course this is all after I drop a Stock Long Block in the car and see what can be done. Yes I mean stock Long Block. Stock cam, Stock 241 heads, Stock. Just an Intake Elbow and TB.

Stock springs? Thats easy, it will float the valves.

This is far from my fist rodeo. I know how to make the engine live. My point is stock cam, stock heads, stock short block. Of course it will get suitable valve springs.

It however wont get 6.0L heads and a big *** cam.... Game on...

I guess "stock" and "just an intake elbow and tb" means something alittle different in BG.

I know this isnt your first rodeo...but it better go faster than your last attempt(with the built motor and fast xfi). Just when I was wondering what I should do with the fireturd.....

First off Josh's car when he had it was only making 8psi and was running 17" drag radials on the back with a completely stock suspension. The car ran 10.7's@132 and made 563rwhp. Josh made a big step with the car and put a complete suspension on the car and put on some 15" pro stars. The car was never turned up when he had the car. After he sold it the car eventually went some 9.40's with the TC76 kit still on 60 pound injectors and ls6 intake with a small cam. A built motor is a moot point with the only being safety, it's not like it will make any more power than a stock motor will make. This isn't a pissing match. No reason to start one.

Yeah. I didn't know stock LS1 short blocks sported big donkey dick turbo cams in the 502 .

Brian pretty much summed it up on the old shop car.

Let's keep it fun. We are semi local. This could make for some fun weekend racing.

I'm not trying to turn it into one just stating the facts. Another fact is that car never went 9.40's, the fastest it ever went while billy owned it in the 1/4 was a 9.60. Im sure it had potential, but it didnt run the number in the 1/4.

It sure seems like you're making it a pissing match. I know for a fact the car went 6.03 in the 1/8. I was told it went 9.4 in the 1/4, but if you know it's a fact then you have no reason to lie. Fact is you can always find differences in cars. Is your car a true street car? Well that depends upon who is going to define what a street car is. To me the car was impressive for having a full interior, working heater, and stock suspension.

I was standing right there when billy told you it went a 9.60, I guess you just didnt want to hear it.

I will do the stock motor thing again next year to have some fun with you guys.

No more thread hijacking for me.
