HP predictions of 6L
Okay guys this is what I am to determine and could use your help also.
05 LQ4 block fresh bone (standard)
I need two pistons to keep at 9.4:1 comp but have a set of LQ9 pistons but need three.
Fresh polished 3.622 crankshaft with stock rods
02-04 Z06 .550 lift camshaft
Fresh set of 243 heads but will put on some yellow springs for the .550 lift cam
All this is going in my 87 Buick Turbo T, with a TH350, and 3.42 gears and it will be carbed with a 750 Holley, guessing I am going to need bout a 3500 converter and car will have a 175 shot of nitrous also. And going to be ran by a MSD system with a Victor Jr intake.
With the lq4 pistons and the 243's comp should bump to around 10:1 but with lq9pistons it would come up to 10.6:1 or a little more so with that saying can the lq9 pistons be use in this block without serious mods.
But can I get 450 before nitrous with the setup as a LQ4 with 243's and the Z06 camshaft.

What is the stock compression of the LQ9s with the stock 317 heads? I thought it was like 10.0 or 10.4 stock? So if your running LQ9 pistons and 243 heads you were close to 11.0 compression?

put it this way, i have a stone stock long block ls2 in my 67 camaro, 3280 lbs,3.73's, richmond 5 speed and first pass off the trailer,totally untuned and spinning to a shitty 1.68 60' it went faster than 3pedals car has.
dont believe the hype that you need more than a 243 head to go fast. the heads have NEVER been off my motor,

LQ9s were rated at 345 hp from the factory - so obviously 350 is going to be the extreme bottom end of your new hp range
Displacement alone is worth more torque - not a whole lot more HP though.

Get a custom cam for that intake! Carb style Intakes require different lsa compared to the stock style ls intakes. Your going to leave power on the table with the z06 cam.

Mad as hell!!!
I ran into a problem I bought three pistons and bought rings for an 04 which mines was and the pistons came from an 04 but must of be a late model cause there 05+ pistons and now the rings want fit. Guess I got to find some 04 pistons or get three ring pack sets for the 05.
I have been thinking of selling the cam and get a carb cam but on a very strict budget also with this build.
