LOL he's definitely doing better than me, those 243's help a lot. My LQ motor only put down 289rwhp with a torquer v2 cam. what kind of spring/rocker setup did you go with?

I have unported 243's and a ms3 and i put down the same numbers as you did with nearly stock compression. It could be a difference in the dyno but i think there is more room somewhere.

The 408 ft. lbs tell the true story. If this was a 346 with the same combo yes at optimal tuning condtions and so on it would make 430 with that cam and heads but not 408 ft. lbs of tq. prolly 380-390 TOPS! He is low on compression with the LQ4 pistons. He probably isn't even at 10:1 more like 9:8 or lower. Bump the compression up once you stroke it with some forged flat tops and throw a fast ported 92/92 on it and you will be at 450 easy.
