LS3 Boost Compression

I know this is a redundant question but I cant pull the trigger on these pistons n rods. I have a LSA blower that will be going on once I forge my stock motor. But the big question is 9:5.1 or 10:1.1 compression. I will be running meth with this setup. Would like to be over 700whp but as long as I can hook n book im fine. All suggestions and knowledge on this subject are much appreciated. Thanks

I'm 10.4 and boosted, no sense giving up the power. A good tuner can work with the compression...

Higher compression means narrower tuning window so make sure you have a good tuner (not that anyone would knowingly go with a bad tuner).

I'm going 10.5:1 with twin turbos.

Pat G. is a first class tuner. Have you asked his opinion on it since he will be tuning it?

My new engine will be 10:5:1 but I'm running e85. Ask your tuner
