i have no idea man, i take what i read with a grain of salt specially from the forums, i have ran 12:7:1 cr without issues on 93 octane gas anything higher dunno would be and mostly only use race fuel .. NA setup 11:1 or even a tad higher is fine. but thats me. i sit right now on my lq9 setup somewhere around 11:5:1 or a tad lower, patrick told me but hell its been along time lol

 

how did you get that high with L92 heads they are 70cc stock? You must have milled the hell out of them.

 

Possibly, my bad..

 

my bad, i was still stuck on the 5.3 heads on my setup, i can see where some confusion may have came in... the setup now with the ls3 heads are 11:1 or just a tad over, the other numbers i mentioned were with the prc heads on the lq9 short block, i apoligize if i confused ya

 

Very nice results!!

 

not sure of before torque cause i never had it on the dyno. it was around 360 or so if i remember correctly. i didn't measure the chambers but they should be around 61cc according to texas speed. i used 7.45 pushrods.

if i did the math correctly compression should be around 10.6ish.

Thanks!!!

 

i was impressed this truck ran pretty good and felt strong....

 

congrats on ur 400+ pull.... i have a 5.3 706's milled .045 and i used a 7.350 pushrod...
