Hi guys

My plan for stock 5.3 lm7

Thunder Racing cam Trex V.2 - 242/248 .608/.612 110lsa +2
7.400 taxes speed pushrods
0.040 cometic head gasket
Ls7 lifters
Non toch heads
Do you think the piston will touch the valves or it will be fine ??


BTW -0.008 deck height 6cc piston volume
Heads chamber 61.15cc
Compression ratio 11.8:1
I will get 200 - 250 shot plate nitrous

 

With a cam that big, I would just go ahead and assume the valves will hit and check PTV to verify.

 

My question
Will the piston Touch the valve ??

 

Yes, they will.
