Default will the G5X-4 cam clear pistons in stock LS1 short block?

will this cam clear the pistons or i will have piston to vlave clearance problem?

i'm not sure but i might use ported stock heads with stock valves or AFR 205 heads with 2.055"/1.60" valves.

so will this cam with above heads ( with the valve sizes indicated) clear the factory pistons?

both heads will not be milled.


so the compression might still be at 10:1.


i'm thinking of using these combination with QTP race headers and FAST 90/90 until the new L-92 block apears.

thanks for help.

I don't think the X4 will clear with that large of valves. I hope you proove me wrong though.

as long as your heads are unmilled and have stock valves you are fine. I do believe that the AFR's will fit due to their deck height. don't quote me on that, but I think you will be ok, give LG a call just to make sure, they set me straight with my x3.
