I'll be starting a new build with what I already have which is an 11:8:1 LME 402 shortblock with PRC 247 68cc heads and a Huron Speed V2 T6 kit+ all components. S480 turbo, injectors, fuel system, radiator, fans, ect.... Now I've received some input from several sponsors on here. Swap out headgaskets to lower compression, cam and let it eat. What other options can I take??? Would it be better to sell my PRC's and just get a set of 317's??? I know the best option is just to sell what I have and start all over, but I want to make this work. I'm trying to see what's out there as far as high compression setups.........

If you ever plan to drive it on the street, you'll need to run E85. Pump gas isn't going to be able to make any real power with that setup.

Agreed, high compression motors will hold together and loveeeee ethanol fuels, to a certain extent.

317's won't drop compression enough IMO. The cometic "custom" thick head gaskets would be the easiest by far, and allow you to keep the nice heads. I've run their 3mm head gaskets (.125") on one of my engines. Ran big boost (30lbs) and never had an issue.

my big motor bid great on the street @ 11 to 1 pump/meth.

E85 is just around the corner. I'm currently running a 4.030/.040 head gasket, 68cc heads, with 3cc pistons, .013 deck. So what would be more ideal, a 4.125,4.130,4.140 or 4.160/ .060 or .070 gasket???? And as far as pushrod thickness, 3/8"???
