I think I'm going to rebuild my motor. Too many problems recently with blown head gaskets, leaking intake gaskets , etc. Trouble is I'm not sure what I have now, other than it is a 92' roller motor and I have the Weiend blower of course. I would like suggestions on rod/piston combos to achive an 8.5-1 CR with the existing twisted wedge heads. Not sure what the stock cr would be , cause I'm not even sure what this short block is.... I am going to have the machine shop do the teardown to see if they find something ill. I'll have to check the cc on the heads but I'm guessing maybe 58 ccs?? I believe they are track heats. Hooked On Boost, or anyone else with this blower-- feel free to jump in here and let me know what you think I should be using, or whats working for you . Thanks guys.
