I always wonder how guys can only run in the 15s with the 318. my little teen was a bone stock bottom end with steel shim head gaskets and .020 shaved off the heads cause they were warped. stock eddy performer and 600 eddy carb. even ran the 318 exhaust manifolds. gears, stall and traction should have any abody sub 15 sec et. i beat the piss outta mine and it was my daily driver.
