Per my previous post about 11.87 to 1 compression, if I buy the parts I had mentioned which are used and a great price, which inlcludes a set of ported/polished LE3 heads, the heads alone will bring the compression of my Lt1 to 10.8. Since a stock Lt1 is 10.5, would raising the compression just this much have much of a disadvantage of turbo charging for low boost below 10#, below 7#s with pump 93 gas, maybe get alky injection later for a few more lbs of boost later??
Any opinions?
