I can actually get some pretty significant increases in compression... the head gasket I'm having made will increase the engine compression over .7 pts (from 8.2 to 8.9:1). I could theoretically go as high as 9.1:1, but I fear excessive mechanical interference if I were to do so. |
Well if it doesn't have an ECU and it is carbureted then your car would benefit
from running premium anyhow, why go through all this trouble and expense
when a simple price increase at the pump would yield at least as much?
