Hey guys, some people tell me higher compression means higher horse power, but you need higher octane gas and fatter jetting, is this true, if so, to what end? my 1980 SRX440 has 140PSI stock and want to cut my head and squish area 40 thous, maybe more if it will give me more HP, and how does reliability get affected? anyone have any first hand experience with this??
