EricJB Posted February 10, 2012 Report Share Posted February 10, 2012 Camshaft also effects how much squeeze you can get away with. I wouldn't want to run 11 to1 with a stock cam. But higher duration and a lot of overlap, not a problem. Still makes more heat, and possible head gasket issues if not addressed at assembly. Quote Link to comment
datzenmike Posted February 10, 2012 Report Share Posted February 10, 2012 I would say that two motors exactly the same but for compression... the higher compression one would run cooler because it is more efficient at capturing the energy and using it. Less heat is wasted into the cooling system. Quote Link to comment
EricJB Posted February 10, 2012 Report Share Posted February 10, 2012 You may be right on that Mike. My brain runs on Aircooled VW facts and figures, that I'm constantly trying to convert to Datsun. Quote Link to comment
ggzilla Posted February 11, 2012 Report Share Posted February 11, 2012 Hmm, higher compression results in hotter exhaust ... Quote Link to comment
