Hey all, I've been slowly building up my 200 over the past few years, and looking for what my next step should be and toying with the idea of FI...
Right now it's a stock rebuilt block, bored .030, with a COMP cams 260H. Head is a large log with a direct mount Autolite 2100 1.08, and long tube headers. A decent amount of work was done to the head - 1.75/1.5 valves, 3-angle valve job, some polishing, dual springs with dampers. I'm also using a DSII with an MSD controller.
Head chambers are 54.5CC and I'm using a Victor gasket, so if I did the calculations right that would be 8.66:1 CR, just under stock. I've read posts that say you generally don't want to go above 8.5:1 otherwise you'll get detonation... Should I just keep it the way it is now and forget about a turbo? Anyone running a similar configuration safely under low boost? Maybe 6-7psi?
