new to spitfire - engine build
Posted by Glenn Dowling on 4/6/2018, 12:58 pm
British car noob..apologies in advance. I am looking to build up my son's 1979 Spitfire motor and while I'm good with old Chevy's etc..BL is new to me. His model is a California 1500 with 7 or so :1 compression and associated emissions. I understand the UK/EU model was about 9:1, better performance (will be losing the emissions). My thinking is to bore to 30 over, buy the "high compression" pistons 30 over from Rimmer. The crank is likely good for a simple turn. Is the stock cam (new) appropriate? is there a different cam for increased compression motors? It has a weber intake/carb..stay with this or find the dual strombergs? Currently has a rather complex and cumbersome electronic ignition with vacuum "retard" (never heard of such a thing). Planning general head work surface, guides, etc..is the stock head/valve specs OK for this set up? Any help/pointers/pitfalls/stupid buttons would be greatly appreciated!
