Im gonna have an s/c trim @6-8#'s with typhoon intake, 70mmtb 73maf, 30# injectors, 255 gph pump, full exuast, msd btm, power pipe with stock bottom and heads. Will the e-cam make a significant difference with this combo rather than retaining stock cam...reason is Im trying to keep this as close to smog legal as possible in california....I do plan on putting edelbrock or trick flow heads on later (after I blow the head gaskets)...should I throw the cam in there while I have the intake and timing gears out.....how difficult is the cam install...thanks in advance
