I don't want to use a power adder quite yet, and I don't want to touch the head. I am talking bolt-ons that will make a noticibible difference. Here is a list of parts I have now: CAI gutted upper and rounded lower slider cam with the specs of the A237 (set at +4) long tube pacesetter header off road exhaust with dynomax muffler (2.25" except tailpipe which is 2") Right now, I seem to be around 110-115 flywheelhp. What is left for bolt-ons with a noticible gain? The ignition is excellent from the factory, I suppose I could get underdrives... but I didn't think those made much difference. What is left in it without power adders or head porting, or did I max it out?
