piston/cylinder head question

jefflock, I had the Hays street/strip gold set-up,listed at 3400 lbs,used tge 10.95 pressure plate and 10.5 disc. It was a great feeling to side step the clutch at 4000 or so...with the 3310, I used the black secondary spring;secondaries never fully opened but it just kept pullin' and pullin'!

moper,guess I wanted what I had, cake and eat it too! probably the best for now would be the dished 360 pistons already in use along with a set of Magnum heads. cam accordingly and be able to use a full advance curve instead of cutting back on it to stop knock.

OR- pop-up pistons, oc heads,big cam,pump gas and water/alcohol injection!!!

maybe down the road. Thanks for the input! Bob
