I suspect the combination of that hot cam and the 4-1 headers has both moved the HP peak up fairly high and reduced your low rpm torque quite a bit. I had a similar setup on my car, but with a 1296 motor. It screamed at 5K+, but was gutless below 3K. A milder cam and stock header have made it much more drivable - though I miss that top-end rush sometimes! With the stock manifold it is out of breath at 5500 rpm. I think a 4-2-1 header can give better results than either - maybe a nice stainless one next year.....

Listers/NASSers,

Well, it's been a long time coming, but my Spit is finally back on the road. After several years of tinkering, and some of not much tinkering, I finally broke down and took it to a pro for some tuning. I played with it for a long time and just felt I wasn't getting anywhere or learning anything, so.... Engine has been rebuilt w/ 9:1 pistons, Kent hot street cam, dual valve springs, dual SU HS-4s (used, rebuilt), Kirk Racing header (4:1), electric fans on brand new radiator, etc.
