Cab, Do you recall what kind of numbers that combo pulled? And also what kind of head flow numbers you had for that cam to use? That sounds really close to the combo I am running in my 526" except I am using the TrickFlow 270's with some port work. I haven't had it to the strip yet but it behaves remarkably well around town for that kind of combo. 13" of vacuum at idle with a reasonable convertor in front of it. Response-wise it amazingly snappy through the entire RPM range.
