As to camming; There comes a point that one more cam bump takes the vehicle out of the realm of being streetable and also a point where more cubes is just a better solution.
140mph in a short wb, narrow track, first gen Barracuda, is really pushing the envelope.

The GV comments were just to excite and entice. It was a very hard economic decision for me. But, in hindsite a great sacrifice. All muscle cars shoulda come with a factory 5-speed.Doing the chunk-swaperoo gets old fast.

Thanks for the clutch info, been collecting experiences for a while now. My favorite was the OEM big block BB 10.95 PP and Disc from Chrysler, but it has a very high pedal pressure (broken linkage and overdeveloped left leg muscles). Always a smooth engagement, never slipped or broke, and lasted forever. However, I don't think I want that high a pedal pressure any more.

I was thinking of other makes, where going High Performance requires more than a cam and valve spring change. 140 MPH in 64 Barracuda was no problem, straight, true, smooth as silk. You just needed plenty of "line of sight" in front of you. The Speedo went to 160 MPH and 140 MPH was plenty fast, requiring full concentration. Since my 66 is a street only car with plenty of power, the OD will work fine. The GV OD does sound sweet, at this point in my life it is not worth the extra complication and expense. I'm glad it suits you.
