Nice Doc, I finally get to "see" the Vette (w/o the cover). A friend of mine has a very rare 68 w/327-365Hp. Very rare to have that engine in the "changed" body style. (the went to 350s)
Doc, you got everything right except the long stoke, just the opposite. In fact, they needed a long block (front to back) to accommodate the large bore. As Lee points out, 460 had the same bore, and still a relatively short stoke. The motor was actually designed by a former GM guy that Ford brought over.
Putting an aluminum intake on an FE Ford motor saved about 70 or 80 lbs of weight, the intakes on em were that big!
One of my biggest races when I put the 427 in the 70 Boss body was against a guy with a really built 440 in a 67 Satellite. The car had custom paint, and was gorgeous. White, with sparkles, and Blue ribbons that changed in shade. He had a lot more money in his car than I did, but I managed to out drive him and win.
My car was built on a shoestring budget. Got the 427 short block when I was up at college for $300, and the pristine 70 Boss body (the engine had spun a bearing for the 2nd time) for $800. Anther guy was trying to sell me a 56 T-Bird with a removable port hole roof for $900, but I did not go for it cause it was an auto! That is what it was like in the mid 70s. Wish I had a lot of money and a large barn or garage. I had neither!
