I had a 351 Windsor stroked to 418 in my Cobra and it put out around 530 horse and 520 pound torque. Much easier to drive than my big block and I had more than enough power when on a track. A friend of mine has a 302 that is mildly upgraded and it is a really nice car to drive and has good performance, but nothing like the 351 strokers have. If you are going to be racing or running fast around curves, I would go with the 351 stroker. A friend of mine had a 429 in his and he couldn't begin to keep up with me on the track or curvy roads. But I am sure that in a drag race he would have beat me. I have always road raced and just prefer the smaller blocks.
Marvin,
What would be the weight difference between an Fe engine w/ alum heads, intake an a 351 with the same?
It would still be about the same as with iron heads. You would gain a small amount because of the size of the big block FE heads. I had everything but an aluminum block on my stroker but I don't remember what it weighed.
