I NEED HELP, this is my first attempt at fixing up an old car, it is 1970 mustang fastback, and I dropped of the 302 to get completely rebuilt! The engine has not been touched in 20 years so nothing will be saved but the block... My question, what is the better stroker kit for my needs 331 or 347? I would like to drive the car 4-5 days a week during the summer with enough HP to dust any blue haired kid in rice burner. There does not appear to be a consistent answer out there, I have tried to read as many articles and forums I can find to no avail. Any advice on a good set of heads and intake would also be very much appreciated! Thank you!!!
