other than the pistons, rod, crank, and rings, is anything else different on a 347 stroker than what u can put on a stock 302? should i not go with a 347? i will drive it a couple times a week on the strip once in a while. i dont want my engine to blow after 20,000 miles from pretty normal driving with a little beating on it. what should i do? i can buy a 302 h.o. block an a 347 stroker kit for about the same price as a 351w.....what should i go with?
