[QUOTE="Nordi, post: 385490, member: 9253"] I have been doing a lot of research lately on strokers because I am about to build one. I am going to stay with the 302 block. That way I can say, "Look, it just has heads and intake":rollseyes The most I will push it is 331. The reason is even with the slightly shorter rods in the 347, it's still only good for 45,000-50,000 miles max and then will need rings. However a 331 is good for 90,000-100,000 without needing overhauled. Obviously the biggest determining factor is how you drive it, but tese are average numbers I have found. A 331 with AFR heads, Trick Flow Track Heat intake, X-303 cam, long tubes, and 1.7 roller rockers is good for around 475 HP fuel injected. The carburated one is good for 430 or so. Both running pump gas at 10.5:1. I have a buddy who runs a 331 in a 90 coupe that turn's high 11's. That's with full interior and full metal body. [/QUOTE]
