302 or 347

In my personal opinion, go with a 331 or even a 342 but not a 347. The reason being you want to stay with a 4 inch bore if you can. Also, the advantage of the 331 is that the oil ring does not intersect the wrist pin, a common cause of short engine life and compression loss in the bigger 347 strokers. Some companies claimed to have solved this, but I dont put much stock in it. The 331 has a shorter stroke for better rod angle, and a larger piston skirt. A 331 WILL last longer and make about the same power, no question about it.

MYTH......
