V-8;

I don't know,but I have a buddy running a 377 stroker putting out approx. 435hp.... Using a stock offset ground crank and an early 70's block.... Motor has about 20,000 miles on it and I'd guess at least half were put a quarter mile at a time on NHRA tracks.... He shifts at 6,000 rpms and has a 6200 rpm chip in his MSD box,it still together and actually never been apart....

The 351 block is pretty tough as are the crank and rods.... I would use the crank,but for anything over 400 hp I'd feel better with aftermarket rods....My guess is the block could safely support 500hp all day as I've seen a lot of 392 strokers putting out that number and some are raced pretty hard....
