will go for H-beams for sure, its scary to think of the fact that these rods have survived over 450horsepower and over 7500rpm screaming so many times and even a few late night runs on 150hp nitrous and that they havent failed even with these stupidly heavy pistons but i wont take that risk again fore sure no mater if i build the 340 into a stockstroke high rpm machine again or stroke it out for more cubes(depends on money, but iam real close to be able order up everything for a stroker build) there will be some nice new rods in it!
thanks alot your knowledge helps alot :)
