IMO strokers are so overdone--been there done that. I love an efficient engine and that means high HP/CI . There is nothing like a 7000+ rpm engine on the street and that just isn't going to be a stroker. Plus as a builder it will be more of a challenge to pull off a 550HP 340. I'm building a high RPM 371 (3.58") right now that I will get rid of as a good 340 block has come my way. Going to stroke crank to 3.425" (356 cubes) and let it sing. J.Rob
