"My son and I got a good 340 block and put in a 273 cast crank with SCAT rods and KB pistons. The piston/pin/rod weight was almost 200 grams under the stock 340 combo to keep stress off the lighter crank; re-balance was easy."
Thank for al the info, hadn't thought about a 273 crank. I'm considering everything and 400 is in the ballpark for HP I'm looking for. I've already learned a lot from all the great guy on this site and I'm sure I'll learn more.
