Got any junk 426 blocks hanging around?
By the time that guy was done with them, they were nothing but scrap iron. That 547 ended up putting the crankshaft out the bottom in 3 pieces after the guy got greedy and put a 40% overdrive blower on the engine, which had 11:1 compression! The cylinder sleeves stayed put, though.
I've got a couple of 383 blocks, and a 426 wedge block bored out to 440- - - -maybe a couple of crankshafts and a set of wedge heads or three. It's been quite a while since I built any MOPAR stuff, and it's always more fun to spend the other guy's money! There's no substitute for cubic dollars, and I can have all the fun I want while somebody's paying me to tinker with his stuff!
