I have a 427 Motown 350 journal size solid roller motor with Dart 227 cc heads.
I bought the Bill Mitchell block and rotating assembly kit with 20 cc dished pistons. I'm running 62 cc heads and .041 quench
I totally agree on getting the tall block it would save the hassles of clearancing the rods and cam lobes. If I had it to over again I would have bought the 4.125 stroker crank. You might as well make it a 441 or 447 ci. The cost is the same. The .030 overbore to get 434 ci was a $150 option.
I went from hot rodded 383 to 427 and traction is a real problem with these 600 hp class motors. Mine just pounds the 7000 rev limiter in the first two gears if you floor it going slow.
