Any interest in sleeved down 350 blocks?ive done Plenty of sleeved down blocks and seem to work pretty good,but have been mostly 454 down to 396.the last one I done ran the same as the dart that they had been running.they switched all existing parts over to the sleeved block so they could build a new engine with the Dart.this was std bbc cam tunnel and lifter bore set up.........Victor Penrod
