Some of the things that won't transfer over are intake manifold and distributor. You will need a different one or spacers for the tall block.
I built my first one of these by mistake. lol It was a dummy block someone left in shop for a couple years. Did machine work before I found out it had a tall deck. Was the best mistake I ever made. The short comings are stock rods, even HD ones. I had good pistons for short deck so I chose to go with a 1/4 inch stroke and the long rod. 496. Mainly because these parts was off shelf items if I had to fix it fast. The heads are the limiting factor to high RPM, but they make great low RPM and for a budget racer, this is the ticket. Low RPM don't break as many parts. You will want at least a H/D oil pump also. There are a few of these that have a little more thickness in the cylinder wall. They where in 66 and 67 trucks or buses. They where a favorite of early fuel burners, before after market blocks. One of these school bus blocks was built, ran and qualified at the Indy 500 back in the day.
