The Motown block is an awesome piece, but Sherman warns against thinking all other common small-block goodies will be accepted without worry. "This additional bulge on the drivers' side bank provides a generous water jacket, which is great, but when I went to bolt the Jesel beltdrive in place, there was the bulge! I've had to machine down the Jesel part to fit, which isn't a big deal and won't affect durability in any way. But, it was time consuming and people should be aware of it. It's something I've seen in other aftermarket small-block Chevrolet's too--so it's not just the Motown."
