Hello. My name Tan.

They are the same base engine. The only difference might be rotation. You could have gears or chain for the timing components on cam and crank. The chain will be standard rotation LH and the gear will be opposite rotation RH. The rotation is determined at the rear of the engine flywheel end.

Both engines are GM 283 cubic inches.

Post back with questions and concerns.

Thank you..............Tan
