Also to install this engine on the supervee you have to use longer header mounting bolts as the super tigre crankcase is wider than the aquacraft crankcase. the throttle linkage rod end will have to be trimmed off because it will hit the header manifold. The collet has to be cut shorter at the flywheel end because this engine is longer and won't quite clear the stuffing tube. And last you will have to reroute the water lines since the fittings on the water jacket are in a different position.
