The specifications are 230/236 Duration, 298/610 Lift on a 114 Lobe Center.

The pistons are under a greater heat load and run hotter, hence, they are expanded more. Remember, aluminum expands a lot with heat. 2. Marine blocks run cold and therefore don't expand as much as automotive blocks.

Stock 502mpi with the intake dividers cut down and a bit of porting, stainless marine exhaust, run on the dyno with all accessories, wet exhaust through GGB mufflers.For anyone that needs to install pipe plugs with ‘allen head’ recesses, hex bolt heads fit right in the recess.
