I've got a '68 Cheetah 16' I just bought to fix up.It has a 4 bolt 350 in it now.It has a Berkeley 12JA pump with an aluminum "A" impeller and Place Diverter.My options are pretty open right now on engine build.
The engine had a set of 882 casting,open chamber heads. I've got a pair of Double Hump heads and also a pair of new aluminum big valve,closed chamber heads.I was thinking along lines of the aluminum heads,a Comp Cams XM270H cam kit , Edelbrock Performer EPS intake,750 Holley and has a pair of long tube headers which look to be an old set of GIL or REWARDER's.As far as compression, 11.0,10.01,9.5?. I'd like to be able to run pump gas and be able to cruise as well as open it up.
My second thought was same setup as above,but with the Comp Cam XM278H and a Edelbrock Performer RPM Air Gap intake.I've also got a 1968 Chevy Z28 302 H.O. Factory High Rise Aluminum intake,GM #3917610. Didn't know if that was a good choice or if it was geared more to high RPM.
I'd like to have a fun,fast jet boat,noy just a wideopen only boat.Decent fuel efficiency never hurts either!!! Any and all input would be greatly appreciated.
