Ok I bought a bigger boat than I am used to, a 1978 Eliminator Sport Cruiser 20.5 ft. I love the boat so far. It drives better than any of my previous jets ( 21 commander & 18 Kachina), also seems to get on plane quick for its size and lack of power. It is stock as far as i can tell and the Old 460 is warn out which shows with its top speed of 52mph at 4200 rpms. The plan is to install a motor that I previously ran in my 18 foot kachina( .080 460 Ford 11.1 comp, Comp 300AR solid roller cam) in the Eliminator. That motor turned an Aggressor B cut impeller to 5900 [email protected] 93 mph, It was topped with a Weiand Tunnel ram W/2 750 DP holleys. I am no longer going to run the tunnel ram, I want to keep everything under the cover so i think it will be topped with either a Trick flow intake or the FMS with a 1050 Dominator. I bought Lightening headers also to keep under the cover, but I am not sure where to start with the impeller. Not sure how heavy these boats are. I was thinking that the Same B cut aggressor might be ok? Want to keep the rpm up, but dont wat to loose to much holeshot. I am also adding a rideplate and shoe, not suer which droop works good on these because it seems to ride pretty dry with just the factory Jet o vator. Any guys with this hull please send any advise my way, Thanks.
