hello all
i am putting in a long distance call for some advice.I recently bought what in my country is called a "cona" it is a 72 model with a 455 olds and a berkeley 12jc jet and is 18 foot long in the U.S i think you call them "tahiti`s". The problem is that it is very difficult and expensive to get parts for the olds motor and as i am a ford man i want to drop in a 460.I would like to hear from you guys what this mod would entail,(bellhousing,etc).Currently the boat does 100km/h (62mph)at 4000rpm the thing is,i do not know what sort of hp i need to get to the 130km/h (80mph mark).i also need info on the sort of hp absorbed by the pump in order to build the new motor so that it can reach the desired rpm,with out using gas or turbo.I don`t know if this is reachable,there is very little experise
out here on this sort of setup.
thanking you in advance
regards
