Are Washingtonians allowed here?
I need some help. I'm a waterskier with a malibu flightcraft. I found a 77 bubble deck Tahiti that I may buy on saturday if all checks out. It has a 454 that broke an exhaust valve. Its repairable with a new seat, valve job, bore the block.. etc. I believe it is a 68' closed chamber corvette head on a 80's something block. I am looking to build an approx. 500hp+ engine for it... or more is good. Is this possible with what I have to work with here? I'm on a budget as this is a second mess around boat. I do have a little money to throw at it but want to keep it simple and smart, but not necessarily simple and SLOW!
Anyone have a good running closed chamber 454? Or do we need more here? Tell me please.
Are the closed chamber heads limited in top end rpm? Good or bad for boats? If I built it the way it is now but with the right cam pistons etc..what hp/torque would I be looking at approx?
Or if the crank turns out bad should I do a stroker? Like a 496 or somethin?, but I don't think the closed chamber heads would work for that?.. would I need some open chamber heads for that? Like 049, 781, or 990?
Oh...and I can't imagine this hull is any good over 80 mph is it? I guess I need to keep that in mind if I can actually come up with the engine/pump to do it.
...just some food for thought I guess. Thanks.
