Re: 460 Build
Ok , its for a 17' inboard berkly jet drive. I first wanted to build a all out motor for it,but since have changed my mind. I have flat top with single valve relief LW 2602 pistons.cast iron cobra jet intake,DOVE heads extensively ported and gasket matched to cobra jet ports. I was looking for a victor,or stealth on e- bay for a good deal.
I have not bought the valve train for the heads yet or cam kit ,so i will use these head later for another motor,
I have since bought some D3 heads that have been redone,new valves,springs,valve job,some porting.So i am now building it with these for fuel reasons and the fact that i don't need that much motor in the boat as i originally planed to build.
So my D3 heads i have finished porting extensively on the exhaust side but ,
1.do i need to leave the intake side standard port matched or go out to cobra jet port match
2. For this level of motor would it be better to go with a standard port intake or a cobra jet port intake.I have the cast cobra intake but really want to get an aluminum one.so a
Stealth with standard or cobra port,or Victor which im not sure what port they come with.
3.I had planed on the 278 comp marine but i think that i need to go with the 270 now.
4.Do you think that the stock valve train would be ok or go to the conversion kit for the slot pedistal rockers .
5.Should i go ahead and use the windage tray that have already bought or save for another build.
i was thinking that with this motor , i will be shooting for around 400 horse or 450 ,and pump gas friendly,be able to run reg unleaded with careful timeing or super with more timeing , I wanted this motor to haul ass but it will be used to pull knee boarders and such more than running top end across the lake.
