598 Engine Advise
#13
I have the perfect intake for that motor SV632 Edelbrock powder coated black nice no corrosion $350 pretty much half price. As far as a camshaft goes if you want the motor to be happy and 850hp right around 6,000 rpm at 10.0:1 compression you need a 273-275 intake high 280's exhaust @.050 113lsa works great the more lift the better. That cam with those heads and intake will pull like a freight train to almost 6,000 rpm and be all done by 6,200-6,300 rpm.

I tried several different cams in my 598, all solid rollers. It depends on what you're wanting to do with the boat, enjoy the day with the wife and kids or go to the shootouts and see if it stays together. You may be looking at more than just a cam change, valve springs, push rods, rockers, more detail may help.

Thanks for all of the advise. I have no issue with running it above 5400. The engine was just torn down on Friday. The engine builder said it had a Callies crank, good rods etc. It needs bored out a little and he will get custom pistons for it. I'm waiting until next week to get specifics of the cam and top end as well as the rest of the components will be cleaned up and checked for problems. The engine shop is well known for their marine engines and I will get their recommendations as to how to build it hopefully soon.
