the way my brain works , i dont want to go too nuts with the cam / top end , cause i still have a cast crank , cast pistons , thin rods , and about 500 hours on em
as with all boaters i want to find the most horsepower and the least chance for missing a weekend on the water come spring

Best way to check is to mock up the engine, stick a pushrod in the hole and set the rocker on top and check for clearance and position.
Shouldn't have to change anything though.
I have an engine in my magnum right now that is a 2 bolt main and I spun it up to around 7K yesterday under load and it didn't break.
You can make decent power with that stuff. Just don't try and run it for 500 hours between rebuilds.
You can get a pretty good crank out of the Summit catalog for 2-300.

E24,
Is the engine still in your boat or did you pull it? The only reason I didn't change my cam 2 years ago is because I left the engine in the boat and it was impossible to get the cam out.
If I had my engine out of the boat, I'd re-cam with something slightly bigger that set peak power right at 4,900-5,000rpm.
Are you/have you ported your heads?

engine is gonna come out of the boat , its gotta be easier to do heads when you can tilt the engine so the head isnt sliding off while your trying to put head bolts in
plus i'm gonna put a new oil pump in and so on and so forth
heads are gonna stay stock for now.

I have a great cam for you if you decide to get one. PM me and I'll get you hooked up.
Are you going to put in new pistons also. Those 330 pistons are really low compresion. You could get away with 9.-9.5:1 and really wake that thing up.
