You know that’s a solid point, I’ll check thank you!

Without knowing whats in it for cam and valvetrain, keep it under 5200. pull the oil cap and look at the rockers, are they regular stock stamped steel or do you have crane gold rollers??

the motor is probably around 400 hp or a little more, Id prop it around 4800-4900 revs, what does the boat weigh ?

Crane gold rollers

24 Pantera trs older hull so little heavier idk 3500lbs ish sound right?

So somebody at some point put a little thought into the valve train, is it a mk1V, gen 5 or gen 6?? The timing cover will tell you...

Motor was built by Bullet Marine in Ontario. I got it from way upstate NY on St Lawrence River. Fresh water for 99% of its like. Eat off the motor tranny and drive

I know 4 bolt main forged crank cam heads gold roller rockers and performance springs. Spec on cam I don’t know. Aluminum exhaust manifolds imco risers

It sounds like someone planned on running hard, so you can do what the rest of us do - beat it hard until it breaks! If it doesn’t break then you’re golden and if it does then it’s time for bigger power anyways!

Previous owner said put the sticks down and go all day I had it built for it lol. I’m just trying to dial it in. A big block reving over 5k I cringe lol unless I know it’s built for it. I have a call into builder like to know specs
