I've done it a dozen times or so. It's not that bad.

So I started taking apart the easy things. Drain the oil-black. Spark plugs- no metal. Exhaust manifolds off. Valve covers off- little bit of milky oil sitting in the grooves by the valves.

Found the issue. Oil pump was going out and my crank bearings fried and my rod bearings as well. Now I need to get my crank machined.

Issue was that I was cruising and I got a lot of blow by coming from my breathers and loss my rpms. I couldn't plane. I could go to 1200 to keep my oil pressure in a safe spot.

. Ouch. That sucks, sorry to see that. You out did me. I floated a hand full of valves and flattened the cam. Keep up the progress report!

Any input about that cam?

Need more info on the build/boat-

What Heads/intake?
Compression Ratio?
What impeller in the pump? What pump?
What Exhaust? Looks like logs ans snails in your pic.

The Gen. V 's I've seen had peanut port heads, and NON Adjustable valvetrain (read: airflow limited), and will have to be converted to adjustable rockers for that cam.
Don't forget springs to match the cam.
Is ti OEM roller?

That cam needs more intake lift/duration and/or less exhaust lift/duration, IMHO.

With logs and snails, I'd shoot for 235*-240*(max) @ .050" to keep reversion under control.

I'd go with 781's or 049's or other large oval heads, Eddy Vic Jr Intake, 750 holley, comp cams 280AH (232*/237*, .547"/.547"),
Or XM270H (226*/236*, .544"/.547") or similar, but I won't use another 'flat' tappet cam...I'd go ROLLER.

Just an Opinion

Thanks for the info! I wish heads were in my budget, along with rollers, but I am sticking with what heads I have. I don't think I have the heads with the peanuts I believe they are rectangular . I will look when I get home in about 2 hrs.

Get casting #'s of the heads.
need to know-
Intake manifold
Type/style of pistons for compression ratio
exhaust system
Impeller cut (at least "as built" cut)

Over camming peanut port, non adjustable Gen V heads is futile and has catastrophic results, Don't ask how ($3500 mistake) I know
