I don’t know what your budget is, but I would absolutely build a 540 if you can. It will do everything easier and allow you to build in the safe zone everywhere. I did it with a Dart block and heads HP 500 cam Eagle bottom end, Mahle flat tops 9:1, 1050 on a dart single plane. Even leaving power on the table at every turn, it makes 625 @ 5400. 150* water temps and 230* oil at wide open for a week. You won’t be sorry.

how is this for the cam?, it fits your split and lsa criteria, melling 22472 duration @.050 237/245 lift .626/.639 lsa-112, I can get it new for under $200 and yes its a roller cam.

For that price is it a cast cam ? OE GM amd Merc use steel cams even for black motors, not just blue.

Enough to get to Hawaii and back apparently. Seriously whats the approximate burn rate at full throttle?

OK maybe it was just a three day weekend. My liver thinks it was 7 days. Like the skipper it runs on rum.

Hard liquor weighs less than beer and I do make my best decisions when I drink the hard stuff so I have that going for me. How much could go wrong doing a 48hour bender at 50mph in me middle of the ocean.
