    2.3l has 150psi across all cylinders, but small amount of water in oil.

    most likely the exhaust manifold is shot (really common on the pinto motor based OMG offering) hold on to your shorts when you find out what that NLA bit of hardware will cost you.

    Help a new guy out . Pcv valve

    you went thru the effort of buying a new wrong block and heads. why not buy the correct block and heads? 30hp is a concern a running used 1996 or later vortec headed 4.3 is under $200 from the local pull-your-part salvage yard.

    Cheetah 180V (1984) or similar outboard conversion

    dont know. thats up to you to look. doubt you will find a 19 foot tiller boat, most will come with remote steering and controls. you would be better off looking at a blue fin or other brand of boat vs an early 80's boat with rotten stringers/transom/etc.

    yep, same one I posted prior. BTW, if you order from From flow GM, it will take a while. your better off on oemcats.com, finding which GM distributors have the parts in stock and call them directly. gmpartsdirect (Flow GM) is slow as hell in filling orders

    Adding 100+hp. Would you re-prop ?

    remember, your drive is limited to 5500 RPM or less. Circle track motors spin to 11k. the XM270 is a small cam compared to what is normally in a circle track motor. it has almost no overlap and runs out of breath at 5300 RPM
