    Craigslist /marketplace or junkyard for donor motor?

    the only benefit of a "vortec" block is the vortec heads the downside is the electric fuel pump (yes, the mechanical pumps are superior to electric) all 4.3's from 1988 on were rollers (roller cam) so yes. you could put your non-vortec heads on a 1996 and later block. however upgrading the...

    very little benefit going to vortec heads and keeping a 2-barrel. sort of like trying to run a marathon while breathing thru a straw. (also very little cost difference in the intake) if you are planning on keeping the 2-barrel, save money, just rebuild what you have.

    Craigslist /marketplace or junkyard for donor motor?

    you dont want any automotive accessories (you cant use them) you only want a long block (short block and heads) as you need the marine accessories, rotating electrics and ignition system. you will need to buy a new intake as your non-vortec intake wont work on a vortec headed motor. if you...

    6" of water above the floor means the starter and alternator were submerged. the crank centerline was under water. pull the starter and alternator and go thru them. pull the drive and get the water out of the bellows

    Gas vapor out the secondaries at WOT

    or leaking exhaust manifold and rusted valve seats. BTW, since a new motor is 150 psi, if you have 180-200 psi, you either have water in the cylinders or you have a bad gauge

    you sure you have spark? the 1999-2003's suffered from crappy ignition trigger modules easy to check for fuel. with spark arrestor off, look down the throat of the carb for a stream of fuel when someone gives it throttle. if you have fuel, you may not have spark.
