I look at it this way, my current RPM is 4600. With better heads, intake and cam I will be able to spin more RPM, plus with more power who knows what i'll get out of it?? I'd be happy with 55 on GPS

And then some searches and you'll see him asking for aluminum prop advice, and then Holley carb tuning advice,,,,,,,,,,but yet, he says he's the exspurt.

I run a 350ho 330hp vortec motor with a holley 650 carb performer, rpm intake, msd ignition, roller rockers, and revolution marine wet exchaust and I picked up about 7 to 10 mph on a 21 ft hull 24 degrees with a ss prop 23 pitch. good luck

If you have a earlier shortblock in good running order, I don't see any reason the Vortec shortblock will be of benefit. IMHO.
Other than that the Vortec will have the hr roller lifter stuff.It will cost more than the $80 you spent on that short block to get that for your 88 motor
Those parts aren't a ton of $$$ new from GM though.
