I agree. Stay away from the Ebay remans unless they are from a reputable engine builder. I broke a GM forged crank in a 355 solid roller engine years back and replaced the shortblock with a Jasper Marine shortblock to get back on the water in mid July. It was a .060 over 2 bolt 010 block with stock rods, pistons, crank etc.. It was assembled correctly and I put 367 hrs on it spinning different combos from 5200-5800 Rpms. It currently is a spare in the garage.

Do yourself a favor..... Enjoy the boat for what it is. If you really want to gain speed or handling which you have indicated, save yourself the frustration and buy a boat that has your desired level of each. You will be money and stress ahead in the end. This is fact.
Good luck

Lots of good deals out there on used boats, and the value of our older boats is not keeping pace enough to justify spending a lot of money on engine mods - unless that is just your kind of thing. Just good to know that going into it. You will not likely get much if any of the money you invest back when it is time to sell.

all the more reason to get a diff engine to play with. throw the 305 beck in it when you realize it ain't gonna go faster enough. find something faster with a bad engine...

When I was messing with the 350s in my Chris Craft Stinger the best mod I did was to replace the stock lo-rise intakes with a high rise Z-28 iron intakes. I picked up 400 r.p.m.s and a lot of torque.
If you are fresh water cooled or only operate in fresh water you might get away with an aluminum version of the same. It would probaby cut 25 pounds (each). I did make additional gains with heads, cams,
and roller rockers but it was a huge expense times two motors for about 5 m.p.h. gain. I also had to buy new props. Before I'd go to that expense again I would shop for a faster boat as others have
suggested. Good luck!
