That should make it go FAST!

Its also heavy, about 1100 lbs(I think) with prop. How does that compare to the weight of the engines the hull was designed for? Any balance issues?

Is that a bored out 350 or a bigger block?

I think it's a small block with a stroker crank in it, maybe from a 400 ci small block? Only downside I can think of is the combination of short Chevy rods + longer stroke = more side load on pistons. The 400" engines weren't very durable because of that, but maybe the 383 has longer rods or shorter stroke than the 400. It's a pretty popular swap among hot rodders, so it's durability must be better than the 400.

It is a small block. Nice choice Terry. When I was rebuilding my 25 the mechanic said that engine would be a good choice should I be unhappy with the amount of HP the current engine has. But I'm happy for now

Thanks guys !

This is probably to much info. but for us gear heads here you go.

The original 350 uses a B&S of 4.00 x 3.48

The new small block is 377 with a B&S of 4.0 x 3.75.

The stroker is a small block with a B&S of 4.030 x 3.75.

Weight is actually 12 pounds lighter than a 350. More aluminum.

The total package is approx. 300 # more than a straight 6. However I don't think that will change the balance to much since the boat was offered with 2 straight sixes and that would more than offset the small block. Any way with a extra tank up front and trim tabs I should be fine.
