I thought the 454 tall deck blocks were Bowtie and Gen V but with the Gen IV blocks were either 427 or 366 truck engines. Maybe if he posted the casting numbers we could sort this out.

The tall deck engines are awesome for reliability. They allowed the big trucks to use a taller piston so that they could add rings, and change the rod angle so they were better suited to running down the highway at high rpms for thousands of miles. Some of thise engines would go 250000 plus miles in a dump truck truning 3500-4000 shifting gears all day long.

Perfect for the marine world, just hard to find. If I were going to spend that much cash, I would just switch over to a tall deck aftermarket block. Then yo ucould have a tall deck 502 or whatever bore yo uwanted engine and really have a beast. Crank and rods would be the same. You are all ready buying pistons and a block, and the rest of the stuff goes on top. There might even be a taller piston out there somewhere.

Seriously good way to build an engine. Crank in the tall deck 454's etc were still 4".

If this is the case, there is nothing I'd reuse from the blown shortblock. I'd build or buy a 502.
If you have the extra cash to build a tall deck then a 540.
The boat is for sale though so...

sell your blown motors parts and buy a new or newer take out i,ve had a lot of boats rebuilding a marine motor is hard because the load on the motor and the high rpm if it,s not perfect the motors keep shaking apart you might get a couple of runs but you,ll allways be working on it

If that is the crank that is in that engine it night be a good one, but hly hell that is a long stroke to be putting in that block.

I would never go bigger than 4 3/8 and that is pushing it

Go back down to a 4.25 crank and a flat top piston. You'll have much better results over all.

No wonder it came apart.

I just like them .
No it's not. They are old technology. Good blocks, but not as good as a modern DART
