Oh. I used to run and already have a 6 blade staggered warp drive. I think it’s 78 diameter. I currently don’t have any type of reduction drive. I just don’t know a ton about the specs on this 454. Apparently was built for a jet boat. Any comments greatly appreciated. I’d have better Picts, but it is safe under cover and snow.

I’m either thinking this 454 or a totally rebuilt 455 olds direct drive with mondello mods originally built for a jet boat. I could get either. Both fresh builds. Talk amongst yourselves!

This is the Olds snd what has been done. I also have a 68 x 68 x 40 wood, nickel tipped sensenich.

My last boat was a 16 x 8 Aluminum deep custom boat with a 460 Ford direct drive with 3 blade NGQ. Trying to find Picts of it in old phone. Picts to come.

Casey,

My suggestion, without a gear drive you are looking for maximum low end torque (below 3,000 RPM) where the stroker is going to produce the best. The 454 block will also give you the option of a gear drive in the future, which would make a huge difference on performance. As for the Oldsmobile, unless you are really into antique and cool, finding parts is gonna be an issue. I may be wrong on the big block, but I know the small block stuff had different bell housings between Chevy and Olds in the 60's and maybe 70's, so matching up a gear drive to the Olds might be a problem.

Also, that Warp drive is not a bad choice for a direct drive like this, but you should consider shortening the blades to make the diameter smaller. 78" is going to limit you to maybe 2,600 RPM. Those blades are probably old and chipped on the tips, shorten your setup to 72" and you can spin those blades to 2,800 and push to 3,000 RPM if in good shape, which gains significant Hp.

In the future, add a gear drive and go big on the prop, you should have plenty of room, but would need to move the engine stand.
I still think I-10 is the Mason Dixon line.

Awesome! Thanks so so much for the imput. I’m open to a suggestion to another motor option including a reduction drive, be it belt or gear. I just have access to these to motors now. That being said, I’m not in a super hurry.

Just trying to do it, and keep it simple, as you wisely suggested as well as be fiscally responsive. As if I have ever been that. Hence, the love of airboats. Hell, boats in general.

Again. I appreciate your time!
