Does anyone know what engine I can use that I can get 300HP or one that I can gear down to get the equivilent torque produce by a 300HP engine? I would prefer a liquid cooled automobile engine, but I may have to go with TCM. If you have the specs that would be great too.

The Chevrolet small block with a PSRU would be my choice;
The ZZ4 with alloy heads puts out 330 hp, the HO Vortec (Iron heads) 350HP.
If you can afford it, the all aluminum versions such as the LS1 would be great, and produce more than 300 hp.


You can't get an engine with more parts availability than these, nor one cheaper to overhaul.

I personally love the MP14 in all its forms and with all its idiosynchrasies, but it's now way over $20,000. If I had that cash lying in a corner, that's what would be hanging on the front of my biplane right now.

For 10k you can go to Classic Airboats and get a whole, almost ready to run Chevrolet engine package, complete with PSRU etc.

What, no radials? How about the MP-14?

Bruce :)
Sorry, I think I mis-stated the engine designation. I've seen it both ways, but I believe the correct (or at least more commonly used) designation is M14P.

The ZZ4 would probably be perfect. Anybody know what it weighs with or without accessories? and what its dimensions are? And even if it was cheap, I don't know that a radial would work because i need so methign I can stream line and I want water cooled.

The GM website had some info; this is for the iron-head 5.7 L Vortec (432 lbs inc. inlet manifold). I think alloy heads save about 40 lbs. Also gives dimensions here.

Its going on an amphibious canard called the mudduck.

So are those specs at the GM marine website going to be close to the same for all Chevy V8 engines?

Wow... that Mistral looks awesome. It is so time for something like that. I guess the only thing that would make it more perfect... would be alternative fuels that are surely coming. So, from that standpoint alone... my short term engine choice is going to be el cheapo... al reliable and el disposable. Then in a few years when we figure out what we are going to run engines on... then, Ill break out the EL Bucko's and by the logn term motor. Just my thinking at least. But the Mistral sure looks great and sounds great. Buzz
