354 or 392? Hemi? Questions?
Guess I'll have to see exactly what he has.... I hope it's a 330 or 341. And a inch narrower would help alot. Is there anyway to easily get 350 hp 400 torque from one? I would hate to say ya it's got a hemi but it can't run... Or take someone for a ride just for them to be like should of put a 340...
350 hp/400 torque wouldn't be hard. The 1957 345 Desoto Adventurer made 345 hp/355 ft-lbs stock, although that was a 9.5:1 compression, dual quad setup. But stock none the less.
The "formula" is pretty much the same. Set it up with 10:1 compression, put in a decent cam, and go with at least a 4v manifold and you should be making 300+ hp, depending on the cam. And for the 330/341, I don't see why that set up wouldn't make closer to 400+ hp. The only problem with the Desoto's, actually all the non-Chrysler's and even the 331, is piston choice to get to 10:1. For the 330/341, stock pistons will get you to 9:1. But for the 276/291, you basically have to go custom forged, so you're looking at like $800. But Hot Heads should have all of the specs you need, they've been made before they just aren't a stock item.
But that's with a rebuild. Without one, only the 330/341/345's are likely to get over 300 hp. The problem with the 276/291's is, like the early 331's, they had 7 or 7.5:1 compression. With a bump in compression they'll make over 300 hp no problem, but I don't think a 7:1 276 would make over 250 hp even with a 4v, cam and headers.
