So they weren’t lying…

Just bought two 330 Desoto Hemi engines, one without main caps :-( also, I'm wondering if 318 or 340 caps will work with an alignbore. I did get a super rare Desoto tall deck cam made of unobtainium. The other was almost complete.

So, is there a 354 hemi?

Being able to use 318 or 340 caps would certainly be cheaper than buying new ones.

Unfortunately, there is no 354 Hemi, just the crankshaft from one. Now, the main journals and crank journals are the same size between the 341 and the 354 so theoretically, the 354 crank should fit in the 341. BUT. The 341 has a 3.7812” stroke and the 354 has a 3.625” stroke, which would effectively de-stroke the 341 down to a 325.
