Can anyone tell me what changes have to be made to the drivetrain and the engine bay in order to put a '57 392 Hemi in a '68 Fastback Barracuda? Thanks!
I wanted to put a 354 in my brothers 67 Fastback Barracuda, but when I talked to people that had done it, it was more than I cared to do. The big Chrysler Hemis are big. Spacing the K member down, custom headers, the motor mount brackets are farther apart, but not as hard as one would think. The Mopar small block is a very close cousin. I'm getting close to putting a 57 Desoto 341 Hemi in the Barracuda. The Desoto Hemi's are almost a drop in. The motor mounting ears are the same and the block is 5/8 of an inch shorter which works out well since you need a 1 inch spacer to put the Hemi crank flange in the correct position to bolt up a modern transmission. The oil pan rails are the same width but short by the same 5/8 of an inch. A lot of mixing and matching to get good speed parts, but the short block and heads are bullet proof, no special parts required. I've always wanted an early Hemi in something. Not nearly as heavy as people make them out to be. Maybe this spring.
