Thread: 315 hemi

Has anyone ever hotroded a 315 hemi? Can a person buy aftermaket parts for this engine? how much power you did you make?

Not much out there for the Dodge Hemi's, at least compared to the Chrysler's. I'd start with www.hothemiheads.com for info and parts. You can find a bit more on the Allpar site as well.

You can get a couple of different cam grinds from Nielson Vintage Racing Cams, 801-451-7745. Pistons from Ross. Couple of folks make U-Fab log manifolds for this and the Desoto Hemi's. I think that Dodge even offered the 315 Hemi with a dual-quad manifold, try watching ebay.

I bought a 1956 Dodge 500 new. It had a 315 c.i. hemi with a single four barrel, but a dual four barrel option was available. 260 advertised horsepower and something in excess of 330 ft. lbs. of torque at a comparatively low rpm, and 9.5 to 1 (I think) c.r.

These engines can definitely be made to run.

The engine was in a cheapie Coronet 2-door sedan and the only indication that anything was different about it was a little crossed flags emblem on the hood. The car caused feelings of great distress among 283 "power pack" owners, even with its sad one-shifting automatic transmission (it stayed in flat low gear until it dumped over into drive at seventy).

As Mark says, some guys are making log-type intakes for the smaller hemi engines, but I really don't know about aftermarket parts.
