Re: 1956 rear end ID

I ran that same rear end in my 57 panel with a seriously hot 327 in it. No dyno on the engine but with an Engle cam and 12.5 Jahns pistons with 202 heads and an early Corvette 2x4 intake it would pull the wheels on a hard launch. It would stay with 750 Honda street bikes and 500 series Mercedes in stop light to stop light go's. No problem with the rear end but I blew the clutch racing the Mercedes at lunch and my boss heard it blow and sent the wrecker after me. The thing only got 3mpg though.

I don't know what that truss is for but would expect that they carried heavy loads or did some hard driving with it at some time. If it isn't broke I wouldn't be in a rush to fix it but if it needs work I'd go with a 9 inch Ford rear and be done with it. I've decided to put one in my 48 after running Spicer rears for the past 40
