I have to choose between two C4 trannys. One has a more rounded bellhousing, the body flares up to the bellhousing; it has the dip stick in the pan, and has a tag:

PEA C
289 6L 28

Is there actually any difference between C4s?
Thanks,
Dave

later model c-4's have a larger imput shaft, which makes them stronger.

All you really care about is that the input shaft has 26 splines and that the bell housing will fit the block that you intend to use. Othewise the builder will use the "good" parts.

Another C4 question is has anybody mated one to a FE block? Now I'm switching to a 390 now and was wondering if I could use the C4 that I have.The C4 is built heavy duty for drag racing .

You can buy a FE bellhousing to fit a C4 case from JPT transmissions in Michigan. I don`t have the ph. #, but I`m sure Alex does.
