I'm not absolutely sure, but I think so. The front motor plates are interchangeable, and since the cover mounts the the front of that I think they are compatible. The only thing I'm not sure about is if the harmonic balancer oil seal matches.

I can look at my '62 261 and my '55 302 when I get home and see if there is any difference.

1950 Chevy pickup with '62 261, 4 speed.
