what rwd trannys will boltup to a series I or II

[MikeRWK]

I'm planning on a swap using a s/c 3.8 and i need to know if any rwd trannies will boltup to the motor.

I believe that a camaro/firebird 4l60E will bolt up. Not sure about the S10 trans. The series I and series II have the 60 degree bolt pattern.

So would a 5 spd from a 2.8 or 3.4 boltup?

Yes, but you may need to machine the crank to accept a pilot bushing.

[MikeRWK]

I was thinking about that, have an idea of how much it would cost?

[MikeRWK]

Do these motors still have the holes on the side for motor mounts?

Mike, I've been searching the answer to this same question. I want to put one in a skylark but can't seem to find someone that knows for sure. Is the 4l60 tranny have the universal bolt pattern box or a chevy only pattern? I know the 3800 came in the Camaros but not supercharged so I know I can use one of those blocks but wonder if all the blocks have that same provision.

I know for sure that the early 3800's had provision for mounts on the side. That changed later on but I am not sure when. Sorry!
