Need An Upgrade Tranny SL6

I have never really heard anything good about TCI trannies.

If you are going to keep the slant and you want more tranny options then you need the adapter plate and crank spacer out of a mid 60's (I can't remember the exact years) dodge truck/van with a slant and a 727. It was a smallblock V8 tranny with a adapter plate for a slant. If you get the plate and crank spacer you can bolt any smallblock tranny (including a 518 ) to a slant. You may also be able to get a modified chevy powerglide to bolt up.
