Does anyone have a link to a site with the bolt pattern dimensions listed. Or rear of block dimensions. I'm looking to make an adapter for a GM tranny to a non-GM engine. So, I need the GM info.

I know somone knows where to find it. I've only found MOPAR stuff so far.

Thanks,
Nick

 

what are u adapting the gm tranny to ?..

 

Contact the usual tranny supply companies. There are a lot of adapters out there to bolt jsut about anything to anything. Lots of "specialty" websites that handle specific conversions, too. Even if it's a weekend warrior who just got a bug up his butt and decided to do something "different" they're usually great guys to go to for information.

 

First, let me say, I am a diehard GM fan. Always will be. All my vehicles up to now have been GM. Unitil, I bought a DSM. So with that.........
I'm working on an adapter to mate a GM automatic to Mitsubishi's legendary 4G63 4cyl. Now before you scoff at my senseless idea, I'm already in the process on installing a 70 455 in a 1990 Eclipse while changing it from AWD to RWD. The Mitsubishi/GM combo is for my brothers car.

Anyhow, thanks for the input, but I have yet to find anyone other that Buschur Racing in Ohio that sells such an adapter. It's over $500. He sells a complete kit for $4000 to mount a 4G63 4cyl in a Chrylser Conquest or Mitsubishi Starion. Wayy too expensive. Now you see why I'm looking to make my own.

Thanks,
Nick

 

Go to a junkyard and pick up a GM bellhousing..shouldn't cost more than $10
All the GM 4.3 V6, inline 6, and V8 up to the LS1 use the same bolt pattern.

 

Well, for that matter, I've got the GM tranny setting in my shop. I could measure it, but then there's potential error in that. Thus, why I'm looking for link to a bluerprint or "verified" measurements of the bolt pattern.

Here is a good example of a what I'm looking for, only it's Mopar.

OK, I take it back. Maybe they don't make adapters for EVERYTHING.

I think you're in "DIY" land with that swap.
