[Vwdiesel] GM V-8 diesels of the '80s

[Patrick Dolan]

I am no Chevy guy, but I think you will find that there are only two bolt patterns for 90+% of GM engines: Corporate large and copropate small.  The corporate large is for all big block and small block v8s, and small is for the V6s - and I think even some of the funny transverse V8 installations.  Most GM slushboxes come in both patterns, but some (4-80LE or whatever) are large only.  The 200 really was a disaster, but a TH350 or 700R4 will easily replace it.
