2.8 V6 bellhousing bolt pattern dimensions

[79stingman]

Hi,
I am going to make an adapter to mate the 2.8 V6 to a TH350 with the V8 Bellhousing. Would someone have a diagram of the rear of a 2.8 V6 showing the dimensions of the bolt holes and the centerline of the crankshaft etc.? I think there is one in the Chevrolet power book part # 24502488 on page 169??

Thanks,
Ryan

This is for the 3.5 block, but it's the same pattern...

You can buy one for $65 at Speedway.

I am almost positive that the crank is in the same position, but here is the diagram out of the Power Manual if you want to verfiy...

It's only $65 and is what you are wanting and proven and perfect.

I can only imagine the quality of the rest of this nightmare!!

A Turbo350 behind a small V6. Can I ask why when there were a million or so 700R4's behind the 60 Degree V6, Iron Duke, 3800 and Many others which will all fit?

i guess so there's room to step up to the TH400? or even a powerglide? i can't imagine the 660 that would require a turbo350 let alone the monsters that would need a 400 or PG...

Lol,
Ive got a old 1979 chevrolet monza with a blown 4 cylinder engine and I am going to replace it with a 2.8 v6. I do not want to go through the hassle of installing a different transmission, So I am just going to make an adapter.

oh.... well at least the 2.8 will be a little more fun. could step up to a 3.4 later too...

my dad had one a LONG time ago, fun little cars...

Does teh car have the 2.3L or 2.5L?

If it is the 2.5L you wont have a problem bolting in a 60 Degree V6 to the current transmission
