Trans/t-case swap: 350/203 to 465/205 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Matt72blaze · 09-30-2007, 04:30 PM

Hey guys,
Newb here. I just picked up a '72 Blazer with a th350/203 and I'm about to pull the trigger on a 265/203 setup.

My questions:

1) Will I be able to use the same driveshaft? Or really, what's the length difference in the 2?

2) I'm guessing I'll need a different crossmember for the 265/205?

3) Some clutch/flywheel recommendations?

4) Can this be converted to a hydraulic clutch?

5) What other odds & ends parts will I need?

6) Any Portland guys want to have a R&R get together to put this in????? I'll buy the beer/dogs/burgers?????

Oh yea, here's a couple shots of it, I figure it's not too bad for $800

:

and

little rough in the back
