Manual 465 to 90v20 Burb q's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jsfucttruck · 01-17-2018, 12:25 PM

So my friend wants to swap manual clutch setup, 465/205 into his 90 3/4 4x4 burb with a 400 and vss. I told him that I would love to help, but I have never done this swap. I have done the hydro swap and it was not too bad.

I am thinking the clutch linkage bracket could be the most pita thing to do. Any tips or pointers?I

Pretty sure the square body still had mechanical linkage in 90. Find a truck with all the goodies under the dash and install.
what's going to happen to the existing transmission and t-case?

I have that bracket. Let me find it and I can get some measurements for you. I don't think it would be hard to make from scratch.

I appreciate it.

I have
465/205 early style
Pedal Assembly and Z bar linkage from pedal
a 78 k20 frame with a bracket and linkage
Early Flat trans crossmember and t case skid

He is offering up a 74 K20 350/465/205,with a Dana 44/14bff that runs and drives as a payment with current reg.

I misunderstood, I thought you were missing the bracket. When you said it's going to be the worst part of the swap, you meant locating the bracket on the new frame?

85 is first year of the hydro clutch.

I have a bracket. I meant getting the bracket on. Would one have to lift the body off the frame a bit to drill the mounting holes?

I think the first yr for Hydro clutch for 83-84. I used a dually one as a donor for another swap. It was easier without the linkage.

The trans has no reverse. Not sure.

They would work fine if you ran the factory hydraulic clutch setup for that truck.

Jsfucttruck · 03-18-2018, 10:28 PM

Correct. He doesn't have the cash for it.

I found a whole 88 k5 donor, but he opted out.

He pays my time, so I let him decide. I tried to explain all the benefits. The blazer even had a tilt column and bench seat. It was mechanically sound with a rotten body. Guy was asking $1500. Even passed smog.

The owner said the headers had holes in them so he had planned to change them out.

Manifolds are on order.
