6.2/6.5 in a First Gen Blazer/ 4wd 67-72 Chevy?

[JohnyWard]

Any experience with these swaps? I am about to start this build and an looking for some last minute advice/ knowledge.

Project:: 1971 blazer 44/14ff, mil spec Jcode 6.2, nv4500, np208 with a dodge backhalf

Have no real input other than i cannot wait to see some progress pics. I threw around the idea of a 6.5turbo in my 1st gen for a while.

I think colbystevens has a 6.2 in his 2nd gen with a sm465.

I have a 6.2 on an '83 frame with a '73 body. The 6.2's use the same engine mount as the 350 - so I think the swap into that frame should be no big deal. wiring might need to be custom for your gauge set up.

Wow, Delay of all Delays!

So here it is in place:

and here are some of the transmission cross member you can probably see some of my concers:

^ with the camera prependicular to the yoke face of the front axle.

^ and from the just behind.
You can see the clearance was just barely there. Well the spacer I had in there between the stock crossmember (moved back about 2") and the transmission was a 2" x 3" .120 wall box tube. So I put in a 2" x 4" and picked up more. But there is only +/- .5" between the upper most parts of the TCase and the floor pan.

The extra inch also helped reduce the dirve shaft angles:

^ this was with the 3" spacer in.
Plus I ground down the rivets and removed on the upper TCase xmember seen on this photo:

So that's the up date. Next, fire the engine! I have never heard it run and it makes me a little nervous. Brakes: The MC and Hydroboost are from a 86 military truck and the ports are BEASTLY. plus I need to figure out where to plumb in a preassure reducing/ proportioning valve. And the Clutch.. Russell makes a fitting to convert the factory master/slave fittings to AN fittings. Very nice pieces.

Actually, Lets Backup a Little

So a quick pic recap:

I am trying to fit this into this:

And the best way I have found to do this from the pirate forums is to use second gen Blazer and it looks something like this:

These are 1987 chevy halfton motor mounts mounted in the front hole of the factory first gen mounts. I had to oblong them just a bit to match the on-center bolt spacing from the second gen chevy. The rear bolts of the mounts had to be drilled into the frame. I test fit the motor and it fits! So I drilled out the rest of the holes that I can reach with a drill and bolt it all together for hopefully the last time.
I am using all of the factory nv4500 bell housing and hydraulic clutch.

Looks good so far, nice work.

Very cool! I put a turbo'd 6.2 in my '67 C-30. Firing it up will be fun. Here's a video from the first day I got mine running for inspiration!
