Hadn't know about that at the time, and Dan Stern does a lot for the Mopar A-body community, so I thought I'd send some cash his way.

Today's work: Putting in a new rear main seal (might as well, while the engine's out of the truck), and relocating the stock engine mounts one notch back so they'll let the LS sit in the stock location while clearing the A/C compressor. Oddly enough, the frame rails are already drilled for it, meaning I just had to move two tabs on the brake lines and drill new holes in the crossmember.

from back when they stamped everything for everything? I used to be amused with the swiss cheesed frame around the engine mounts.

or get the brackets from a 6 cyl truck and just bolt them in

[Matt Cramer]

What advantage would the 6 cylinder brackets have? I wonder if they'd help with my current problem.



The mounts bolt up to the adapter plates, but they're just not clearing the manifolds.

Took a look at it this morning, and it looks like I can just use a couple spacers / washers and make it fit.

The engine position, relative to the front/rear of the truck, was different on the 6 and 8 trucks from 67-72. The six sat further back. The six mounts were also used on the 63-66 trucks for both the six and V8.

(by "six" I mean the 230-250, not the 292, which has one mount forward and one back, and is really weird)

I wouldn't dismiss a grinder or BFH either. I wondered about a washer/spacer earlier when I saw the pictures. I can't see where the manifold hits? They took a torch and bent the frame on Trucks! LS into that series to clear the manifold.

The section of the bracket near where it bolts to the frame rail hits the manifold. Not a safe spot to grind on, but a BFH is an option.

YOu could get big block mounts...kind of pricey, but they clear big exhaust manifolds. They set the engine between the six and small block positions.

Your engine might be sitting on six mounts already.

what about sliding a 1/4" plate between the mount and the mill?

The frame rail they took a torch to and bent it down with a 12" crescent when it was cherry red I believe... seems cheaper than calling Kooks!

That's the plan, more or less. With a BFH as plan B.

Today I wired the engine up while it was sitting on a pallet and tested out the ECU and wiring harness. Things were going quite well until I got to the ignition test mode - I was trying to hear the faint click of a coil firing, but much to my surprise, there was still an ignitable air/fuel mixture in some of the cylinders! Ok, nothing damaged, but I didn't expect a kaboom when I turned the coils on!
