Good work Ferm! Billy Mac

Next update.

I'm making a little progress, BUT THIS THING IS KICKING MY ***!! I have spent the past 2 days fabbing the motor mounts and welding em up. The passenger side one is done, but the drivers side warped some from welding. So I have to straighten it some in the press, and weld the last brace into it. Next I'm going to re-inforce the trans crossmember and fix it where I modified it in the past for a GEAR VENDOR install that I took out. That ALLISON is quite a bit heavier than my 4L80E was and the crossmember seems to flex more than I would like with the weight on it. I also am going to have to modify the lower oil pan on the passenger side. GM changed the front diff mount on the later trucks so they could put the kick-out on the side of the oil pan for extra capacity. That kick-out hits the lower mount for the front diff on mine, so I'm going to cut and weld a plate in like Bigley did on his rather than change out the mount for the diff. I dropped the pan earlier before making the mounts and installed the diff to make sure it all would clear, and I had good clearance on it.

I also installed some limiters inside of my factory rubber mounts so the engine can't move as far since it is so tight in there. I'm hoping to finish the drivers mount, trans crossmember, and get the oil pan cut-out made tommorrow. I may take it to a local welder and have him tig it so that I don't have to worry about any leaks in the pan instead of migging it myself. If I can get that done then I'm going to go run some more parts down MONDAY and take a break from it for the day. Then start on the engine and tranny with what I'm going to do to them. I know it needs a FPR on the CP3 as it loped like a cammed big block at idle before, and I found a FORD relay for $13 to fix the glow plug controller with already. I will probably also do head gaskets as I see some signs of leakage around the passenger rear side of the head in between the block and head, and do the injector cups while I'm there.

I'm still up in the air though on the injectors. They currently have roughly 130K on em, but it had ZERO smoking before. The balance rates were less than .5 on 6 and 2 were at 2.5(one positive and one negative). I also plan on a KENNEDY lift pump, EFILIVE(found out the new AUTOCAL will only be for one ECM/TCM combo with no expansion to a second ECM or TCM incase one fails), and an adjusteable boost valve. Also I found a pre bent 4" exhaust that will fit my SUBURBAN so I don't have to modify a truck exhaust to fit. And swap out my 4.10's for some 3.42's, and replace my CV boots.

No pics tonight, been working and getting so greasy I didn't want to mess up my camera.

Got the motor mounts done today, finished up my tranny crossmember and modified the oil pan. Got the engine sitting in there and with it's weight on the mounts.

Heres my finished motor mounts.


Passenger side installed in the truck.


Drivers side installed.


Before installing the mounts I had to take my BFH and flatten out part of the mount clamshell where the motor mount bolt was close and also added in some 1/4" plate to act as limiters to reduce engine movement. The red circle is where I had to flatten the edge off. The blue arrow shows where I added my limiters(theres one in the bottom as well).


Oil pan clearance with it all together.


No turning back now. You can see I had to take a good bit out of the passenger side of the lower pan to clear the diff mount.


And the finished pan after welding, grinding, pressure testing, and paint.

Long since got rid of it. GEAR VENDORS took it back and refunded my money for it. Never could get it to work without driveline vibrations, and after 4 months of fighting it I returned it. Just something about the combo wouldn't work and made a HORRIBLE driveline resonance that would shake the rear view mirror off the windshield.

have you seen the new 6 speed auto that TCI has? Its got me interested for the blue truck
