4L80e conversion

[RedHeartbeat]

Well, ordered the flywheel parts for the 80e conversion today. I guess that makes me commited.

12551367 flywheel
12563533 (6) bolts
12563532 spacer
Precision 447 U-joint (1.188 & 1.125 diam caps. See later posts for more details.)
Precision 492-10 U-joint straps and bolts

The flywheel is flat and has 6 holes to match up to the stock convertor
The bolts are longer for the spacer
The spacer goes between the flywheel and the crankshaft

All the GM parts were bought through CrateEngineDepot, best price I could find on short notice.

I'll be able to make that harness for you.

All my parts just came in, well they are scheduled to show up today.

Driveshaft?
Cooling lines?
Re-pin connector?
Tuning?
All I can think of.

Awesome, Allen! What do I need to do to the tune to make it work? Driveshaft will be shortened and the slip yoke removed. My trans uses the bolton u-joint and I have two piece driveshaft so that won't be too pricey of a mod. The crossmember will be interesting.

Not sure of the mileage. Came out of a 97 farm truck that was beat to hell. Cost me my life savings, $200. plus driving 200 miles round trip to pick it up. Picked it up off of Craig's list.

It wouldn't suprise me if you got 2-3 years use out of it without any upgrades.

I'll have to send you a file to overlay on the current file, then the pcm can control the trans.
Say goodbye to rebuilding transmissions, good choice,

Thanks. At about 40 lbs it's definitely overkill but 6 x 1/2" plate almost 4 ft long gets heavy in a hurry. My poor little 110v MIG welder worked its butt off to put a decent weld on there. The thing is only rated to work well for up to 3/16" plate. The angle iron was 3 x 3 x 3/16". There is plenty of rigidity in the design. The new crossmember isn't much heavier than the previous design that I had made for the 60e to go over the cats.
