Mine was mostly just a simple swap. Leave the front of the truck on and plenum off. No exhaust bolts broke thanks to a good soak. Very worth while swap, better MPG and the L9h has some good power.

There is a good deal on a 1K mile L9H for 3500 if interested in Rochester NY .

Link?

Thanks.

Weird that someone would put an engine in then immediately take it out though.

That's awesome. So nothing on the front clip has to be pulled at all?

Si.

Just pull the fans and slip a piece of plywood or heavy cardboard in to protect the rad in case it gets away from you. You separate the block from the trans, come up and forward a little, rotate it, then forward more, then up and out.

If it's in the budget, I would. Nothing crazy, though. 5-6 hundred RPM makes a big difference, even on a stock motor. If camming, a looser converter may be even more helpful dependent upon that cam. There are a lot of factors that you have to honestly weigh, though.

Do you tow? How much weight?

I will be towing, yes. Not sure on weight yet, son is just getting to an age where we can do stuff like camping and/or boating.

I was referring to ZL1 torque converter. It stalls around 2200 and they're built tough.
