47-55.1 Advise from LS swappers.

So, on my long-term 54, my plans have always been to swap in a Vortec 4200. Well, I sold my 04 Trailblazer last week to a young guy that did some insulating work for me. I've owned the Trailblazer since 05 and it was a great running vehicle for the last 200,000 + miles.

Anyhow, I'm looking to purge some of my remaining Vortec 4200 parts that I've collected.

First off, is the AR5/MA5 transmission worth bolting to an LS with the Fabbott kit? I already have
the AR5 and a LS 4l60e, which I bought for the 2wd tailshaft.

I also have a P10 ecm and an E67 ecm that are for the 4200, but are they worth keeping for the LS? The P10 is capable or controlling a 4l60e and it has an internal TAC control. I know the E67 needs a 58 tooth reluctor, but is it worth reflashing?

Last question, I can find Suburbans and old service vans for cheap, pretty much everywhere. Am I better off with a complete vehicle?
