Been a while...
The trucks been running the built engine for a while now. Currently in the process of finishing swapping in a 4l80E - even a well built 4l70 just isn't strong enough.
Last year the engine got a stout billet girdle so the '80 is the last mechanical piece before I turn the wick up. All the remaining parts to install the methanol fuel system are ordered. Once this is installed the boost goes from 11 on pump gas to 20 (initially).
It been a wild ride getting to where the project is at.
There is a newer public forum
4200 specifically to support the 4200, swaps, and builds.
