It's a 400 ci Vortec Chevrolet crate engine.
5 sp manual behind it.
So with a tare weight of around three tons ( haven't had chance to get it over a weighbridge lately, hopefully over the next few weeks,) it should have lots of grunt way down, and with a higher ratio diff still be a good cruiser.
I've never built a project like this before, everything else we've done has been familiar, you know the parameters; here I'm on a learning curve, so I know there will be a few tweaks to make, but we'll work those out as they arise.

I've never been involved with an engine like this before either . . . I mean; there's no carburettor, and no ignition system that I'm familiar with!
I s'pose I'll work it out.
But I'm taking out 'Roadside Assistance' insurance.
