I don't think that 5.7 is going to be all aluminum. Perhaps aluminum heads? But, maybe something special going on there. Anyway, an LS1 and T-56 is an amazing power train for an old pickup!! Hard to beat. If that guy was in AZ, I'd do whatever it took to scrounge up $1,500 before he finds another buyer. If the car is in decent condition and you have the time & space, you could recoup most, if not all, of your expense by parting the red of it out.

How many miles are on the car? How does it run and drive now? It's hard to say what the engine and transmission are worth. I think that if it's not super high mileage and runs well, the engine and transmission are likely worth his asking price. If you need to part with your M21, PM me with info, if you'd like. I'm looking for a M21 for my '68 GMC, to put behind my new big block.

Good luck!
