Well, I bought one.....

You call yours the Grenade 360 and I call my version the Junkyard 360. It is a 84 LA snow plow truck motor that is in the hillbilly dart waiting to be hooked up.
It is complete with a couple hundred thousand miles original bearings. I did have to change the oil pan and pick up to a car pan. I put a new timing chain in it and a fresh set of stock heads on it. It did have a Quadrajet on it but I will either use a holly or thermoquad.
