I have a 396 in an 85 Chevy pickup. Before that it was in a 56 Chevy 2 ton truck. Before that it was in a 70 3/4 ton Chevy pickup I bought at the local junk yard and drove for a couple years. Before that I don't know what it was in but I think it is a 67 engine. I have had it over 25 years but not a great many miles on it, or at least I haven't put that many on it.
