Nope, it wasn't me. But someone on here did say something like that. After thrashing (trashing?) 301 Pontiacs for a few years, I wouldn't be concerned about the bottom ends in the iron dukes. Believe it or not, they use a lot of the same parts.
85 Camaro/Tech4 has been on my to-do list for a while. It's better than the earlier ones.
