I saw a post on the IFSJA website about an article on a 401 build in the May issue of Hot Rod IIRC. It can't be a May issue already can it? The cousin of the design and architecture between Buick and AMC/Jeep are wonderful:TU:
bjsoffroad (can't post links yet, I'm still too much of a noob.) Awesome site if you need random obscure parts like blank bed sides or floor pans. Just wish they had more driveline parts. oldbuickparts is also great.
