Looking for websites

[8GPLE7]

I'm in the market for a new car or, truck I should say. I'm thinking somewhere in the mid '80s and ealier. It's gonna be a daily driver but of course I'm going to build up another engine for it with my spare block, maybe stroke it but definitely make it FI. Does anyone here know of some good websites or forums for those year trucks. I don't know much about trucks, at least not like the g-body but I wanna learn.
Right now there is a 1979 SB chevy stepside that looks pretty good that I'm interested in. Any help on websites appreciated.

Thanks
