Need engine in my Elky...........

[brownie]

Guys, new to this site as well as to the whole rebuild/restore scene. Was hoping to get some advice regarding my 1980 El Camino. The car is in superb condition but needs a motor. I am kicking some ideas around but could use advice from people who know alot more than me. I don't need a racer, nor power for a daily driver. This will be my Sunday stroller and won't clock too many miles. Want something reliable but has some pop. Any advice on small vs big block given my goals? What about size? Sorry for the lack of info/knowledge. Any replies would be greatly appreciated. Thanks!
