Even though I don't have the funds to get started, I have decided anyway to start putting a plan together for the future in case I do ever decide to get myself a K5 and join the fun with everybody. Now I'm wondering what's the best motor to go with that offers me good power vs. economy. I'm at the moment thinking of a built-up 305 or a 350 small block. I'm thinking 305 first off because my grandma's '91 Caprice Classic has one, and that car's got plenty of power. I'm not looking for an engine that'll allow me to do burnouts by no means. Instead I'm wanting an engine that'll have tons of low-end and when I drive with a light-foot, still maybe get 17-20 mpg (wishful thinking I know). So look at the poll and tell me what my options are. Tranny will most likely be either an SM465 or 700r4 w/ full manual valvebody, with a 205 twin-stick case. EDIT - Turbo'd 6.2 is another option I'm seriously considering. Big blocks are out of the question for fuel economy reasons.
