big block would be ideal, but then i would sacrifice handling and it would be more expensive. I'm probably gonna stick with a 318/340/360(whichever i can get for the most reasonable price).
I'd say best bang for your buck is a 360. lots of options for you there. Big block is quite a bit more expensive to do. I know that some fabo members disagrea with me on that. But coming from someone that has done a BB, I know how much less a SB install would have cost.
