So how far do you drive? What body is it going in? Are you worried about gas mileage? What power band are you looking for? Do you have a suspensions set up to handle the different kind of power a bb vs sm block? What do your wheel wells look like? Are you talking light to light racing more than 1/8 or is 1/4 in the future? What does the rest of your build look like? Whats your budget?
