What car is the engine going in? I'm guessing an A body? If so I'd go for the 408 as a SB is WAY easier to work on than a BB in a A body. I have both, BB car is quicker, but more of a pain to work on.
I agree with that DusterKid. I tell my son the bigblock A-body is a young mans car since its hard to work on in some area's and the bigblock B-body is an old mans car since it has more room. As for the most part my 63 Sport Fury has more room to work on it then my sons 400 Dart does. Ron
I'm gonna roll with Dusterkid and 383man on this one, I've built and owned multiple bb abodies with both underchassis and fender well Headers, fenderwells are nice for maintenance but unsightly for street exhaust and TTI underchassis are nice Headers to look at but jeez...so...if it's a coin toss on 408 vs 406 I'm going small block, which exactly the decision I made on the 67 Dart I'm building.
