it was said before, and i have to agree
there is no replacement for displacement.
but you can get a SB over 400 cubes now.
the truth of the matter is, it's "whatever you want"
i have both. a bone stock 340 4 speed challenger. i drove that from
NJ to the Nats last year. awesome car to drive.
i also have a 440, indy ez-head, 4 speed challenger. that car, i wouldn't
drive to the nats from NJ. i'd have to buy an oil company
now let me tell you, that car IS awesome to drive too.
i say it's best to have one of each, for whatever mood your in
