Carb for 408

With the street demon I can attest to excellent idle, throtlle response, crispness, acceleration, wot etc on the street in general (and strip after exploring the limits of tuning) You will have to tune it period, even just for the street. But it is cheap, just buy the tuning kit and work methodically on tuning it and you likely will be set. Or go with one of the off the shelf mid priced Holley (or variants) but expect to tune it for you setup. Or go all out like others have advised, and likely not have to mess with it much at all. (I have no experience with those so have nothing to say pro/con) Others here far more knowledgeable. I have run the entry priced 750 street demon and now have a mid priced AED 750 on my stroker setup and have had to tune for my setup on my own. You will need to tune either route, maybe a little, maybe quite a bit on the first two options.
