blah blah blah,,,, a 440 in a dart will beat the drum out of an equally preped 340. A mild 383 in a 3800lb b-body w/ 3.91 gears will run mid 13's at best. The same 440 build will have you well into the 12's. Have had both and done both. I'd NEVER do a SB or 383 in a B-body. Even if it came w/ a "400hp" SB.




400hp SB? Like a Chebbie?
A. If you can get past the TRACTION PROBLEMS.
B. Everybody knows that a "mild" 383 and a 12sec 440 are two dissimilar motors.
C. It's GOOD that you have "stepped up" to a 500 cube - 440 based combo for your 70' Charger. Definitely NOT putting it down and it does run really HARD. If I had a CHOICE for that body style and car weight, I would setup the SAME
way and maybe add a few more pony-inducing items on it!!
D. 440 Darts were/are kinda hard to hook, without traction aids, so I don't think a 340 would have problems with it from the tree. It may be close after the 660 but 340's ARE capable of handing 440's a beatdown. FWIW, I DID get
by a few strong 340's and the same ones even whooped upon some 383's. Never knocked the "smaller" motor since I didn't know what they were carrying!
E. with ya on the SB or 383 in a B-Body,
But I'd chance a 383 in a "stripper" B-chassis or
a good A-body. Hands down, 340's are BEST (ok, dustergirl, you can stop jumpin' ) in the A-Body for street/strip.
3800lbs is kinda heavy for a 383 to push around, I would go no higher than 3500-3600 (incl. driver) absoulute! 3800lbs, is right for a "warm" 440. Just my own opinions said out loud!!






again a 440 any-body will walk a 340 any-body. I said it outloud.
$ for $ I'll give you 2 lights. both can be fast however if you are starting from square 1 and one guy/gal has a 440 mill and one has a 340 and both spend the same amount of money/buy the same parts...the 440 will ALWAYS win. (1/4 mile anyway)
