My combo; 367/ @11/1/ alloy heads/ small cam/ 4-speed/3.55s @3650 pounds with me in it.
She will annihilate any size street tires that you can fit into the stock tubs, thru two gears for sure, and mine will go well into Third. Sliding around turns is a blast.
Never had a 383, but in 1970, My 340 Swinger annihilated them as installed in Bs; both engines stock. Just two caveats;1) never start from a dead stop, the Swinger just boiled the hides. and 2) shut down at the top of third gear . With 3.55s the 340 ran out of steam at 85/90 mph, and when going into 4th, it was all done. Mine only managed
98mph on those E70-14s. @3330 pounds/me in it..
So I vote 360, cuz outfitted as above, she goes 93 in the Eighth, still with 3.55s, after all these years ................ And besides, the hi-compression 360 can make phenomenal fuel mileage, and mine has always run on 87E10 since 1999
383s have shortest stroke of all Mopars. They are built to rev. Cam it up and run the gears and fine, have a blast. But with the cost of gas rising weekly, the handwriting is on the wall.
