I have a good 17.40 B body 440 combo- '75 440, generic cast pistons .200 in the hole, stock heads for the '75 w/2.08's & MP springs for the .509 around 85cc, TM7 with a 2"open spacer & 850 holley DP, MP .509 cam not degreed with a $19 timing chain, Hooker SC's IIRC 1 7/8 w/3" exhaust & Flowmasters, 727 w/12" converter and Cheetah reverse MVB, 2.94 open rear, L60 MT I treads on 10" centerlines.

Take all this and put it in a '70 Coronet R/T and it will get you into the 17's at around 80mph.

I knew it was pretty sick but didn't know how bad 'til he took it to the track.

Another good one was a early B body with a cross ram Hemi that ran 15.0's on race gas- I thumped that a few times with a all iron 360 in a '67 Valiant, only mods were a 280/.474 MP cam, 3310 holley on the stock intake and 3.91's- it was still going through 318 manifolds and was on street radials.
