Re: D/Dart in Stock
John (dart4forte),
No doubt, the 273 is a potent little unit, and durable too. We ran ours for
3 years, and never broke anything. but, those damn head gaskets would blow out every dozen races or so. Only 4 head bolts per cylinder.
Just saying, that trying to run a 273 at 275 hp against a 72'/73' 340 or
74' 360 would be a tough task enough. Too many cubes to deal with, and the later engines have bigger-valve heads.
D-Dart info. 1966, the D/Stock class break was 10.60 - 11.29 wt/hp factor. The car was specifically built for D/Stock, yet the car is listed from the factory with a Code; Super Stock Package. The 2-door sedan is listed with a 10.71 factor. Yet, the boneheads at NHRA list the car as a
possible convertible-car also. A heavier car with an 11.11 rating.
Why you ask. I don't know. Why in the hell would Dodge build a heavier car to fit in the same class (10.60 - 11.29). Call Edith Bunker at
NHRA, and ask her.
It would be like building a 68' Hemi Dart with a convertible, and fit it to be in the same class. Do you think the Mopar guys with all their tech brains
would make that kind of mistake? NO.
Year 1966. Barry and Ernie Musser of Pennsylvannia were tearing up the D/Stock class all over the place with their 61' Corvette 283/270Hp
dual-quad car. Running 12.90's. But, got beat at the 66' Winternationals
(February 66') by Dave Kempton. Running a 62' Plymouth which ran
in C/SA, running 13.08.
