What would you do? Slant performance
What? Estimating an as raced wt. of 2770#, and a rough est of 220hp@the wheels putsthat thing in the low 13's @ 100mph. I guess all those 240hp 5.0'stang's turning mid 13's in the '90's w/3.73's and hoosier DOTquicktimes were secretly using mag-propulsion?
Case in point: Back in 1962, I had a friend who had a '60 Valiant 225 (cast iron block) that he played around with. The modifications he had made included the addition of some second-hand HyperPak parts he had acquired that included a HyperPak intake manifold and the Carter AFB that the factory recommended for that application, a pair of the cast iron HyperPak exhaust "headers," the hyper pack cam and lifters, and a head that was milled .100", plus some stronger valve springs.
He usually ran it without mufflers. It was equipped with a 3.91 and a three-on-the-tree, manual transmission. I remember something about his having up-graded the clutch, at one time.
Over a three-year period of trying to get the most out of it, it finally ran a best e.t. of 15-flat at 92+mph.
One of the current FABO members (Mopar305kid?) purpose-built a naturally-aspirated 225-powered 1968 Dart for the expressed-purpose of seeing how fast/quick it would go, He didn't use any "heroic measures" but it pretty-much had all the usual bells and whistles such as a 4bbl carb, headers, a deep-geared, limited-slip rear end, a "full-race" cam and valve-train, modified ignition, a ported, milled head, with big valves, a high-stall converter in the 904, racing shocks, and drag slicks.
His best-ever e.t. after much experimentation, was 14-flat at something less than 100 MPH.
The car weighed approximately 2,900 pounds...
Mad Max (on FABO) has gone a lot faster and quicker than that, but, he has an unusual-performing car that has been the recipient of some serious weight-reduction over a period of time... I think his car weighs somewhere around 2,300-pounds... and, it HOOKS!
Anybody can take weight out of a car, but the Mad Max car has taken it to a whole, new level...:cheers:
I think that Johnny Dart is not too far off the mark. We had a '62 Lancer in '63 that had a 225 with a HyperPak manifold and carb, with a .100" milled head a 3:55 gear and a HyperPak cam, running through a stock 225 exhaust system, and it ran 15.88 at 88 MPH. The cast iron HyperPak manifolds had serious interference problems (wouldn't work) with the 904 starter solenoid...
That isn't very fast, but remember, these cars usually start out in the mid 18-second range.
Knock 2 1/2-seconds off any car's quarter-mile time and it won't "feel" like the same car...
