    Hi Guys,
    Please post your Cadillac engine combos (engine displacement and modifications, approx horsepower, vehicle weight w/ driver, transmission type, all the details) along with your best E.T.s / MPH with that combo.  NO DISCUSSION PLEASE in this thread, its purpose is to give others a clear idea of what stuff it takes to go a certain E.T. and MPH.

    Mine was  :backinmyday: a '83 Bonneville with a stock '74 500 and Cad th400. I did have a Edelbrock intake and a recurve kit in the distributor and dual exhaust. The rear gears are 2.29s. I only made one pass down Epping dragstrip last year and I spun the tires awfully right off the line but I still ran a 14.8 et. I have no doubt it could have run low 14s or maybe even better with a little practice.  :thumbup:

          Never tuned engine. Tall truck.  Pain in the ass to climb in engine bay to work on it.   Had other things going.......plugs and exhaust were allways black
      Allways had some wheel hop with the Cal-Trac bars. NHRA Dodge truck racers said I had way to much frame flex and wheelbase length for a 60 ft time.  I did have  1.84s but could have been much better.
          Best times were 12.61s @ 108 mph on a cool day   13.00 flat @ 104  on a hot day.   
          Engine has been on engine stand all year waiting for updates.  Would like to have put engine in my  Coup   Instant 12.40s because of wheel-base alone :thumbup:

      Have a 1975 Dodge swb pick-up with a basically bone stock 472.No bore/stroke job.The engine is a 1970 vintage
    with the 76 cc heads which have I've opened and smoothed the ports and combustion chamber.The rotating is balanced.It has stock intake and exhaust manifolds and a mild Lunati cam with a 125 hp nitrous set-up.The tranny is the Cadillac long tail TH-400.The rear end is out of a 1980 Dodge Ram Charger,limited slip with 2.94 gears. Weighs 3300-3500 lbs.
    (It's a daily driver) It's best times without the squeezes is 12.56@ about 100mph,with the squeeze on after the revs get a little past 2,000 rpm's and holding it all the to the end it ran 11.82 @ 114 mph.That's with 10.5x29 slicks.
    It sure pisses off the youngsters with their Camaro's and Mustangs when I smoke their butts.
