Cruise friendly low 12's with a 340 Dart

I use Mancini for the kits i use. I have my shop do the balancing, and i clean,a ssemble, and run them. Costs will vary, I really like Rumbles advice of "do the shopping yourself." For a mild 4" engine, the RPM Air Gap, and a Holly 770 Stret Avenger Vacuum Sec. carb is what I spec. With a small port head (any iron, ported or not, and stock port Edelbrocks) a cam of 250°@.050 will out pull a 440 from 1500rpm. So OD and gearing becomes irrelevant. using the moparts calculator, the engine that just cost $5800 would propel your car at 3100 pounds to 11.70s. That's a mild 422(340+.060 and 4" stroke) with ported (by me) ion heads and a small-for-the-stroke hydraulic (248° @ .050 int, 258° @ .050 exh) cam. On pump 91, and with 3.23 gears. With stock heads and off the shelf pistons, you can do the same thing for about $900 less. And that's carb to oil pan. New carb, old oil pan ;)
