Match Race ~ 1965 Valiant '273 Commando' vs. 1973 'Duster 340'

Fine-Tuned and Carburetor 'tweaked', still isn't getting under 15.00.

I know, my sister had a brand new one in 1973 with A/C.

With the A/C belt disconnected, and with around 3000 Miles on the Odometer, it could lay down nothing better than 15.10's @ 90 MPH

.......Okay, add 7" Slicks, and it probably would have hit 14.90's.

Please explain how the same components from a 73 340 (carb, intake, heads, and cam) were bolted on a STOCK 318 block (stock pistons, rods, crank, everything stock) with 3.21 gears and a stock 727 tranny and stock stall converter ran 14.41 at 96 mph??? In a '76 Dart Sport? The bigger bore/more cubes slow it up? Me and my brother threw it together and we both ran it at the dragstrip. I can't help it what your sisters car did, it doesn't speak for all of them. I know if we would have had a 340 short block instead of 318, we would have been knocking on 13's door, and maybe pulled a high 13's. But slow-joes (under achievers) are always at the strip and they think everyone else has "hidden" nitrious" or something. Sold that 76 Dart Sport about 17 years ago and its still running today..... with the same motor we threw together!
