12 Second N/A Slant 6?

It can be done, but not easily or cheaply. The hardest part is keeping it "street driver". I know you said N/A, but N2o would be the best way in my opinion. My 66 Cuda has a totally stock short block 170 , with a mild cam (.434 lift, 264 dur, 232 [email protected]) Milled head (39cc chambers) stock valves and 340 springs. Clifford headers, stock 1 bbl intake, modified to mount a 500 cfm 2bbl Holley carb, and nitrous fogger nozzles, MSD 6A ignition. 3,000 rpm converter, 3.91 SG 8 3/4 rear, and 8x23x13 slicks. Car weighs 3250 with driver, and runs low 13's in the quarter at about 100 mph.

My 66 Valiant is similar but has a 225 but with Offie intake and 390 Holley 4 bbl and 125 hp plate system (actually two 125 plates, but have never used the second stage, yet). This car has run low 13's also, and is capable of 12's but we have had some other issues, that have prevented a 12 sec run. This car was built for about $2,000 including buying the car, and it weighs just under 2700 lbs with driver, but does not have street equipment.
