ok so i have a 70 duster.. i have a stock 318 that i was gonna put in but i dont want it to be a complete slug.. i was wondering if a stock 318 with a good cam, air gap, good carb and a set of headers would run 12s with a 125-150 shot of nitrous.. or if the 318 could even handle that.. thank you the rear gear is 3.91.. un sure on the tire size..

How about finding a 360,and doing the same mods your going to do to the 318,with a decent converter,and the gear you already have(3.91's) it might touch the twelves..and its MUCH more rewarding running the number not having to spray:-D:-D

Normally I say use what ya got in the car allready, but here stoke 340 makes sense. Selling the 318 and roll the money over into a 360 for a nice jump in cubes (42) and lots more arm with it. That equals torque.

The 318 can do well, but being down on cubes is a tuff thing to overcome and doing it reliabley gets tuffer and tuffer the faster you go. I have seen a dude on the net run 11's with his 318 Duster. I don't remember what he did to do it though. Anyway, the faster you go, the more expensive it gets and if the engine is small, it gets more expensive to do and maintain.

Since the 318 has a short stroke, getting the power level up to where it needs to be for 11's will make the car less streetable (If your going to be there at all that is) and a bit nasty on the other components. Higher stall and gears will be needed adding to the stress of the engine and chassis. Weight is also another consideration.
