13's, stock '71 318 short block.

My Duster with a bone stock '79 - 318 and LU 904 with 3.21 suregrip on stock tires ran a 15.14 with nothing more than bolt on's and a small Crane cam. 272/284 (216/228 @ 050 ) .454/.480 lift on a 112 c-line, LD4B, 625 Carter, MP unsilnced air cleaner, hooker headers into a Jegs 2-1/2 exhaust to the bumper, electric fan.

no shift kit, no porting, OE valves in the stock head, stock pistons, stock stock stock

Did you have any kind of stall with that combo. I am gonna run a '74 318 stock bottom with 97XXX miles. Plans are cam, intake, carb, maybe a set of 302s if I can find a set. Gonna run 3.55s, 2500ish stall, shift kit, drag radials, and a set of cheaper headers. If I can I might try to clean up the 302s with a little porting. All in a 72 Duster.
