It's pretty easy to run 11's in a narrow A body, one of my friends initially threw his together out of spare parts and ran 12.0's. It had a rebuilt LA 360 with KB 107's, MP292/.508 cam, 1 5/8" hooker semi fenderwells, stock 1.88 heads, stock iron intake and TQ, 998 with cheetah VB and stock converter, 4.88's and 26" slicks on 14" wheels.

It's been evolving the past 12 years and runs 5.70's in the 1/8 now but it made it there a piece at a time.

On the initial build 2.02 valves, a LD340 manifold and 8" converter dropped it to 11.30's, W2's, M1 single plane, MP312/.590, 1 3/4" fenderwells and 28" slicks dropped it to 10.50's.
