question of the day! ??
Here, I'll be serious. I hit high 12's with a .030 over 360, stock crank, stock rods, stock 340 J-heads, 750 Holley on a dual plane intake, .484 lift hydraulic cam. It had 9.1 compression. Pistons were 135 dollar cheapest on the market. I had 1000 dollars into the motor (and that included buying the 360 for 25 bucks). It was backed by a stock 727 and a TCI street converter. My car weighed 3200 lbs. I drove it 1 hour to the track, raced it as I drove it. NO open headers, using normal pump gas, and DOT tires. If I did a build like yours, I'd say anything less than mid - 11's is garbage.
