11 second smallblock...how would you build it?

Forget stock heads and putting money in them, buy a set of RHS or Iron Ram heads from Hughes Engines. Dollars for horsepower they're better and when you port an old head and throw some real compression in your'e running a good chance of cracking them. Solid lift cams are good, solid roller is better but costly. Your'e going to have to spin that motor so over build it to survive 7000 rpm but should get away with 6000. Make the car as light as possible and suspension, weight transfer is critical if you want to launch with some power and not blow the tires loose. Pump gas will definetly be questionable. Good Luck
