In the 14s bracket id assume or a somewhere in the 13s mark if you went crazy. (big$$$)

I mentioned this once before. A story my uncle told me who is a an engine reconditioner. They built and a15 for this guy. He had custom forged pistons and rods. Good rod bolts, headstuds and head gasket. Shotpeened crank, o-ringed block and my cousin did the headwork. Massive valves, double valve springs and alot of hours playing around with the flow numbers. Supercharged, fuel injected with a carefully thought out cam. To end the story it ran a 12.7/ (sorry cant remember mile an hour) Lots of dollars though but i think this proves the A-series worthy.
