Prewitt Racing

5.1L

Everyone's been talking about them for years. Now Prewitt Racing  produces an affordable stroker for the Ford "Mod Motor". Based on a 3.625 bore in an iron block and an offset ground, 3.750 stroke crankshaft the Prewitt Racing "Street Fighter" delivers 310 cubic inches. That's 29 cubic inches more than the stock 281!

Can you say "torque"?
