Horsepower

2 barrel pistons, 920 heads, OEM intake and Edelbrock 600 cfm, Headers, and an Isky E4 cam, 340 valve springs, and good machine work made 260+ HP built by someone who knows what they are doing. You won't know what hp you have till you run it at the track or put it on a dyno. It really does not matter. Enjoy!
