I just picked up a 1955 F100 with a GM powerplant. I looked into getting the Holley SysteMAX 425hp kit for the top end. Anyone have experience with this and is there a good place i could pick one up. The bottom end of the motor is pretty much stock, would I be ok running this kit for a little while untill I get a rotating assembly kit for it. I will post some pics of it in another post.
Thanks
Eddie
Is your suspension & brakes up to that kind of power?
