I had one in a 289 HiPo back in the 70-80s, ya a while ago.
Dual Quads, Tunnel Ram, 5 something gears, turned in low 12s, sometimes.
They used to be the only way to go for a Ford.
Why are YOU choosing Crower ?
Did you contact their Customer Service and get info or a Cam choice ?
Comp Cams run well in Fords too, my latest Cam is a high lift, short duration bump stick that wil increase the low end torque and mid range HP, in a 5.0L V-8 that is.
Luck on your choices
