The 262/270 is fairly mild for a 460 engine, but will make excellent torque. I'm running one of the xtreme 4x4's in a '83 f100 /460, and have no complaints. I believe it's a 278 /288 .572/.580. Lots of mid-range and top end with early ported heads. The compression on our motor is 9.5:1. Also has 2.25/2.76 valves. The low end is not as strong as it would be with the 262/270, but it will still fry tires at will.
I selected the smallest 4X4 Extreme Energy cam from Comp for the 385 series engine,I believe the cam number is 231-?,with some cylinder head mods,Performer intake,450 cfm Holley,headers and the good sense basics I am very pleased with everyday performance and the USABLE everyday power it provides.
