Hello

has anyone out there have any experience with the Extreme 4x4 camshaft for the 385 series engines.

I am interested in the 262/270 duration cam in my 1968 Merc truck.

Thanks,

Terry

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.

I swapped a Lunati Bracket Master II out for a CC extreme grind 210/218. After I finally found the tune, it was A LOT better than the Lunati. Yep, it was better up until it wiped a lobe at 1000 miles.

I think it was ground wrong. The warranty dept was good to work with and so far my 2nd new cam seems to be ok. Time will tell. The performance increase on my 8:5 460 was very nice. Good luck
