The Comp XE268H cam will work just fine in a stockish 383. Yes, you can hear it tapping away because of the fast ramp lobes, but it's no big deal. I ran the XE262H which is one step down from the 268, this was with stock heads and rockers and steel shim head gaskets. It was a tapper too, but I liked it. I now run a Hughes cam.

What type of exhaust/manifolds/headers, rear gears and transmission will you be running? That will make a difference on which cam is best to run.




Stock exhaust manifolds, stock 727, (I may go with a trans go kit) 323 gears, edelbrock 1407 carb (750 cfm)




The XE262H will have slightly more torque over the XE268H which will have slightly higher horse power over the 262. Personally I'd run the 262 with your combo. I ran the XE262H in my 383. It ran strong up to 5,700 RPM's. Slight noticeable idle. The 268 will work OK with high gears and low converter stall.
