ANYONE RUNNING A COMP CAM XE262 IN A 340?

You already have the cam.
Some of the most experienced guys out there already gave good advice.
A lot of guys want to recommend bigger cams, which just pushes the power to a higher rpm, which pushes it to a higher roadspeed.
With 3.23s and your stated useage, you neither need nor want that.
Yur gonna love that cam.
