      Good Idle. Give your 5.0 Pony a good sounding idle that is louder than stock, but is not overbearing or obnoxious.

      Will this cam work in my 94 mustang stock e7 heads with 1.7 roller rockers ? Do i have to upgrade to a high stall torque converter

      • The Comp Cams Stage 2 Xtreme Energy XE266HR Camshaft will be compatible with your setup. A high stall torque converter is not required, but will drastically improve performance.

      What all else would be needed for install with this cam as far as valve springs guides push rods timing chain gears lifters and such?

      • When installing the Comp Cams Stage 2 Xtreme Energy XE266HR Camshaft you will need new valve springs, and retainers. The push rods and lifters, timing chain and guide plates are not required, however it is a good idea to replace these as insurance while everything is apart.

      Is this a computer controlled cam?

      • Yes, this would be a computer controlled camshaft.

      My car is mostly stock with some gears and minor bolt ons. I heard that cams with a lift and duration as high as this will not work in a stock motor. Is that true or can this can be installed in a motor with stock heads and pistons?

      • This can be installed on a stock motor but these cams do require some additional parts to work properly on your Mustang. These cams will require steeper gears (3.27 to 3.73), throttle body, and an upgraded mass airflow. Without those modifications added to your Mustang, these cams would not be ideal for your Mustang.

      Will this product need any other parts or will it fit in the stock camshaft

      • This Comp Cams XE266HR Camshaft is designed for use in Mass Air equipped 1986-1995 5.0L V8 Mustangs with mild modifications such as 3.27 to 3.73 rear gears, a larger throttle body, and a mass air flow upgrade.

      Do I need to change my distributor gear to composite? its a 91 5.0 1 answer
      what is the lift 1 answer
      I have 24lb injectors, 76mm mass air, 75mm throttle body, 373 gears, performer intake manifold, and shorty unequal lenth headers. i have been told that even with all this, it is worthless to add a better cam without changing the stock e7te heads. Do you know if its possible to get closer to 300 hp with the stock non ported heads? Im not looking to race, I just want a little more go. 0 answer
      So, I'm trying to decide and looking for recommendations for a cam. My engine is a 5.0L HO out of a '95 Mustang GT. It's being swapped into a 55 F100. GT40p heads, 600cfm Holley carb and AOD Trans. Would the XE 266HR, XE274HR or E303 be a better choice. Not racing the truck, Just a driveable street cruiser with a little power. Your thoughts and comments are very much appreciaed. Thanks in advance. 0 answer
