Mar 30, 2012 · SO from a standard DoD/non-LS7 lifter, you may need .150" shorter pushrod. The Lunati lifters are a bit heavier. @316 grams a pair VS 247 grams/pair for LS7. Lunati roller is .750" where as a LS lifter is @.690". This doesn't change the lift of the cam but will give it more "area" since the roller contacts and leaves the cam lobe sooner/later.
A Brian Tooley Racing camshaft is the ultimate compliment to your LS or LT powered vehicle. Whether you have a Silverado or Sierra pickup truck that needs a little extra towing power, a Camaro or Corvette that needs a rowdy idle and quicker elapsed times, or a simple cruiser that's used for ice cream runs and burnouts, BTR has what you need!
