COMP Cams Camshaft CRB3 299Th R7 ThumperDesigned to deliver an aggressive, hard hitting exhaust note at idle, the Thumpr camshaft series from COMP Cams also delivers excellent horsepower gains and a broad torque curve. A perfect choice for muscle cars and street rods, the Thumpr series' early intake valve opening and long exhaust duration create optimum overlap for that race car idle. The Thumpr grinds all require an aftermarket torque converter and lower gear ratio to ensure the drivetrain

I was looking for this exact product but didn’t know it! We recently moved into a new home and had zero window treatments so needless to say I wanted something quick, affordable and not vinyl WalMart blinds. We are happy with our purchase and would highly recommend to others. Some complain of the adhesive not sticking- make sure to clean the window wells/walls etc prior to installing these. If the surface is free of dirt/grease there will be no issues with them staying put.
