Product Details

The COMP Cams Big Mutha' Thumpr camshaft is designed to deliver maximum performance and that signature aggressive lop idle in Ford 429 and 460 cubic inch big block engines. This hydraulic flat tappet camshaft features 242 degrees of intake duration and 257 degrees of exhaust duration, creating a radical sound while maintaining excellent street manners and drivability.

Key Features:

  • Hydraulic flat tappet design for reliable valve train operation
  • 242°/257° advertised duration provides aggressive idle and strong mid-range power
  • Optimized lobe profiles deliver the distinctive Thumpr exhaust note
  • Engineered specifically for Ford 429 and 460 big block V8 engines
  • Excellent choice for street rods, muscle cars, and weekend cruisers
  • Works with stock or aftermarket cylinder heads and intake manifolds

The Big Mutha' Thumpr series takes the popular Thumpr concept to the next level, offering more duration and lift for enthusiasts seeking maximum attitude. This camshaft delivers strong torque characteristics while producing that unmistakable muscle car sound that turns heads at every stoplight. Ideal for street performance applications where sound and style are just as important as power.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

EXCELENT PRICE,FAST SHIPING!!! VERY SATISFIED THANKS ROD.<br>

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.

easy to order and fast response on shipping.
