35-602-8 BIG MUTHA THUMPR 243/257 Retro Fit Cam Camshaft with HP Link Bar Lifters | LIFT: .552″/.538″ | FITS: Ford SBF 289 302 351 351W Windsor | Street/Strip | Very Rough Idle

Description

If your build is all about sound, power, and presence, this is the camshaft combo that delivers it all. The 35-602-8 Big Mutha’ Thumpr Hydraulic Roller Camshaft Kit with Redline Performance Retro-Fit Lifters is designed to make your small-block Ford sound ferocious and perform even harder.

The Big Mutha Thumpr is the most aggressive grind in the Thumpr series, built for enthusiasts who want the nastiest idle and the strongest midrange torque possible. With 243° intake / 257° exhaust @ .050″, .533″/.519″ lift, and a tight 107° LSA, this cam creates incredible cylinder pressure and unmatched throttle response from 2,600 to 6,200 RPM. The result? A deep, violent lope at idle that sounds like a full race motor — and the kind of torque that makes every shift feel like a launch.

The included Redline Performance Retro-Fit Link-Bar Hydraulic Roller Lifters take the headache out of converting older 289/302/351W blocks. They’re drop-in ready — no machining, spider trays, or dogbones needed — and built for stability, precise oil control, and long-term reliability.

Built on the 351W / 5.0 H.O. firing order (1-3-7-2-6-5-4-8), this kit gives you the best of both worlds: race-proven technology and the Redline quality trusted by professional engine builders. It’s ideal for Mustangs, F-100s, Fairlanes, Broncos, and street rods running serious compression, heads, and stall converters.

This isn’t a mild performance upgrade — it’s an attitude adjustment for your entire car.

From idle to redline, you’ll hear it, feel it, and know exactly why it’s called the Big Mutha’ Thumpr.
