4 Piston Racing USAC Midget CAMSHAFTS (K-Series)

Availability: In stock

4P-RRmidget-cam
$1,300.00

Quick Overview

This camshaft was specifically designed for our USAC midget engine program, and is now available for purchase outside of our engines. This is NOT a big drag race cam. It provides plenty of low end punch to pull the car off the corners, but will allow you to run your engine up to 9800+ RPM down the stretch. It is designed for smooth valve operation that is easy on the cam chain, guides, and tensioner. Pair this with our 4P Midget Cylinder Head and 4P Adjustable Cam Gears for a complete package that can produce 380+hp at 153 cubic inches. Camshaft can also be used in 145 cubic inch engines, with great results.

Intake Lift - 0.533"
Intake Duration - 260 @ 0.050"
Exhaust Lift - 0.513"
Exhaust Duration - 260 @ 0.050"
