Overview

The Howards Cams 121133-08 is a solid roller, retro-fit camshaft designed for drag racing applications. It features 261 degrees of intake duration and 269 degrees of exhaust duration at 0.050 inch lift, with a valve lift of 0.680 inches for both intake and exhaust when used with factory rocker arms. The operating RPM range for this camshaft is 3,400-7,200 RPM, and it utilizes a 3-bolt camshaft gear attachment. This camshaft is specifically designed for Chevrolet 396-502 Mark IV engines from 1965 to 1996.

This camshaft requires higher stall torque converters and lower gear ratios for optimal performance, and it has a noticeable idle. It is not compatible with computer-controlled systems.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
