Web Cam Type 4 Camshaft, 251 Grind, 00-292 is designed for Type 4 engines, and requires Type 1 Lifters! It's specs are .546" Valve Lift with stock 1.3:1 Rockers, 324 degrees of advertised duration, and 285 degrees of duration at .050". Awesome Powerband from 4000 to 7500 RPMs, the more headwork and carburetion the better the top end will be.This cam was designed for road and oval track racing, and it has a very strong upper end. This cam has won a LOT of races, do you have the rest of the engine to match up with it? Chevy Springs and a lot of RPMs are in store for you! We feel that you need at least 11:1 compression, and now are you at the point where instead of running better with more headwork and carburetion, it will simply run like #$()*& if you don't have it!
Powerband won't even start until 4000RPMs, but when you hit 4k HANG ON!
This cam works best with a 11:1+ compression, and the more headwork and carburetion the better it will run.
Web Cam camshafts are what we consider a "High End" camshaft, they are fantastic! You can have the exact cam you want, you select the Lobe Center and Clearancing, but these camshafts cost a lot (they are worth it). Web Cam always is State Of The Art in their grinds, they aren't using grinds from 30 years ago, ALWAYS the latest technology! If you don't have the budget for a Web Cam grind, you will probably be happy with a SCAT Type 4 Grind.
Stock Lobe Center is 108 degrees, if you are not sure which one to get, 108 is a good choice. Tighter Lobe Centers (100-105) will generally increase low end at the expense of top end by increasing valve overlap. Wider Lobe Centers are often used for turbocharged applications. We offer a range of Lobe Center options for guys that have researched the topic thoroughly, and want to order a cam with a specialty configuration.
The Stroker Option provides more lobe to crank/rod clearance, it's a good idea if you are building an engine with a 78mm stroke crank or larger.
