Product Description
Crane Cams 274 H06 Camshaft and Lifter Kit for Chevrolet V8 Engine is economically priced. They are designed with single pattern profiles and tighter lobe separation to produce additional torque and throttle response for non-computer street vehicles. This series provides broad coverage for several different engine selections. It provides a wide RPM power range for any street enthusiast. There are Energizer cams suitable for the low RPM, high torque needs of a towing vehicle. While others are more suitable for daily drive with an eye on economy, and more radical camshaft selections, right up to a weekend warrior with a street and strip machine. Some selections would even work great for oval track racing. These popular Energizer cams are made available in either a "cam and lifter kit" or as "cam only". Both are priced to be the best buy in a true performance camshaft. The rough idle option: certain Energizer grinds incorporate very tight lobe separation angles of 106–108 degrees. This feature has two purposes. The first, to concentrate the torque range and maximize bottom end power. Secondly, to produce rough engine idle characteristics. This feature brings the power band on early and builds quickly to help launch a drag car off the starting line or to get an oval track car out of the turn. It will also light up the tires at the drive-in. The tighter lobe separation changes the valve timing events, increasing the overlap period, producing a rougher engine idle.

Rump-Rump Cam!!!
By G. WILLIAMS
If you want a nice potato-potato-potato idle in your small block Chevy and still have a very streetable cam, this 274H06 will do it. Has a short 218-218 @.050 duration but ground on a 106 LSA. It will work fine in a 8.5 c.r. 350 crate motor. My use is in a 260 hp GM crate motor in a 81 Corvette with a 4 speed and 3.73 gears. Has a nice lopey idle at 900 rpm's and has lots of low and mid range power. People I have talked have used in 327's also and with automatics and 3.08 rear ends and they like it very much. You get the big cam sound without the low speed blues that you get with other bigger duration camshafts.

By Bruiser2011
This is a great cam that will not only give you that rumpity rump idle you crave but great performance as well. I installed it into my 69 camaro 350 with low compression crate motor heads and it is amazing. It pulls hard from 1800 rpm to redline and works fine with 3.08 gears although it is a 4 speed car. Works ok with stock springs too. Thumbs up from me!
