Product Description
These cams are new billet cams and are NOT regrinds or welded (They have full base circle).
256°: Stock camshaft grind for 325i. BMW Reference #11311716138
272°: A great upgrade for a street hot-rod E30 325i with M20 engine. The design and results are identical to the Schrick 272°; the higher lift helps mid-range power and the extra duration helps the top end. This cam will pull right up to 7000 rpm, and works well with upgrades like chips, free flow air filters, headers, etc.
284°/280°: This is our house-brand 284° intake and 280° exhaust dual-pattern camshaft. This cam is especially well suited for an aggressive-street/dual-use M20 engine build (ideally a 2.8L, 2.9L, or 3.0L stroker). It will make plenty of mid to high range power. This camshaft is not smog legal.
**292°: Slightly milder than the 304° cam we offer, this is still a cam to be used in mostly race application. Improves mid to high range power. This cam is not smog legal.
**304°: It is a very aggressive cam and meant for race-use only. It has 304° of duration and 11.8mm of lift. It will make plenty of power up high and responds well to high-compression stroker bottom ends and programmable engine-management systems. These are not smog legal, and are not a good choice for street cars.

WARRANTY INFORMATION: With new camshafts we recommend new HD rocker arms and oil containing at least 2000ppm of ZDDP per quart. Without new rockers or proper oil there is no warranty on the camshaft. (To order zddp as an oil additive, visit hskrennsport.com or your favorite oil supplier.)
**HIGH LIFT CAM INFORMATION: On our 292° and 304° cams it may be necessary to use oversized eccentrics as well as lash caps to be able to adjust the valves within spec. Please consider these items if you would like to purchase one of these durations.
