|VW Engle W120 Camshaft is a Hot Street VW Beetle and VW Bus camshaft grind is designed for 1.1 or 1.25 rockers, and it’s specs are .397″ Cam Lift, .435″ Valve Lift (1.1 Rockers), 294 degrees of advertised duration, and 253 degrees of duration at .050″, on a 108 Lobe Center. WIth more duration and slightly more lift than it’s little brother the W110, this cam is designed to give more power at the top end while sacrificing low end. However, you can not use this with a stock carburettor, it will barely idle well with dual 1bbls or a centermount 2bbls. You really need at least dual 2bbls carburettor for this cam to behave at idle and under 1500 RPM.
This cam really needs some port work and/or larger displacement to work properly. Expect a power-band of 2000-6000 RPMs, the more head work and carburettion the better the low end will be. If you use 1.25 rockers, you will extend the top end to 6300 or so.
Dual springs are required with 1.1s or 1.25 rockers. Use a compression ratio of 8.75-9.5:1.
