Close up of rhs cam showing adjustable cam gear. The drive belt is a 193 tooth 8mm pitch HTD type belt, the camshaft protrudes 2 1/4" forward of the valve cover and lines up with the water pump pullys etc, an alternative is to shorten the cams by 1 1/2" and drive the cams together and use a second belt to drive everything else, you can tell me your preference. |
