1641 With Engle High Lift Cam

There are a number of measurements you have to check out when building an aircooled engine. You must measure the diameter of the crank on the main journals and the big ends, you must measure the outside diameter for the main bearings to sit in the casing and you must also measure the rear main journal for enfloat. This is a linebored casing from VW, the diameter of the crank has been taken out 0.05mm, they have also done the cam outside diameter, which is now causing a problem as the bearings are (or appear to be) no longer available. Heritage list the bearings and have arrived after being on backorder forever, now they have arrived, it's the internal diameter that is oversize, not the outer. So this casing might make somebody a nice BBQ!
