Engine swap on AC B series

[tej 1]

Has anyone put a B&S Twin on a B series AC. Would be interested to know what problems one would run into. Tim

Crankshaft height being the same as the old cast motors and the possibility of the cylinders hitting the frame siderails,other than that no probs. that I can forsee. I know on the 700 ser AC'S the cyls. hitting the frame was a problem,the 900 AC'S however obviously have that accounted for.Am not sure if a B ser. frame is even wide enough to fit the twin oil pan/sump.,one other possible problem. dlc
