I noticed that Bill Miles GMC motor has(Hi Bill) the oil filter on the passenger side attached to the block. The Chevies are on the driver's side and clamp to the manifold.
1.a. Can a clamp on style be utilized on a GMC?
b. can a clamp style be bolted to the block
without the clamps a la Bill's?

2. If so, was that style used originally in GMC?

3. where do the lines hook up?

228 GMC motor.
