ok two things are becoming clear to me, from this thread.
1) Swapping heads from another engine family onto the AMC block isn't likely to happen. This motor has no cousin but the 2.4L
2) However...the design of AMC block
will allow for a totally redesigned cylinder head, regardless of the distributor or pushrod bores. The problem is cost, but the engineering is possible. I
This 6.2 diesel is crossflow, four valve per cylinder, using angled rocker bridges to "twin" the valves. The rockers are unequal reach, driven by an odd cam. The familiar straight row of pushrods is on one plane, driving a shaft mounted rockers.
On the cross flow AMC head, the intake manfold could be located on the passenger side, with runners bent around the distibutor. The spark plugs could relocated to the exhaust side. But this would be major bucks to design, and mill. Not happening. No wonder hesco crumpled this idea up. Where's the market for the head, manifold, and exhaust system redesigns?
