I believe Energy Suspension produces a polyurethane kit, I think that's where I got mine year ago.....
Sent the engine for a rebuild. Stock short block rebuild with KB pistons, AFR 165 aluminum heads, Comp Cams XE268H Cam, roller tip rockers, Edelbrock alum intake, Edelbrock 600 carb.
Your Kings looking great, I assume that custom length pushrods were needed with that combination?
Wait...
Did these thing come with dumps?
I ask because I don't know.
No. Mechanically they were basically identical to any other V8 equipped II. But mufflers tuck under the rear seats nicely.
