186-S Spec Suggestions
My HK Kingswood has the original 161 in it. Just picked up a 186 that was bored out of of a HP block.Also have a syncro gear box to go in.
When I put the 186 in I was going to add a bit to it:
It has extractors already on it.
Remove the old exhaust and put a bigger one in. Any suggestions?
I didn't want to touch any of the internals of the engine apart replacing bearings.
Does anyone have any suggestions on mild improvements for the the 186?
Also, what separated the 186 and the 186S?
