I’ve got a 3.6 in my 83 SC.

I’ve owned the car for 6 years, I don’t drive it more than 2-3000 miles a year, had a valve adjustment right before I bought it...and mechanic gave it a thumbs up.

Owner prior to that did the 3.6 conversion. It’s been 10 years but at most 20,000 miles....both prior owners are Pelican guys.

The guy who did the swap sourced great parts, didn’t skimp in anything and he had the motor rebuilt by “one of the best guys around denver”...used ARP head bolts

On doing my valve adjustments, I found 2 nuts loose, and those two had broken head bolts.

I’m curious if this is a known thing with ARP (doubt it)...if it’s possible the “best” engine builder did something wrong.....or something else....

Anyone have some insight? I figure I can call ARP tech support just to see what they say, not expecting any freebies or warranty after all these years, just curious.
