Factory FE rocker shafts are known for breaking at the outboard ends as the end rocker arms are unsupported. You may want to check to see if the rocker shafts are cracked, bent or broken at the end rockers.

A few weeks ago while cruising in town I had a exhaust rocker stud break # 1 cyl. Maybe 2000 RPM at most.
Scared the doo doo out of me. Sounded and felt like the motor blew up.
Flat bed it home, pulled rocker covers, breathed a sigh of relief, slept very well that night.
1/2 hour job and back on the road the next day.
Follow previous advice and pull rocker covers. Could save you a lot of money and time.

Hope it was something minor.

Egreaves20:

Small world, I am in Stratford as well. In our town we have two great engine builders, Jim Coleman (over at Automotive Restorations) who runs an engine shop and Don Scinto on Stratford Avenue just past Jiffy Lube. Both are very seasoned veteran engine builders and machine shops.

Jim rebuilt my old 428 the winter before last. At a launch, the woodruff key in the upper timing chain gear broke and my valve train kinda got crushed and pistons heavily kissed. Close inspection showed that the shroud over the key was somewhat defective and probably should never have been used by the original builder who I shall not name.

Hopefully Cobra Automotive can get you all straightened out. At least from a diagnosis perspective. If you need engine rebuild work then Jim is a guy to consider. He was Paul Newman's engine guy and pretty much can work on anything. If you use him, contact him directly by going into Automotive Restorations and asking for him. He is usually there by 9AM.

Lastly, you should get in touch with me, I am up in the North End near Booth Park and have been running #375 for 20+ years now.

Great info. I’ll call Jim tomorrow. I’m in North End as well, near Oronoque. I drive a big loop down James Farm past Booth a lot. I haven’t even ventured to take valve covers off, so hopefully I’ll get some insight one way or another over next 2weeks.

Oh go ahead and pop the cover off. If you see a broken rocker arm, or bent pushrod, you'll sleep better that night.

I am on the corner of Main Street Putney and River Valley Road in the large white cape with the barn behind. Drop by some time you are in the neighborhood.

It's a tribute to the FE that you could even limp it home after snapping the end off your shaft.
