DAMAGE CAUSED TO ENGINE. RUNS OK BUT A NOISE IS HEARD.
1961 Chevrolet Truck

*(1954 Truck year)Throttle return spring fell off carb on freeway. Stuck at 6,000 rpm's for under a minute. Pulled off freeway dropped into neutral and shutoff engine. Backfire heard. Temp might of been at 240. Took 10 mins to restart to drive the 2 miles home.
Starts ok noise heard. Engine sounds ok but there is a scrapping sound. Only ran to try to pinpoint problem.
This is a pre '86 SB350. Mounted in my '54 Chevy 1 ton Flatbed. Very low mileage on a Crate motor installed 5-6 yrs ago.
I run NPG+ coolant, no water. Oil level is maybe a qt low right now.
Trying to determine what the damage might be to avoid taking the whole motor out with no funds to repair at this moment.
