Size of freeze (core) plugs in head?

[nmon]

Hey guys,
I've been looking around and haven't found an answer yet. Would you happen to know the size of the freeze plugs that are on the heads? The car is a 69 runner with a 383. Even a Dorman part # would help. Any help is much appreciated.




since I'm new, here's a pic of her. Just got her

hi, which core plugs? on the head ends or between exhaust ports? different size plugs...... :drive:

Ya I just found out today. Got my hands dirty. 1" for the ends and 1 1/4 for the exhaust side. Stubborn little buggers

Thanks for the warm welcome. Well I got all the freeze plugs in the head changed and then found out the block plugs were rotted out. When I was under the car it looked like there were only one on each side. Is that correct?

Pretty sure she was someones weekend warrior before. She had old school traction bars (Mr. Gasket brand) and the freeze plugs were all rotted because it looked like there was never any antifreeze ran in the car. That and the body was in great condition. Numbers matching 383 with only 62k on the odometer. Sat in a garage for a long time. All the interior is there and in original condition. She was quite a find.

should be three on each side of the block. They can be changed in the car, even with headers, but a PIA. My first '69 had sat for 10 years, and the block plugs were rotted. The ones behind the motor mounts are ESPECIALLY fun......
