Location: Kansas City, KS | Marc - I think your links are for later model engines with the cup style freeze plugs and not the disc style like Denis needs.
I already posted in the other thread before I saw this one but here's the info again
Napa lists freeze plugs for the 1961-1962 361 cylinder heads
Sealed Power - SEP 3811012
O.D. (Inches) : 1.375"
O.D. (Metric) : 34.925 mm |

Location: Northen Virginia | While doing some research in the old forums I found out that there are different posts with different sizes. Because going to Argentina with the wrong parts is not an option, I had to take the measurements myself, I also checked how Mother Mopar installed the plugs, since my car has some of the originals freeze plugs too..
the sizes are:
1-5/8 for the block 1-3/8 for the heads
My measurement technique was not the best, but with the heads installed there is no room for anything else. The measurement is taken by narrowing in on the approximated standard sizes of the plugs. As the saying goes...a picture is worth a 1000 words. As a side note, the crawl under the car was not for free, it is going to take a good amount of rubbing take all the grease and oil from my hair, arms and face but what useful info!

Location: Ramona, CA | Does anyone know what year Chrysler changed to the cup plugs? Had one fall out of my 300F and when looking for them, everyone shows cup plugs. I'm working with Melling so far to get their application listings corrected but they need to know the year span.
I know '59 is the first year for the 413 but is it the same for earlier 350 and 361 engines? |
