Re: [Chrysler300] 413 Welch plugs



Thanks, John, for your input. 

I installed the plugs several years ago. They are holding up. My '64 Newport was a project car, to be sure my 300E would get the best equipment and parts. I am not going for points. But, I am a believer in doing what is right in my restorations. Can you send me a source where I can get the correct plugs?

Best,
Ron Kurtz

 I think to do this right you have
 to machine the block to remove the lip the flat stock discs
 sit on . Just putting GM style cups in the holes does not
 work correctly . They need to go in flush all the way .
 Maybe you did this machining? If not they will not grab as
 designed .precision size of hole too ? 
 I am
 a big believer in the hot heads aluminum plugs held with a
 stainless steel bolt and toggle bolt like strap . This
 cannot come out . The bolts from hot heads are slightly too
 short aggravating putting them in , unbelievably so , inside
 parts can drop into water jacket . You are done for . I had
 a bare block got the toggle bar out of top of block. Get 1/4
 longer bolts . Made for 392 , may be same size as B , and a
 bolt in . The o ring  sits on the block lip. Which must be
 clean .  lost a disc one on first trip on 392 ,huge hassle
 you get 2 minutes to boiling in head.  very tricky to get
 in right with stock , but stock works. A skill issue . No
 one does this in 2017, they do not have the experience . But
 stock rusts too . On heads maybe cups are a good answer ?
 Machining them anyway at a rebuild. 
 Bottom
 line hot heads bolt in plugs end this problem on block. 
 And can be done without machining . Need to check if 413?and
 392 same size . A good machinist can make this too . John G
