Just a bit of information. Direct Connection sells a pcv system that is identical to the originals, with the cap and everything, look in their restoration parts. I used a 1960 carb with the pcv connection on it just adding the correct length of 3/8 fuel line or pcv line.. or you could use your original carb with a base plate spacer you add a 3/8 nipple too. This sure is alot better than breathing road draft fumes. Chrysler used a Douglas Donaldson valve as early as 1951 on the hemi engine. they were fastened into where the draft tube normally was fastened on the valley plate filler. I have been told this also helps the engine to have less cylinder wear. Hope this will help
RickyMopar, Can you supply the part number for us. I don’t have a Direct Connection catalog in my stash of Car manuals. I do have a Year One and a Paddock catalog maybe it is in there.
Thanks for you help!
