Terry and Morris,
I have a K&W on the driver side and a regular chrome Ford breather cap on the passenger side. I am not running a pcv yet, but I have considered that too. I just installed the tall manifold breather yesterday and it seems to work quite well. George Anderson recommended I install one because at the track I was throwing a little
oil (very little) out of my breather caps. I just took it out on the freeway and blew it out a little and it seems to be working as it should. I bought it from Enzo at Finish LIne.
The Dove expansion tank came from Jim Dove in Ohio (you can do a search on this site for his telephone number) and I like it great now, but a word of warning. When you buy one remove all the little allen head bolts and take the top off and seal it with some RTV silicone otherwise you will be mopping up
antifreeze. Once you get it sealed properly they look and perform great. You may have noticed I have my radiator outlet flipped 180 degrees. That is because I am running a crossflow radiator I had made be Arts Radiator Shop in New Jersey, best move I made to solve all my cooling problems.
