Frank: As you know, I proudly have AMC,s the 79 Concord Electric, 79 Pacer Wagon DL 304 w/Leather, of course the 71 Matador, that even up here have asked me to show, but concern about driving it, the car is everything that Skip said, I have had many stop and look at it, of course I have my 83 CJ 8, barn find, 350 miles on it. Scored a 83 Eagle wagon with 70k, Still have 3-343 complete, looking for right body for them, one is dynoed @408H.P. I AM LOOKING FOR HELP FOR MY FATHER-IN-LAW, WHO WAS A MEDICAL MISSIONARY IN INDIA FOR 30 YEARS, CALIF SENIOR TRAP CHAMPION, BUT SUFFERED A MASSIVE HEART ATTACK A FEW DAYS AGO WHILE SHOOTING, 75+, A FATHER-IN LAW MOST WOULD WANT. My wife who is in M.D. area, is flying out to help transport him to L.A. from Clovis C.A..,,yes I know, but they are frigule, lived there lives sparingley, penny wise, can not change them,wife also that way growing up in India, living in a 3rd world . I would ask any member of the AMC group for helping my wife mount a roof rack on there Sentra so they have room in the car to transport him. If there is a member in the area, I need to contact them for help to mount a carrier. CNN today reported only 31% of youth polled know what the 4th is about,,I loved being a teacher, but what the hell is going on!!

One gear is driven and the other "floats" on a shaft... with the exception of the "pancake" type, they have a small driven gear running inside a large floating driven gear... so in that respect they are similar too. > > The angle of the pump makes no difference -- the 232/4.0L pump gears are VERTICAL and run against the cover more than the 196 gears do. Most V-8 oil pump gears are vertical also. The AMC V-8 oil pump goes out the bottom at the same angle as the distributor -- much steeper angle than the 196 but not vertical like the modern AMC six. All the Nash engineers did was consider how much clearance they could/wanted to machine to then made the gears long enough to deliver enough volume at those clearances. The gears on the 196 oil pump are a bit longer than those on the more modern six, but tolerances are a bit closer on the newer one too. At most the material the gears are made out of may be different and expand more, but in a nutshell you just "improved" the pump too much! Loosen it back up with a thicker gasket. You'll know immediately if that works by the oil pressure gauge. > > ------------------------- > On Fri, Jul 2, 2010 at 5:26 PM,<wrambler242@xxxxxxxxxxx> wrote: > > I'd guess that the cover being steel compared to cast means next to nothing. > > ? ?Probably 90% plus of modern engines have cast body w/steel covers. > > Tom replied: > > Yeah, but not Nash's design!
