Re: [AMC-List] rambler hot rod // backwards six

[Tom Jennings <tomj@xxxxxxx>]

Well I didn't expect so many ideas from my hare-brained project
thunking... but I think when all is said and done, that if I
do decide to make a rod it will be conventional front engine,
rear drive, for the simple reason it is a no-brainer to assemble
with standard parts, and I can keep it all AMC, and that I have
a lot of the hard parts right now in my pile.

I guess I've decided that I want to build the Navarro test mule
motor into a hot rod; that I can make a Z exhaust pipe to get it
literally out of my face; that more usual hot rod chassis stuff
will be OK (I might afford to actually build and complete it).

I don't think the Navarro Rambler parts I have amounts to
anything historically preservable as-is; it's not a complete
motor, it's a pile of different motor parts, so building a hot
rod motor from it seems fine to me.



But with all the cogitations it appears that building a
reverse-rotation AMC six is pretty straightforward -- pending
directional oil seal issues etc I think it was Nick pointed out.

to wit:

* Replace timing chain with gear drive --  cam goes backwards.
* put chevy 6 gear on distrib -- now distributor forwards.
  (but cam helical *lifts* distrib gear, not pulls it down
  into the block) oil pump runs right direction. (note1)
* serpentine water pump with V belt or vice-versa, water
  goes right direction.
* rewire starter for bass-ackwards rotation

note1: that's with a stock cam! 

In stock form, the distributor shaft is pulled down via tooth
face friction onto the thrust washer in the distributor;
with stock cam run backwards/chevy dist gear, it would lift;
shimming the shaft to limit lift under the dist gear should
fix that, and oil would still walk up the shaft normally.

If the distributor gear direction does matter, then a custom
cam with "chevy" gear cut on it, and stock AMC distrib gear,
will accomplish the same thing.
