Re: [AMC-list] 195.6ohv, ARP studs and head torque

I have a nice big 4" Stewart Warner tach up top, and calculated RPM vs. MPH.
Tires are now 215/65-R15's (26"), factory was 6.00x15 or 6.50x15, the
closest to that I can figure out is 205/70-15 (26.4"), from coker.com or
somewhere.  That's 1.14% error (nothing).

I'm sure the tach is right, it matches my Fluke DVM, and 2200 rpm is more or
less prevailing traffic.

I did 90 in it, once, around 3000. Very floaty! Motor was fine and would
have kept going, I was not fine. I'm not sure what you'd do to this chassis
to instill confidence over 80, certainly an airdam that reaches the ground,
and a good steering box (mine's sloppy). Short wheelbase, too tall, squishy
springs...
