I see no one commented either positively or negatively on my reduce the weight comment.
While lots of folks are concerned about power, one can easily pull a quarter of a second off a quarter mile time, and with some careful planning and purchases, more than 1/2 second while EVERYTHING else is left alone.
Easy reductions:
Aluminum wheels
Aluminum intake manifold
Less easy reductions:
Aluminum transmission case
Aluminum rear drums (in some cases)
Distributor housing (both CI and AL used)
Water pump housings same as above
And you can go overboard if you have a mind to do so (an AFB weighs less than a Q-Jet or Holley, and a TQ weighs even less).
Not going through everything, but I took almost 500 pounds off of a 1974 GTO. That is 8.6 percent of the shipping weight for the car.
