Well, the 67 stang is in the shop having some steering work and suspension stuff done. While it is there I am going to have them check the rear end out (find out what gears it has exacly) and just have everything "checked over" (compression, vacuum, etc.) (yes i could do this myself but while it is there might as well have them check it)
Also having the heads checked ( i think it is burning oil) hopefully everything comes out OK.

Now for an interesting part.. I dont know what the gear ratio is (PO said 'they were low') it launches pretty good, so lets here some guesses as to what you think they might be (when i get it back i will post what it has)
my guess is 3.80's
my dad thinks they are 4.11's
lets here what you think!
also what are some good aftermarket heads, for a 'fair' price?

 

If your car has the data plate, look and see what the axle code is. If the rear end is original it could have 2.80 to 4.11

 

is the data plate the tag on the door?
if it is it is gone (the door is of of a wrecked 68 (PO didnt change the door tag)
but they aren't original anyway, the previous owner said his PO changed them..
