Or, you can do it by the codes...

PS:
You thought about just putting some shorter rear tires on it ?

 

Like that manual you posted up. You know any for the old 50-70 Novas, Malibus or Impalas. My grandpa has a 40 car garage on his farm with all sorts of old Chevys in it and would love to buy a couple off them and start fixing them up. I wouldn't mind making one nice for racing though, wouldn't be an everyday drag style car just one for fun once a year.

 

I have 3.75 ratio and it works really softly.
Check out the clutch, possibly is not ok.

 

Haven't run across any Manuals for those yet.

I've done a lot of Quarter Mile in my years, and I wish I had the foresight your GPaw had. I'd be a rich man today, if I had preserved the originality of some of the rides I've owned, and kept them.

mc7 needs some help here, so, let's not stray off topic...ok
