427 street and strip tuning info from the 60's?
« on: March 02, 2016, 09:57:02 PM »
I have a nice collection of car mags from the 60's which have good tuning info on other makes of  cars and engine setups but not much on info on setting up the 427/425 combo for street or class racing.
Any of you have vintage info on what was done on the tune of these cars  for performance when they left the factory?
I do have one book but it is on the Tri Power 390 and 406 but not the '64-66 427 cars.

I picked-up my '64 Custom during the first part of Feb of '64. As soon as the weather got warm enough to work on the car, I made sure that the diz was in the ten degree slot and ran the initial up to 18 degrees. I installed a pair of 'dump' pipes direct off the manifolds and played around with the jetting, although I don't remember what I ended up using. I made my own deep pan and used the factory 4.11. And I used a set of M&H 8" Dragsters on the rear. I put spring jacks in the front coils and had the suspension dialed-in. And used a set of Traction-Masters out back. In that configuration I did a best of 13.27 at 107 after driving out to Milan.

It was my daily driver and I took it to Sebring FL for the 12 Hour race. On the trip I got a best of 16 MPG and averaged 11.7 for the trip, driving over 100 MPH as much as possible. I used a 3.50 for highway driving. 3rd gear was good to about 125 MPH which made for an excellent passing gear.
