Re: Access to AMA Shipping Weights?
The N.H.R.A. Technical Dept.gets a big fail for not sending a notification to all the racers or at the very least posting a statement on the Competition page.
I was impressed with Lonnie, but this is just unacceptable. Last edited by Frank Castros; 02-06-2022 at 06:12 PM. |

Re: Access to AMA Shipping Weights?
Shipping weight can be adjusted by NHRA at a whim. A few years ago they changed the shipping weight of 89 Mustang coupe to a lighter shipping weight to make that body group for 1987-1993 unable to change 4 classes as the weights between those various years and models were originally listed from the factory. Some years were light and most of the 89's were heavy depending on transmission and model. A couple of us got bounced out of N/SA when they made up a new weight for the 89 coupe.

Re: Access to AMA Shipping Weights?
I was surprised to hear how often racers take on the task of correcting shipping weights. I know someone who reached out to NHRA to correct the shipping weight on some Fox bodies, and someone else who was correcting them on certain Mavericks and Comets. I wondered how the info that they dug up was different from what NHRA had and put in the guide years ago.

Re: Access to AMA Shipping Weights?
Like I said a lot of interesting information in the AMA sheets: a 68 FE 390 valves are ground on 45* for all Hp listed. The 427FE valves are listed as being ground on 30 *. Both the engines with 4V listed as .4809 lift intake, .490 exhaust, with hyd lifters.
Ford had a daisy chain on the engine adds, from a 302 2V up to 427 4V. This is the chain on a 1968 GT Torino Fastback your choice of starting weight. Curb weight. 3362# About 95% of curb weight Shipping weight 3208#. 390 2V vs 302 2V +243# 390 4V vs 390 2V. + 37# 427 4V vs 390 4V. + 70# A similar process is used on the transmissions |
