GT class configuration...

[Dwight Southerland]

To calculate GT combinations:

1) Go to www.classracerinfo.com
2) Register as a member if you have not done it already
3) Go to link for Technical Tools
4) Select NHRA Classification Tool

5) Select your car year-model (1971 Plymouth, 1987 Camaro, etc) from the drop down boxes

6) Click on the specific make-model-engine combination from the classification page (looks like an NHRA class guide page)

7) You will see Stock-Super Stock classfication information. At the bottom of that classification information page is a button titled "GT Classes". Click on it.

8) Select the engine you want to use from the list that is displayed and click on the button "Classify"

9) Ta-dah! All the GT classifications with weights, classes and indexes for each eligible classes.

Dwight, you've been commended on other threads for this great tool and in my futile attempt to find a traditional SS car within my budget I have started to get more serious about making it a GT class car in order to use some of my inventory. The tool you created is absolutely phenomenal in terms of time savings for the racer looking to find a good competitive GT combo. Thanks!!!

[Dwight Southerland]

Gee thanks, Jim! I'm humbled by the complement.

Does anyone see a button for GT Classes? I don't. I have emailed Dwight.

Dwight this is a great tool and maybe I'm missing something but what if you have a replacement head and NHRA has added hp how do you look that up?

Just about every engine that I could use in my 1967 Fairlane or 1969 Mustang with aftermarket heads has hp added. I know how to look it up on NHRA's site and today was the first time I looked at your site and was surprised that it was only listed with stock heads. It is a lot easier getting aftermarket heads when building these classic cars. I want to say again that you have done a great job putting this all together.
