Chris,

I don't think you can the 383 in GT since it doesn't have a rating for GT, just superstock. The 340, and 340 six pack has ratings. Also 340's from other years.

This may not help, but here is the 1970 dodge page from the classification guide. If you are able to run that motor, please let me know, it would truly open up a lot of options for other Mopar racers.

DODGE 1970

198 225 225 318 318 340 340 340 340 340 383 383 383 383 383
