New website: "What class does this run?" - Page 3

Hi Dwight,

There appears to be an error in the data for the 70/71 340 Challenger Cuda SS replacement head classification. Instead of moving the car one class lighter it moves it two.
ie natural class SS/H lighter class SS/F. I went back in and it is doing it for all the engine combos.

thanks, Rod

So much great info, Thanks.

I went through the database and separated the A & G body Buicks from the full sized cars in 1964-1987 to make it easier to read the pages. I know this doesn't exactly match what the NHRA class guides look like, but the purpose was to make it easier for you guys to use.

Thank you Dwight! That helps a lot!

When you bring up the first page, with the foot note 2 it lists the Dart replacement head. When you go to engine specs it leaves the Dart head out. Is the Dart head ok? Thanks for all the work on the classification guide.

3/1/18 Updated Class Guide data for the medium riser Fords along with various NHRA Accepted Products data, specifically a new head for medium riser Fords, runner volume specs for SS '69 AMXs and a new piston for 421 Pontiacs.

The new HP changes from the Gators are now in the database.

3/21/2018 Once more it looks like NHRA jumped the gun on HP changes and had to correct some. The increase applied to the LT1 was reversed.

Mid Year 2018 AHFS HP ratings updated. Waiting on the racers' submissions.

SO, how did the '68 & '69 Camaro 396-325 and 396-350 engines get tagged with and increase and the '67 396-325 NOT get the same? More inconsistencies. It's like the current policy is to factor people instead of car combinations.
