Re: IHRA classification guide
per the NHRA classification guide, the shipping weight of your car is 2968#.
for the 347/450, IHRA rates it at 430HP. 2968/430 = 6.90 lb/hp. which makes it a B/CM (6.5-6.99 lb/hp) your race weight for B is 6.5x430+170( for driver) = 2965# you could run A/CM or C/CM by subtracting or adding 215#. I doubt you could get it light enough to run A though. I am not sure how much IHRA rates the 340HP 302. assuming it is 340, 2968/340 = 8.72 which is F/CM (8.5-8.99) it may only be rated at 320 though. I don't have my lates drag review with me. You can see the rulebook, class indexes, etc. on IHRA.com
