Thanks Chuck and Jeff. Going by a old Motors manual that I have Chevrolet offered a 400 cu in small block in a 1970 Chevelle with a quadrajet with the highest hp rating that I have seen and I am assuming that is the engine being used by those runnuing a 400 sbc you see running in GT/C and GT/D. But yet I can't find that engine listed in NHRA's classification guide. I guess my next step would be to contact NHRA.
