Ray,
The best way to answer your question is to say that my car meets the
requirements for NHRA/IHRA stock eliminator. Class is determined by
lbs. per factored horsepower which is listed in the "Stock Car Classification
Guide". You can view this at NHRA.com. For my car the original factor
for the 360 hp is 10.10 which is E-Stock. However, several years ago
IHRA refactored the 1961 360 hp to 325hp. To recalculate the class,
use the original 10.10 factor multiplied by the original 360 hp=3636 lbs.
Divide the 3636lbs. by the refactored 325 hp=11.19. 11.19 is the
weight break for G-Stock (11.00-11.49) Using the lower number, 11.00,
multiplied by 325 hp=3575 lbs + 170 driver weight=3745 min. car weight
when I go on the scales.
To run in Stock Eliminator, car and engine combination must have been
available from the factory, and the engine/chassis must comply with the
various rules for Stock Eliminator.
I hope this answers your question.
