IHRA Crate motor class/Weight

Rich67stang · 10-09-2012, 11:42 AM

I have a 1987 Mustang coupe, 302 crate motor rated @ 295 (aluminum heads), automatic. What would be the min weights for H,I,J /CM classes.

Thanks,

Rich SS/DM 161

PS Thanks Chris 1529 for help.

Your car's shipping weight is 3014 (302 auto coupe) which with a factored h.p. of 295 would make I/CM it's natural class.

Raceweight w/driver would be:

H= 2973 lbs
I = 3120 lbs
J= 3268 lbs
