You can run aluminum heads in UMP, and they use hoosier tires instead of mccrearies.

I think every sanctioning body should allow spoilers!!! I'm looking forward to putting a spoiler on next year for the new TORA modifieds.

you can run more aluminum parts in ump also that are not legal in imca.

The difference in chassis is none, however, in UMP, the motor claim is $750 plus exchange, you can run aluminum heads, and a bert/brinn style tranny. The tire for UMP is different in different parts of the country. Some places mandate a Hoosier D-40 and others mandate a Hoosier A-40. If you have an imca car and are looking at running a UMP track, these are some things you'll have to contend with.
The IMCA rules say that the motor claim is $500 (I think) with NO exchange. For this reason, claims are more prevalent in IMCA. You must run steel heads, and a stock type tranny. The tire for all IMCA tracks is the IMCA McCreary.
Hope this helps to clear this up, and ...............See ya at the track!!

You must run a Hoosier D-40, A-40 or H-40. You can do minimal sipping on the A-40. No exceptions.
