As far as I know they have a different tire rule and the motor claim is different. I don't know what UMP does they may not have a claim. The cars for the most part are the same.

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.

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.
