Drag rubber was the hot ticket back in the day for a few reasons. As you said size was one thing, compound was another. Drag slicks were made softer to provide traction on take-off, so with some grooving, they worked well for dirt racing.       As for engine combinations, in the old days, a modified was a modified because it was a big block. If it didnt have a big block it was a sportsman or modified sportsman ect. like you stated with Flemington's divisions. Some tracks found their niche with the old sportsman modifieds as a headliner, such as Big D and Grandview rather than the full blown mods such as Reading or Flemington.       With the advent of the modern sportsman division as we know it, the old sportsman modifieds were reclassified as 320, then 358 and/or small block modifieds.        Modern sportsman developed as basically a 358 with more limitations, but became almost as expensive as a 358 modified engine. A simple 2 barrel to 4 barrel carb change and the were basically the same. The crate engine is a more stock version that is supposed to be less costly.        Big small blocks, in terms of the modified division is usually around 430 c.u. These can be very pricey with all the maching required.       Different engine combos work better in different cases, depending on size of the track, slick or heavy surface, flat or banked, even shape of the track in some cases.
