I know I will take a beating for this... but are 1980s Hondas with mid-2000 motor swaps still "in the spirit of the class" for SMF? There are many 'good' FWD platforms out there that have been competitive in other classes over the years, but it seems nobody is willing to push into SMF with SRT-4s, Speed 3s, Minis, etc as an 1800lbs Hondas (yeah, yeah you ballast up to 2000 now...) with a K-swap is just damn near impossible to match.
At the local level there appears to be much more diversity, but at the national level...Homogeneous Hondas rule.
Looking at SMF related posts here, there are people thinking about non-honda SMF builds.
What if you could only swap motors +/- one generation? Or +/- 5 years?
Just thinking out loud...
