The last picture with the twin triangular air cleaners with the foam element....that catches fire on back fires.... flame throwers....
The other pictures, only the M1 TR is mine.
On your opinion given on a single plane on a stroker, what ever..... your best bet is to talk to the people that race them. Your vast knowledge is best suited there with them.
I was just reporting what others have reported.
I myself would run the single plane. 99% of the racers here are not heads up racers but bracket racers. My wallet is to thin for heads up. Since bracket racing is just being consistent, one could run a totally screwed up combination and be a winner if they are consistent.
