Good God, the season isn't even over yet and you're going to beat this dead horse again???

Ed Carpenter · 11-10-2014, 07:18 PM

I don't think you will have a lot positive response to this. Myself it would not be cheaper per your rules. I would have to build a new engine and buy another clutch set up just for starters. Just my opinion.........

Wow! Tough crowd.

Also, no one is trying to "Convert" anyone. No one's trying to get cars to leave one class for another. The thought was to get parked cars possibly back.

Thought is that some people are sitting out racing because the costs are out of line. Maybe someone new might pick up an old modified or SS chassis and start here instead of fearing the 30K motor SS motors we now have...
