Hey sidedog, don't give up, you can figure out a way to run if you really want. 

As far as me, I am in the early stages of building a super stock. 

There is no physical way to get an older chassis to weigh low enough and get the left side percentages to be correct without buying a new chassis,  so you save money on a motor to spend even more on a chassis
2625 with 60% left side weight for a 602 crate

Easy fix would be to get rid of the 602 engine option in LM.  Seems odd to me that 602 powered LLM's seem to be winning the Pro LM races.  Or if you want to keep the 602 raise the min. weight of all cars.  There is no way cars should be built to race at 2625, at what weight does safety start to become a concern.  The lowering of weight rules in LLM and LM over the last several years has done nothing but obsolete many good older chassis'.  Driving up costs with new light weight chassis, latest light weight bolt on parts, all of which seem to break/bend very easy.  Sure maybe the lap times are a bit quicker but does that make the show better.  I would rather watch 25 to 30 half a second a lap slower cars than 12 to 18 slightly faster cars.

Ya a more affordable power plant, but in order to get the weight low enough you are buying a brand new $50,000 mccoll pro/limited late that weighs 2625lbs. What's cheaper a $12000 Asa motor that you already have with your current chassis, or a brand new straight rail late model with a $3500 602 crate motor?

Ummm, ???? 604  in your current chassis ????

With all the lm guys leaving they can get a nascar guy to run a Chaos car next year LOL
