The problem with 350 carbs and restrictor plates is every one has to buy a light weight crank and rod piston assembly.. there for cost rise. I parked my imca car 2 years ago reason was what you stated to much cost on rear syspension. shit I still had leafs. At 63 years old I am racing a super stock camero. this year 3rd in points won one and ran second 7 times.. I will not soak a tire. I think the cemicals cause cancer so the guy who soaks them will out run me. But I will still be alive and he will be dead. We have had 7 owners crew who soaked tires die with in the last 3 years. Shitty tires are about the only equal iser. maybe non adjustable or buildable shocks. I hate claim rule as its a rich mans game that way. I have a friend who the week after geting claimed would wreck whoever claimed him. Vintage racing has also gotton out of hand . Several of the Georgia guys are running late model chassis with18 degree engines. I will shut up now.. Bobby..
