Wow, quite a thread. I have a chevy OHV conversion on my car and I guess we now have a baseline on the chevy setup. For the money, I am very happy and am very unafraid of the local flathead guys. I have a few races to run against some modded flathead engines and then I will get back to you. I will try to run the donut derelicts crowd as they all drive modded expensive flatheads. I do run a full weight coupe so I will try my best to run apples to apples comparisons. Neal Jern checks this board about never.
