I am building a outlaw ss/drag radial car. The class I want to run has a 150# penalty for alky. It also has a 75# penalty for a air to water cooler so if I run alky I don't need the intercooler so really its only a 75# penalty. I will also have less weight in tubing and water so do you all think alky would make enough power for the penalty. How much more power will alky make? If I run alky do I need a radiator? By the rules a small block with a 106 and fuel injection on alky will have to weigh 3525#. The class is a 4.90 5.00 range .Thanks for any advice.
