Well im not a DHRA official thats for sure but i can kinda tell whats hot and whats not, but like i said im no expert. As far as trucks it kinda varies, alot of showboaters with 500hp trucks with there bully dogs and such if you know what i mean. I was thinkin maybe stock, super stock, modified and open, but i guess there is a lot of variables in those classes, as to what can be run and not in each. Maybe stock, mod and open would work since its really our first run at it. Im pretty sure ill have a lot to say in who goes where i just want it to be fair is all. DD
