Just looking for advice from people with more experience than myself...I grew up around racing and I'm a mechanic (in training). I have mechanical experience but I lack in racing experience. (Shocking to believe, they are not the same thing.)I have a '71 Chevelle that I can't decide what combination (engine, trans, gears, etc) I want to use. I race local tracks (mainly a quarter mile asphalt low bank track).. Any suggestions on set-up and/or engine options? Not looking to cut corners but I want the most bang for my buck like anyone else.Considering a 406.. Lower RPM but higher torque.. 509 casting. Higher Nickle content. No substitute for cubic inches..Biggest thing is I don't want to do what everyone else does. My track is pretty open in terms of rules. Single carb, 23* cast heads, wet sump..Thoughts, advice or suggestions?
