If I am not planning on racing my car for anything other than for "friday night" street racing at the track.
https://www.spokanecountyraceway.com/friday-night . Would I need to have the metal line 12 inch limitation. I do not plan to do any other racing. This is in a 73 scamp with a 512 ci BB. I plan to have a tanks inc. tank and pump. What line size for 500+ hp? 600hp with nitrous?
