i feel your pain .. before i built my V6 pinto i had fashioned myself a heater box out of plywood and ran some hoses to it so i could have heat in my other pinto to drive it in cold weather .. my thinking in going fast is to make it light .. non of my toys has anything left on them that has nuthing to do with going fast in a hurry .. my V6 car aint no speed demon but it fills the need now and then
