OK, I can also attach a small broom to the horizontal antenna and perform a public service by sweeping the gutters at the same time and maintain a perfect ground! Now what about the question of 1/4 or 3/4 turn on the hydraulic lifters? Holy Valvecover (x8) Streets! I give you a little compliment and you give me a grounded antenna! Actually your idea would work if the tires were perfect insulators, but those with positive ground systems such as the '48 Cadillac and early MGs know that tires do conduct a little bit AND the Earth is actually NEGATIVE, not ground=0 volts. This is because negative electrons from the Sun are trapped by the Earth's magnetic field whereas positive protons are more massive and whiz on by the Earth so that overall the Earth has extra electrons and is actually negative and that means that the ground cable of an auto electrical system should go to the negative pole of the battery; otherwise you are bucking the whole Earth! That also explains a lot of difficulties with British car electrical systems that have positive ground. Now what about the 1/4 versus 3/4 turn on the SBC valves?

on the 1/4-1/2-3/4 turn bit - you apy for the dyno time, i'll supply the car and labor and post eth results here.

so, when the earth's magnetic feidl reverses, as it has many time n the past, will the earth then be - and the 'air' +? I s'pose we won't know that till then

I am suspect of the antenna idea. Each freq has a specific optimum antenna lenght for best reception. I beleive FM radio is 21". I know that my lincoln, with a rear deck mounted antenna does better for some reason than my cars with hood/fender mounts. Japanes cars useed to have them in the A pillar on the drivers side and the extended above the roof - not truly vertical so the roof would not have made a good ground plane. Sticking tthe antenna 'under' the car if a 'glas rod might be ok, metl on a steel one i would bet teh reception sux.

I have to put a CB antenna on my Wrangler..any thoughts on best placement on that one?
