The problem with running the Mag on the street in my GMC wasn't the mag....it was the fact that the rods and pistons are just too darn heavy

The BMW is a little hemi.....loved lottsa advance.....if you didn't start the fire early it would never get over the piston lump

The old Sentilla/Vertex and clones are about two amps newer mags will make many times that.....A friend of mine went to twist a new mag and ended up on the ground foamin' at the mouth. If he'd had a pacemaker he be dead!

Street or racing? I guess it's all in what you call street.
I've build street motors for guys that used warm up plugs and half way to work switch to cold ones.That was their STREET engine

Anyone that wants to put a 12 port GMC on the street may be talking different kindda streets

My is just gonna be a mild 400hp in a Sam Barris chopped 40 Ford coupe.Most people wouldn't wanna drive the car with any engine cause you can't see outta the 3 inch rear windows
