Hey guys.... I've been looking for an all in one distributor for a while now, and came across this unit from Doug Herbert Racing... it's listed on the website for $ 118.00 but if you tell them you saw it in a mustang and ford trader for 99.99 they will accept it. This unit has a built in coil on top like the GM units.... it pretty much is... so this does away with the cylindrical oil filled coil we have. It is 50,000V and best of all, it's spin rated to 6,800 rpms without misfire... and cheap too... Mine will be in tomorrow, i'll keep you posted. I just thought this was a good economical way to clean up the engine compartment, and do away with points instead of pertronix... oh... and $10 shipping... ohh... and best of all.... summit racing sells the clear Gm caps to fit this, so you can see the electricity. thanks. ~Dan.
