OK SlantSixDan you talked me into it! I'm getting set up to do the HEI conversion on my sons '64 Valiant. I'm ordering next week Bubba's "COOL" Ignition Module cover ( Mainly because my 20 year old son like's the look of it, His money I mostly prefer function over looks ), CH410X BlueStreak cap, MO-3000 long tip rotor and Magnecor wires. two things I need are: which NGK plugs to use, motor is a'75 model, and which distributor (electronic) do I order with a good advance built in and where to order the distridutor. I had seen a recomendation on a new distributor with part number but can't seem to find it. . Oh one more thing.. recomendations on a coil to use, son wants an MSD Blaster.

Ok I managed to find the post with the part # for the distributor......There's a new one (and it's a 3874714, which has a good advance curve). AHHH that old post had a link to ebay, item not availible anymore! Well is that the right part #(3874714) for the distributor? Where would be a good place to order a new one, I really don't wan't a rebuilt one. NGK ZFR5N for spark plug tube heads but mine is the new style head, which NGK plugs??

Get a new distributor, P/N '714 or '082, from Old Car Parts Northwest . NGK spark plug UR5 for the '75+ peanut-plug head, gap to 0.040".

Thanks Dan, thats the info I was missing. Which distributor is better, or does it matter? On the plug gaps, I've seen everyone opening theirs up to .045 would it matter if I did the same or would I be able to tell the difference?

The bigger the gap, the greater the stress (and faster the wear) on the entire secondary side of the ignition. If you can live with more frequent cap and rotor replacement, and you're using good quality plug wires and a good coil, 0.045" will work.

As for which distributor to pick...I don't have a curve map of the '082 unit. I think (but am not certain) that the difference between '714 and '082 is manual vs. automatic trans, respectively.

Ok that makes sense, guess I'll stick with .040 for now. Our tranny is a manual so i'll order the 714. Thanks Dan.
