The interesting distributor info just keeps piling up....some gems;
1. if you can disassemble a dizzy down to just the body and shaft, you can install the complete insides of a duraspark dizzy (though as previously mentioned rotor phasing should be checked)....this is good because;
2. some late model 5.0's have smaller dizzy shafts than early 302's!!!
3. 351 clevelands, modifieds, and 400's have the same exact dizzy as a 429 or a 460, and FE motors can use a duraspark dizzy from a mid 70's 360 truck.
4. 351 Windsors are on their own unless you just swap the duraspark guts into a 351W point dizzy.
Now here's an interesting one.....I'm in the process of gathering parts to build a healthy street Cleveland....and just acquired a 460 duraspark dizzy.....while looking at a 69 302 I noticed
THE BODIES OF 335/385 SERIES AND SMALL BLOCK DIZZY'S ARE THE SAME, ONLY THE DRIVE GEAR IS DIFFERENT!!
I'd be ticked if I didn't get that 460 dizzy for 25 bucks off egay /forums/images/icons/smile.gif
P.S. If you have a vacuum advance can that isn't vintage, and can't realistically be disassembled to adjust, use a mirror and a flashlight and look down the vacuum connection hole.....if the periphery of the hole is hexagonal down inside a bit, it probably can be adjusted with a hex wrench!!!! (clockwise speeds up vacuum advance, counter-clockwise slows it down!!)
