I need a cheap (Buick) V-6 odd fire HEI distributor. The one in the TR-7 (with a odd fire V-6 Buick) motor I bought is dead as a hammer. I just want a cheap one as I'm going to change the motor (even fire) but I'm getting tired of pushing this pig by hand around the yard. I pay by Paypal. Thanks
I think 66-77? The only difference I noticed between evenfire and odd fire was the arrangement of the plug wire terminals on the distributor cap (top) as well as the small square slot for the distributor cap to slip into (its in a different location on the distributor base) so it doesn't rotate after being secured with the "L" fastners.
Thanks for looking. I'll wait a few days to see if someone has one cheap and if not just pull the motor and put my even fire one in it.
I don't really remember if it is an odd fire V6 or not. I though you might know by the model year. 1975... Also, I can't remember the differences in a regular even fire V6 and an odd fire V6. Refresh my memory, or better yet send me an odd fire picture to use for comparison.
First of all, the car is a '76, not a '75. I looked on the fan shroud cover to find out for sure. Is this the distributor???????
The clearest explanation I've found on how to identify the difference is at beforeblack.net/NAnotes.htm (pardon the non-URLization of that but my post count isn't yet high enough to post URLs): ODD Vs EVEN FIRE - The first Buick V6 were the proverbial "V8's minus 2 cylinders". This produced uneven (odd) firing intervals. In mid-1977, Buick split the rod journals on the crank to produce even firing intervals. The easiest way to tell them apart is the distributor cap. An even-fire will have six towers, while an odd-fire will have eight towers with two blocked off. NOTE: An odd-fire engine will run, although very poorly, with an even fire cap.
Race & Monkey, That is an odd-fire HEI V6 distributor. Looks just like the one in my Skyhawk. Holycow's explanation was spot-on too.
Monkey, You have a PM. If everything is to your liking, I will pull it out of the car tomorrow (Friday).
