hei dist conversion tomorrow...one ques. though... - Off-Road Forums & Discussion Groups

I have finally broken down and ordered a brand spankin new HEI distributor to put in my 225 tomorrow. I have read and reread the tech tip on the swap, and feel pretty comfortable about the project. However, I am confused about one thing, it says to make sure and check the firing order of the auto the distributor came out of because it might be different than my 225. Ok, am I missing something here? If the rotor spins in a circle, won't the order be the same? In other words, my wires will remain in the same patter on top of the cap?

By the way, I am in need of a set of stock springs if anyone has any. If not, has anyone ordered them from amcjeepparts.com?

It's the odd/even thing you have to worry about. RRich says to make sure they rebuilt it with the proper odd-fire parts and not a combination of both odd and even.

You might want to review this to make sure you have the right parts: <a target="_blank" href=http://tellico.off-road.com/ubbthreads/showflat.php?Cat=&Board=offroadjeepjeepster&am p;Number=818069&page=2&view=collapsed& sb=5&o=0&fpart=all>http://tellico.off-road.com/ubbthreads/showflat.php?Cat=&Board=offroadjeepjeepster&am p;Number=818069&page=2&view=collapsed& sb=5&o=0&fpart=all</a>

that certainly makes everything very clear. I ordered everything new from Advance and told them to take numbers from a 76 Buick Skylark Odd Fire, so hopefully they will be the right parts, but I will print out these pics to take with me and double check. Thanks!

If it's going on with the 2G carb -
Be sure to replace the HEI advance diaphram with a Crane adjustable advance, install the small limiter cam that comers with it, and follow my instructions for adjusting it properly. Otherwise you won't like the way it operates, stumble, less power etc.
Last I saw those instructions were on the AJC Southwest Chapter's website.

Make sure you look at the dist and cap closely, and if after a couple of minutes you scratch your head and wonder how it works, then it is an odd fire. I ordered a new one from advance (30-1693) and it ended up being an even fire. Found out after I could only get it running on 4 cylinders. Got another under the same number and it is the right one. I read the posts and Rich's instructions many times and I still neglected to verify that I had the right parts.

well, I picked up the parts this afternoon, and everything looks just like it is suppose to according to the pictures. I guess I will start on the removal of the old Prestolite tonight...I am looking forward to seeing how the HEI makes it run...

It will help if you know which one to make #1. Looking at the top of the distributor you will see four in a row, then a space, then two in a row, then a space. Mine is in the third position of the four in a row going clockwise. Everyother one will work for the #1 position as long the rotor is lined up to that post and the engine is top center #1. I hope I explained it so everyone can understand.

thanks...that explains a lot...wish me luck!

Thanks Reno - that really helps folks from getting it "out of sequence" and having that sort of letdown.

Maybe that should be included with the HEI instructions too. Maybe mark those 3 as the ones to use for #1.

Is anybody collecting all the HEI stuff and putting it where it can be located easily?
