Distributor indexing help
Posted: June 13th, 2018, 5:11 am
I have searched and I am not finding a 100% conclusive answer...
I am working on getting my 4.6 finished up and I am having trouble figuring out the distributor indexing. I got this engine in a series of boxes and this is my first 4.# build, so bear with me if I’m missing something easy.
I have an aftermarket cam and I think the indexing is off just a little. I have read and found the procedure for pinning the rotor in place, but I can not figure out where the pin would go and I can not seem to find a picture of it. I have read about using a punch or other tool to lock the rotor, but I just don't see where it would lock in. I am attaching pictures of how the distributor sits right now. I took the wheel part off to see if I could see a place for an alignment pin and I just don't see anything lining up. What am I missing? This distibutor looks like a older renix but was on a 92 HO.
As best I can tell it is 8-10 degrees off of what is factory indexing, which brings up up the other question. From what I can tell the timing is controlled off of the crank sensor and the cam is simply used to verify cam phase and just has to be inside of a set parameter. So, the question there is, what is the parameter tolerance? Is this picture close enough? It lines up with the #1 terminal, so it is very close. I’d rather not grind tabs off.
Cam is a Howards I bought from Titan Engines if anyone knows how the indexing is on those. They claim to have no issues.
Any input or pictures are Appreciated.
