Hi all I don't know if it is my poor experience with cam... but this is the second cam I receive from isky that is marked wrong... check original cam mark point and isky on the right...the third cam I got, the mark is on the left.... timing gear mark is always down, is that a common problem? thanks
So it's the timing mark on the cam gear that's screwed up? If it isn't, and you are running the 'normal' looking dizzy (as opposed to the crab that mounts to the front of the timing cover) which it looks like you are (with the drive gears installed) how does the distributor know where the timing mark on it's drive gear is? Please don't misunderstand I'm not being a smart ass here. I am no flathead guru (it sure looks like a Flathead V8 cam to me) so maybe I'm missing something, but If the cam to crank timing is correct, and you drive the dist with a gear (like in your pictue) what does it matter where the timing mark on it is (why is it there in the first place)?
i guess im not following. use the mark on the cam gear to set cam timing. the hash mark on the dist drive is not relevent to timing the engine.
ok ok ok, my english is not so good... but I try it You got a mark on the timing gear! and a mark on the cam (on the distributor gear). If I follow the instruction my timing gear mark have to be down and set with the crank mark! then , if I check the mark on the distributor gear, it's wrong! and the cam is not correctly in place! the engine won't start, I have to remark my cam correctly!
When you stab the cam you allign the "slot" on the cam gear with the "dot" (I think) on the crank gear. As stated before cam gear can only go on one way and that mark on the distributor drive gear means fuck all. After cam is in you turn motor to TDC on No. 1, drop in the distributor monkeying with it until the rotor is pointing at No. 1 wire as it slides in. Button it all up and off you go. Serious - that mark you're looking at means nothing.
I am new here but I had this problem about four years ago. I ordered a adjustable cam gear from a place called Red's Headers and never had a problem since.
Alright - you seem convinced something is wrong and are determined to "fix" it. So... did you do something wacky before like redrill the cam gear when you found out the holes didn't line up? Because those holes are supposed to do that and only line up one way. Seriously not trying to be a douche - just looking at what you are doing - and saying - and trying to help you figure it out.
Ok, but how can you explain, that the engine don't start? i have put a few cams on flathead engines with no problems, but those 2 last cams had problem, beleive me... On my coupe the cam was set as you describe and as I always do, and never get trouble.. weird weird...
No, no, I haven0t redrill something, But what I'm thinkin now, is maybe my timing gear in aluminium in not drill correctly? anyway, after find the correct position the engine start now...
Sorry but, I'm not so sure I believe you. This is where you set your timing. And again, the mark on the distributor means nothing. So my question is, where are the lobes pointing on each cam when you point both cam gear marks in the same direction?
THIS IS EXACTLY WHAT I'M TALKING ABOUT. Just stop man. Put it away for a day. I know you put a lot of work getting that blower on there. The popoff valve, the idler pulley. I know your motor - paid attention. Just wanted you to know that so you don't think I'm some blowhard just trying to be a jerk. I'll put money on this: Nothing is drilled wrong. Nothing is marked wrong. I seriously think you need to just stop... and start over. You've worked too hard on that motor to cock it up over this. Take pictures as you go and we'll walk you through.
Hey Kevin, keep cool... Here is the problem, the lobes was not pointing at the same place! My first cam , if first cam lobe point up, the new isky lobe point more or less 1/4 on the left... That was what I try to explain with my survivor english.... sorry...
I've been told GMC 6's have been having a problem with the timing marks being off (mislocated) on their aluminum cam gears. Could this be the same problem?
Hey Kevin by the way, it was your post back in in the early part of 06, that made a flathead rebuild easier for me. So thanks Dude that was a great thread.
The gear will only go on the cam one way. Line it up on the crank gear. Check the valves at number one at TDC to make sure its all correct. Disregard the distributor gear. When you have the motor all together, it should still be at number one TDC, then put in the dizzy with the rotor pointing to number one on the cap. This is also the time to check the timing mark on the front pully to make sure it is correct.
As Kevin said, I have check the lobes, in same position of timig gear, the lobes are not in the same position.

Are you using the same Cam gear? Or a new one. I'm sorry if you stated this alread but it wasn't clear to me.
