Timing issue
hi guys, have a little problem with my time the camshafts are on spot the crank at TDC with a long extension. All the marks I made previous to disassembly the rockers are in spot. But the car rev's like retard, put the Distributor all the way advanced and works better.

forget to mention the car was acting this way before the rocker and exhaust cam swap. I did the swap because the cam and rockers have excessive wear and I think this can be related.

Re: Timing issue
It looks like you have adjustable cam gears. If they were set for excessively worn parts, wouldn't that make fresh parts be close to a half a tooth off with the old position of the cam gears?

Re: Timing issue
probably if you left the old setting with new cams they where a little off. But since in didn't have other set of ITR cams, I put GSR ones with the gears dialed at zero.
I think this what you mean excuse if not.

Re: Timing issue
Actually the more I thought about it, the more my thought doesn't seem to fit.
I was thinking the wear would change positioning of the cam shaft, but really it's only going to affect how far the valve opens, not when.
Ignore my comment, it's not relevant.

Re: Timing issue
Since the cams are adjustable, the real question is where are the cam lobes for #1 when the crank is at TDC on compression stroke. That will tell if the cams are out of adjustment.
Might be a good idea to check them at each of the 90 degree points as well.

Re: Timing issue
hi, trying to solve this problem, put the timing light with the cams at zero and spot the crank mark perfect but the car rev slowly and chocking. Put the intake cam gear at 5* advanced and the engine rev's but it's off on the crank.
This engine always be at zero with the lines on spot the only I changed was the rocker arms which not affect time and a GSR exhaust cam instead of the ITR but line perfect.

Re: Timing issue
Did you see them off? Please point me which of them to try and reset them.
Also if you see my first post second photo you can see how the lines are flush with the head. Maybe is the angle maybe me.

Re: Timing issue
After some research and talking with the guys of forced induction and drag.
They pointed me into check the cams grooves, keys and the gears key ways.
The Fidanza cam gears that actually I'm using have a lot side to side play with new keys. So ordered a new set of titanium GE gears, in hope this solve my problem.
