I just bought one of PorKen's cam timing tool and checked the cams on my '89 GT. The right side was retarded about 2.3 degrees and the left was advanced 4 degrees! That's a difference of 12.6 degrees of crank rotation between the two sides! While I realize unless I index the cams according to the WSM I don't exactly know where they're set I was amazed at the difference between them. BTW, I think he only has a few sets left. ****** them up while you can.

Agreed on how well Ken's cam timing indicator tool works.

I adjusted my cams with the factory tools and WSM method to factory spec-big PIA. Seemingly minute adjustments between the cam gear and cam make a large change on the dial indicator.

When I checked the readings on Ken's tool after the factory type adjustment procedure, it showed my passenger side was .5 degrees retarded, and the drivers side was 1 degree advanced. Those two numbers are now my baselines for those cams for matching the factory 0 degree setup and making any changes later on. Much easier than pulling the cam covers to make any changes later on.

I third that. One of my cams was retarded 7 degrees and the other was retarded 3 degrees.

Any performance gains after adjustment???

Keith,

No before/after dyno or g-tech, but the car pulls harder since the adjustment. I was way off before adjustment-I think it was close to 5 degrees advanced on one bank and about 5 retarded on the other. Much harder pull now, and boost starts building earlier in the rev range. As for a NA car, don't know, but it has to help.

Ok,ok. You got my interest-where can I find the cam tool.

thanks

Great idea of Porkens. Glad to hear someone has used it. I bought one but was waiting to hear of any gotchas or tweaking ideas.

I seconds that! where is it?

I have the PorKen tool & adjustable timing conversion for the early cars... but I bought it right after changing the T-belt. When it's time for a t-belt I'll go with HTD parts and make it adjustable.

I have (2) 32V tools left, and (0) 16V conversions.

When I sell this last batch, I will have (in theory) come out even on the development costs.

I am still deciding whether to make any more. (I have to order at least 20 at a time from the laser cutter).

Here's the manual if you haven't seen it before: 32VCamSetup1_0.pdf (380Kb)

PM or email me for more details.

How much are these wonder-tools?

Without calibrating the PorKen tool using the WSM procedure, how can you tell the two sides differ in adjustment?

I thought the tool was only good for precisely relocating the cams from the WSM calibrated settings

Ken,
I pm'ed you a few days ago, just making sure you got it. Thanks for taking the time to build this tool, BTW.

So far, I've only heard of the cams measuring +-1 cam degree when set with a dial indicator. 4 cam/8 crank degrees would be unusual, I would hazard.

Mine were off over 6 cam degrees, over 12.5 crank degrees, from each other. In reviewing my PO workorders I noticed at the last TB change that the mechanic had 'advanced cams 5 degrees for more HP'. But I don't see anything that shows the cam covers were removed to properly determine the advance and I haven't the faintest idea how he could have determined what 5 degrees advanced would have been. Thus I've always suspected the cams were out of sync, PorKen's tool confirmed it. Someday when I haven't anything better to do I'll index the cams, but until then I know I'm closer to spec than I was before thanks to Ken's awesome tool. Word to the wise, get one while you still can...
