What to do With My MK Cams
 

I've read every post that FF started with his cams and I don't know with my MK cams. So far I have not had any problems yet do I pull the cams out or should I leave things alone??? I only have about 10 hrs. on them right now.

Why don't you call the cam manufacturer and tell them what the cam is and what springs you have and see what they have to say. Then pull the distributors and run a bore scope through the hole and see if anything looks suspect. Then decide what to do from there...

I hope you realize that there are about 5-10 peeps on the bash MK cams bandwagon and I'm not saying that they didn't have issues.
There are also 100's of others that are running MK cams with good results.

I've got no dog in this fight so carry on

If you tore your motors down based on things you read on the internet and speculation, I think you'll have them torn down every year. Who does that...:party-smiley-004:

I have a few more hours than you do with Bob M cams and also have no issues. I have called Cam Motion and I am go to go as far as I am concerned. My cams are not a lot different than a 525 efi and everyone seems to like them so I am not going to worry about them.

What are the specs of your cam?

I have 496s, heads are AFR 305s cams lobe separation 113.1 intake duration 237.1 lift 663 exhaust duration 243.5 lift 654

Very good point !!

Many more then a handful with issues, and most seem to be recent and specs like mine, a simple test would be to yank a distributor and you can at least see the 4 last lobes visually, takes 10 minutes you will know if you have issues, if it looks good run it till refresh time, many of the guys not having issues are less agressive on valve train... That's why no issues, my valve train is beat to you know what at 65 hours...

My MK SBC cam went in 2007 and was still running when I sold the motor to donzi matt a couple years back. Cam Motion billet roller 234/240 .580/.568 112+4. When engine was rebuilt last time, cam and lifter lobes were normal. Morel lifters. Motor made great power and GPS speeds were above expected for the setup. Like mentioned above inspect thru the distributor hole and if happy with performance leave it alone. My .02
