I have been reading this thread with interest....
Thanks for your thoughts and observations.
I have also read good and bad comments over the years regarding the quality of engbldr’s quality of parts sold. But I've read good and bad comments on just about everything I’ve researched on the internet.
It is certainly possible I got bad or defective camshaft. And, there have been some bad experiences with this camshaft posted here.
Yes, I have considered several possibilities. Over the years I’ve purchased aftermarket parts from different sources and gotten bad parts. I think it is way too common with aftermarket parts, probably most coming out of China.
My comments about the visual appearance of the cam are based on seeing 3 other cams for a 22. The other thing that caught my attention when I installed the rocker rack was how far off the rocker pads were to the cam lobes.
My stock camshaft has rocker pad to lobe misalignment of .030” smallest to .068” largest. Not one lobe was worn perfectly across the entire width. But, the 261C cam has several pads that are off the lobe between .108” to .112”, and I posted photos of this. So I immediately felt there could be a “quality control” issue here… a bad casting. Even though Tod at engbldr said it's OK, I still don’t think the alignment should be off that much.
The old adage, "You get what you pay for" has been shown to be true with Toyota parts. Engbldr's prices are lower than most sources for aftermarket performance camshafts for the 20/22s.
I mic’d the camshaft I removed from the old head, and all lobes heights are within FSM spec.
I was not able to remove the rocker rack today, but I will in the next few days.
I wish I was running a carb'd engine!
