I believe you commented on your 261C in earlier posts here, so would you choose this cam again?  What does your butt dyno say about it?

Most of the people I've read about or spoke to made their cam change during a rebuild, so the actual "change" in performance between camshaft profiles is difficult to determine.  As I mentioned, I am planning to do some cam swaps after this engine is completely broken in, tuned, and running like I think it should, so I can "feel", and possibly chassis dyno, the results of the change.

One thing with this cam that I'm not happy about is the fact that 6 of the lobes are misaligned to the rockers - off by as much as .100".  I don't believe it's the rocker rack, but I have not verified that.  It may be just lack of quality control during the casting of the camshaft?  I am curious if you have noticed this with your 261C?  Next time you have the rocker cover off, would you mind checking out the alignment and letting me know.

Next time I have the cover off I can let you know. I actually made the cam change during an engine rebuild, but my old engine was perfect as it came from an automatic truck so the engine was still tight. I had asked Ted for the cam suggestion and I don't know if my expectations were to high or what but I'm pretty disappointed in its performance. The stock cam kicks its but I think. I can barely get this cam to 5k without it running out of steam. I typically run it at 3500 going down the road but when trying to get on the highway (I live in Utah at the moment so speeds are 70) I just don't like it at that time.
