I wish I had learned about the camshaft availability about a month sooner when I had mine apart! Ah well....

Old lifters on new cam equals flat lobes!

I'll be surprised if that cam is still good, even if only ran for a few minutes, the first few minutes are EVERYTHING to a new cam!

Seen it done many many times, results were the same every time... Wiped cam!

It may still look visually ok.

-Enjoy

I am also looking to squeeze a few more ponies out of my IDI and would be very interested in seeing a before and after dyno with this cam.

Typ4, would I have to send in a core with my order or do you have cores and could send the reground one, we can swap and send our old one back to you for core charge?

So, I have a great cam supplier , he wants me to offer a cam to someone at a reduced cost but they have to do a before and after dyno comparo, same timing and injectors, maybe even 2 cams one on a turbo truck and one non.

He also said the lifters are ok to reuse if they are very smooth, and they recommended that they be taken apart and clean the varnish out so they will travel fully, that is what I did on mine.


The OB member with lifter trouble had a reman engine with non standard lifters we deduced after some discussion.

Have any of you looked into higher ratio rockers? That would be an easier way to increase lift & duration. I've never seen any advertised for these, but there may be one that adapts easily.
