Thanks for the pics and sharing your experience .
Looked at pics of the sweep pattern from when I put the t&d set up on. Not nearly as short as yours. I thought they were acceptable at the time but obviously not.
Thanks again.
Yes, the pattern is pretty wide, but don't feel bad. You are going on the information you've been told in the past. I see that, and worse, frequently.
Something else that raises a red flag is the pushrod I see in the pic. You haven't given any cam or spring specs, but an inexpensive 5/16" welded ball pushrod is likely way too small/weak of a pushrod for your application. That can also cause some serious valvetrain instability. It becomes a pole vault for the rocker arm when the pushrod flexes excessively. You should probably have a 3/8" x .080" wall pushrod, minimum, but if you can share cam and spring specs, we can be more precise.
With a stout roller cam, I like to step up to a 7/16" pushrod like these from Smith Bros.
