Is this to much cam

Tired springs + higher RPM = float

Simple as that.

So your tired springs may control stuff to 4500 rpm and a new set might hold them to 5200, which one is going to have more usable power if needed. Plenty of articles and test showing exactly that out there. The 340 dyno derby is one of them where the engine made a bunch more power with a valve spring change on a comp xe268 from stock 340 springs. Personal experience where there is no data to support an A-B test is nothing more than, it worked for me. Was it optimal, probably not. Plenty of people penny pinch and have decent results. I do it myself, just not in the valvetrain/springs. Maybe the next cam can use the new springs too, gosh what a concept.

Breaking a retainer, you grasping at straws? LOL I won't make what I'd like to comment about that statement with an OEM 340 spring. Keep at it because sometimes it's better to put the shovel down and step away from the hole. :)

If 50 bucks breaks the bank on a cam change or overall build, maybe some thought needs to be placed on where it's best to spend any money at all.

Don't worry, after this, I won't see your response... :) It's where you should have stayed from the as time.

Have at it.
