Is this to much cam

I'm just giving my experience I'm using forty-year-old Springs with a bigger cam than that and having not one issue at all. The car runs perfect and drag races perfect. I'm just giving my experience that's all I've never seen a factory spring that I could squeeze with two fingers. Really a guy could probably go to a shop and just have the Springs tested. Or even build some kind of simple contraption that test how much pressure they have left in them. But it's been my experience just to throw in whatever I had and it works just fine especially with some kind of old hop up build like this. Know if he just got the block back from machine shop and was putting in all new pistons and rods and bearings and blah blah blah there's no way I would suggest throwing in some old Springs. But an 80000 mile truck where he is just throwing in a cam to see what happens?
I should do what you want to do this is just a form or everybody's giving their opinions anyhow and mine's not an opinion mine is my experience and yours is probably your experience you probably Broken Springs or had valves float that shouldn't have. I can tell you unless he Strokes that 318 and puts nitrous on it? A 318 ain't gonna set the world on fire in a full size truck no matter...
Here's a picture of My Time Slips from last Sunday with my 40-year old Springs and my 450 + lift. Can you shoot a picture of you holding one of your Springs between your fingers and squeezing it all the way down with two fingers?

It's not a question of breaking a spring. It's a question of keeping the valves under control. The cam he's suggesting is way bigger than the stock cam those 40+ yr old springs were made for. I've seen stock springs that old that you could easily push down with 2 fingers
