I hope mine hold out until I can afford a 6.0L

 

I thought that I recently read that they were actually Comp springs...

 

post it.

SDPC posted that they were PACs

 

Last i heard they were PAC's, But i could be wrong.

 

What size cams are these good for?

 

We don't know anything about this though. I would blame this one on installer error before I would the springs. Look, hands down there's only 2 premium beehive's out there. The PAC 1518's OR the other one I would run would be the PSI LS 1511ML

Before pissing and moaning about the price, look at how much money we have stuck in these motors, it's not worth putting sub-par parts in.

 

+1 I want to know too. I was planning on putting some on my sbc vortec motor.

 

Can't remember where I saw it If SDPC says so though, that works for me.

 

I would fell comfortable running up to .600 lift with these springs. Anything higher and I would go with duals. PAC says they are good for .625. the 1518's

 

Here are my comp 918's. Broke in two right in the middle. Running Patriot duals now and love them.




For the price of those you could go ahead and get duals for 5 bucks more. IMO it is not a good idea to run a single spring with any cam the is not stock. If you are going to do a cam swap put up the money for good springs. If you don't have the money you shouldn't be doing the cam swap to start with.
