Just done the cam swap about 150 miles ago. I was putting headers on tonight and while I had the valve covers off I thought the springs looked strange. Almost all of the springs on the very top coil that sits against the retainer is broken. Why would it of done that? The cam is the Comp 228/230 571/573 112lsa. The springs are comp 918. I also have the 7.425 pushrods. Is there a right and wrong way to set the spring down on the seat? I don't know what to do.

 

Why did you go with longer than stock pushrods?

 

the guy at comp cams told me that the base circle was smaller so i would need the longer pushrods to compensate. Maybe he was on CRACK!! do ya think that is why the springs broke?

 

Hopefully you didn't get defective springs. How much did you compress them during the install?

 

Ok next question, what rockers? and how did you set them?

Check your pushrods and see if some of them are bent.

 

I have the stock rockers. I didn't set up the springs because I was told that you can just put them on and go.

 

I asked about the rocker set up because with a different base circle cam and longer pushrods you need to first check for lifter preload to see if you need to shim your rocker stands to get into the middle of their operating range.
Your heads are stock?

 

yea the heads are stock. never even had them off.

 

What procedures were followed for the spring install??????

 

 

This is the reason I stayed away from 918's. I have a friend that broke some on a mild GT2-3 cam. The second time he broke one it dropped the valve and he ended up having to buy another engine.
