I hope this is the right section. I'm wanting to do a camp swap on my 2000 chevy silverado that has a 5.3L in it. I was talking to a local shop owner about doing the swap for me and tuning my truck, but he wasn't 100% sure which ration rockers I had on my truck. He is used to dealing with f-body cars and he said that he doesnt have a lot of guys with trucks that get things done. I was just curious which ratio rocker arms my engine would have so I can decide on the cam's lift. Thanks

 

Your rockers are 1.7

 

That's awesome. The guy that I talked with said he thought they might of been 1.8 but wasn't sure.

 

indeed 1.7

 

If your truck was modified when you bought it, there is a slight chance that your rockers could be 1.85 SLP's. They look identical to stock.

 

My truck was bone stock when I bought it. I have since only lowered it, added a full exhaust, and a dyno tune.

 

You have 1.7's then.
