Rockers

I've been looking for roller rockers and came by a set that was just used for a dyno run. They are 1.52 ratio and I was looking for the 1.6 but after reading up on stock rockers that I always thought to be 1.5 I have read is a few online articles that the stock rockers are less than 1.5 and can be as low as a 1.43. With that in mind the 1.52 rockers should give me a bit more kick. Anyone have any experience with changing the stock rockers to the 1.52 and noticed any performance increase?

I dont think your going to see much of a difference in performance. Your only going to see roughly .007" more lift compared to the 1.5 ratio. But the jump to the 1.6 as you know will make a difference.

Thanks for the input. I have read that the 1.6 can cause a hp loss and the only way to see what works is a dyno on each set up. It's a daily driver so for now I'll be happy with the 1.52 roller rockers since I'm getting them for less than 1/2 retail.. I'll keep on the lookout for the 1.6 and give them a try when and if I get them. I was surprised to read about the stock rockers not being 1.5.
