Shipping to Nashville would be roughly $50 each way for the pair.

I bought the tool and swapped the springs myself. It was super easy. I'm just about ready to install everything.

I just need to figure out pushrod length.

The Trick Flow GenX 255 top end kit comes with 7.750 pushrods to use with their heads on a stock LS3/L99: https://www.trickflow.com/parts/tfs-...tcombocontents

The Texas Speed 1.72:1 rockers say they need 0.140 shorter pushrods.

Quote:

*These rocker arms will require you to change your pushrod length. It is approximately .140" shorter than what you are currently running.

Do you have a stock L99 with TFS GenX 255's and the TSP 1.72:1 rockers laying around that you could verify pushrod length on, @Punisher_ATX?

Don't forget to checkout the PRC 260 heads! We can mill to match the customers cam & recently someone made 540rwhp on the camaro5 fb page!!

For future reference, the pushrod length measured out to 7.575" for the LS7 lifters, TFS GenX 255 heads and Texas Speed 1.72:1 Roller Rockers.

Done! Just needs tuned..

Had to clearance the valve covers because we had contact with rocker arms, but other than that, it went well.

Still more left in it. Shifting at 6,600 and bouncing off the rev limiter. left at idle, on street tire with traction control on.
