Anything wrong with sticking with the stock rocker arm ratio (1.7:1) on a turbo 408 lq9 build with 243 heads? The cam is .232 .240 .595 .608. which would mean (.595x1.7= 1.0115). I plan on using some comp shaft rocker arms.

And Im not sure on pushrod length either. Is that something to be determined once I have everything all together? If thats the case then I will use this method https://ls1tech.com/forums/generatio...l#post15796641.

I try to research as much before I ask. Thanks for the help.

I'm using stock rockers with the trunion upgrade and PR length gets checked when it's assembled

Umm... those lift values you were given already had the rocker ratio figured in.... .598/.608 would be valve lift.... not lobe lift....

Thanks guys. Trying to soak it all in... pardon the FNG questions.
