I have jet hot lts,true duals,slp lid and an asp pulley.I'm about to do a 224/230 598/609 112lsa.With 1.75 comp rockers.What kind of number should i expect with a nice tune,and i will be spray 150,or 175 with that.The car is an 98 z28 with an m-6.What kinda number would i gain with an better intake?

 

Nobody wants to take a guess?

 

I bet no one has guessed because of your rocker choice. With that grind you are probably going to have to have valve reliefs or fly cut if you plan on running anything other than 1.7 ratio. You might want to re-think your cam is all I am saying if you are dead set on those rockers.
FWIW:
I have a 224/230 cam on stock rocker ratio, and it is plenty bad ***. definitely a pretty good nitrous grind though.

 

598/609 is calculated with the rockers

 

ttt Just wanting to know some numbers.
