Cylinder volume box in the Engine>General tab

Get ahold of one of the injector sizing spreadsheets
and get the flow rating, rating pressure values for
the new pieces and the originals, for the IFR table.

I told you it was a lot of math. I got all the numbers figured out. People in here want you to learn how to do it and not just give it to you. Call me to set up an appointment

<barbie voice>"math is hard, lets go to the mall"

the reasons why we give out principles not results is because noone learns anything from it. also, saying '408' doesn't mean much to me. give me bore and stroke, and then i can show you (it is very simple, i hope you passed your 7th grade math) how to get it precisely done for your setup.

if you want the whole writeup for how to tune for injectors, increased displacement, 90/90 and such, click on my sig and look for 'idle tuning' article.
