Ok i have had a set of stock modified rockers and loved them on my last grand prix im about to order a set of rockers monday im just a lil confused im going with the yella terra style roller rockers just need a little help picking the size out either the 1.90 or the 1.95 im not sure if theres any power difference between the to.

as of right now with the mods im working with 3.4 press on , headers should be in by tuedays, cat/res. delete, 42lb injectors, ported sc and tbody, 255 fuel pump, custom cia, 160 tstat, 104 autolites, msd coils/wires, intense shift kit,dhp tuned pcm

i have a set of ls6 valve springs not installed yet, thinking of going with 105s because im wonting to spray the car as well.

come on guys need help im wonting to order them monday so i can have them in by sat, i wonna go stang huntings :D
 


It won't much matter. The stress on the valve springs comes solely from the valvetrain and not through nitrous, boost, etc. So just make sure you're using the right springs for your rockers and everything else will fall into place.
 
The MSD stuff, fuel pump and res delete are all a waste of money imo. MSD will hurt performance if anything, fuel pump is not needed til close to 400whp iirc, and taking out the res will make your car sound like crap, as will taking out the cat.
 


I was under the impression the wires were better but stock seems to be quite alright for a while.

If you want a nice wire look for some ZZP's or PRJ's.
 
well lucky me i didnt pay for my coils or wires :)
the stock coils are actualy better it takes more power to really
make the coils do wat theyre suppose to do! no i guess its in ur own eyes
as fare as removing the res and cat bc i removed mine just put my headers on
lastnight and my car isnt loud at at it really sounds stock to be honest just
a lot more pull so im runnig a lil 3.4 with no kr :) so im not complaing waiting on the yella terras now the droppen to the 3.2
 


mmm i dont know any that do either :th_nervous: i just decided to take mine on out figured it would kinda give it a lil deeper sound wrong really didnt change anything ol well done now right oh headers yea i have the all to famous headers they are from dna motoring mine fit pretty good besides the o2 placement bad design but got it all straight now they look good sound good cheap and no leaks :th_winking:
 
FWIW, glad you didn't go with teh coils. Never heard anything bad about the wires.

MSD coils: seem to break down and start giving high rpm misfires after about six months to a year. Stockers don't typically do this.

ZZP Wires: These are so bad that I advise people who already bought them and bring them to me for an install that when they get misfires they should swap back to stock or something like Autolite Pro wires. Send the wires to ZZP for free replacement and sell them to someone else. Speaking of which..I have a set in a sealed bag. Anyone want to buy them cheap?
