injectors... they are way over the duty cycle......

 

So should I go with 30# or 36# injectors?

 

36#

 

I would definitely do the injectors. As for the throttle body, with the work you have done a larger unit would be of some benefit.

 

How about some headers with a primary bigger than 1 5/8?

 

i dont think ur pushing the limits on those headers yet....

your next mods should def. be (in this order)

injectors
port the intake
bigger throttle body
1.6 roller rockers (you might have these already, but I didnt see them listed)

edit: where in KY are you located? I'm always looking for people to cruise with

 

yeah I planned on getting Longtubes when I get my LE heads.

 

Thanks man.
