I work on duty and am online all the time...thank you population 4,000 and dog shift....no one out and about after 10pm

 

as the op said he has bigger cams and ported heads. my recommendation would be this, something with a 4in. intake duct, 90mm maf, and 75mm bbk throttle body, you get a custom tune for all that and you will notice a big difference. i think specter's intake is 4in. you could probably do this all for under $400 and that's including the tune. however this is the best you could do (in my opinion). but all the other posts are all great options. it's up to you. hope you enjoy what ever you go with.

 

Lets see some videos of this thing with the head/cam work!
