Here is my idea to save you big bucks, pass emissions and gain considerable power, Buy some LS1 or 5.3 Truck Head Cores, send them to Bo White for his Econo port and polish job. ( Cores 300.00 - 400.00). Porting will Run 300.00-600.00 depending on what you want. Contact Ed Potter at LPE, ask about the GT2-3 Cam and find out if it will pass the sniffer, im pretty sure it will. The Cam is something along the lines of 207/220 on a 118.5 LSA. Idol, sound and drivability is completely stock. People have been seing 30 RWHP increases Cam only. The Cam, with LS6 springs will run you 400.00 as a package from LPE, maybe less so now we are at 1400.00 not including shipping. Then, purchase a set of Mac Mid lengths with Cats for around 600.00 i think. So were at 2,000.00. Send your Throttle Body to Cammin Beast, 75.00 dollars, now we are at 2,075.00. Buy a used Lid, 75.00 and a SLP loudmouth 2 from LM performance. That puts you at 2,500.00 not including shipping or install and i would bet you will see 380 RWHP and 360 RWTQ with a tune while passing emissions... I am sure others can come up with something better, but it would be a great daily driver emissions/budget set up!
