my camaro is running 13.80's right now im am looking to step the car up so i can run th EFI 13 NMCA class so i need to get it down to atleast 13.20 I have some money to spend and i am open to all opinions. Right now the car has a performance resource chip, a borla cat back, and gutted air boxes with k&N filters, and i run th car on some m/t slicks. It is also pretty heavy 3650lbs so any weight saving tips would come in handy too. keep in mind i still have to drive the car every day on the street
Thanks

I would say that a good set of 1 3/4" headers, a 2400 RPM or so stall converter and maybe a cam would get your car for sure down to the low 13s. Also port your plenum and base and get a good ingnition set up.
