305 Build up. What would the gain be?
Just looking for a ballpark range on what kind of HP and TQ I might see from these? I'm looking for a nice little set up for the 305, that will give me more hp and tq, but not kill me on gas mileage that much.
SLP Intake Runners
SLP Cold Air Intake set up
Throttle Body Air Foil
SLP Shot-Gun Muffler
BBK Pully Set
JET Stage One Performance Chip
MM Throttle Body Spacer
Summit Longtube headers
removal of cat and all smog equipment.
Engine is an LB9. Bone stock.

probably put down about 220 hp to the wheels ...or around there. Sounds like a close build to a firends ...he nailed 227 rwhp ..with tuneing . I eould loose the chip though .... it on't do too much other than WOT stuff ...

Re: 305 Build up. What would the gain be?
The air foil, spacer and chip are a waste of money. Instead of that stuff you could do a cam swap and add some real power. I personally would not remove the emission stuff but its your car. I have found that there is no real gain in removing that stuff and sometimes it hurts the overall operation. There are good hi flow cats out there for cheap too.
