Hey first time I am on here I am a bit of a novice with this just really getting into LT1's. I have a 95 LT1 with a high performance Cam, Jet hot headers, SLP Loud Mouth exhaust not cats, K&N Cold Intake and low temperature thermostat.  I am looking to keep going but not sure what next step I should take.  Does anyone have any good Ideas I was thinking about a 58mm throttle body( is adding the air foil worth it?), underdrive pully's and 3.73 gears. Does anyone have any other suggestions.  Are all the bolt ons worth it or is it better to head in a different direction. I am also looking for someone to tune this car and work on the programming but I live in the NY Metro area and knowone works on LT1 motors?
