Hey guys I'm kinda new to the lt1 world but quick question. I just got 96 z28 and after I put about 200 miles on it when shuting off the engine and it stops rotating it let's out what sounds like a little air purge from around where the intake and throttle body is. I just wanna know if this is normal. I don't think it's a leak in the intake seal because my rpm aren't fluctuating. If anyone has any input it would be much appreciated. Oh the car only has 51000 miles on the original motor.
