Throttle body/vacuum line questions on a emissions deleted set up. (pics)
I'm in the process of building the top half of my L98. I ordered some AFR 180cc heads, and I'm porting the intake/plenum/ 52mm BBK TB, and will be getting some ASM runners. My question are the top and bottom ports in the TB (pic) function? I'm going to delete the egr and block it off. The smog pump has been gone for 15 years already. What vacuum lines do I need or not need? The bottom port is for the IAC which I'm sure I will need when the blades are closed. Thank you for any info and tips. I did some searches but I'm finding contradicting info.
Work in progress. Im going to polish it to a good gloss yet.
