I have a guy here at work that swapped a 350 TPI into a '30s sedan. He is wondering if removing the EGR valve will improve performance. Any ideas?

Unless you disable it in the chip, I wouldn't do it. It is going to change the fueling, when the EGR valve should be open.

Do you know where I can find literature/diagrams on how the lines and hoses are routed on the TPI. Vacuum and cooling on the throttle body, etc? Thanks!

Should check where the motor came from and look up an engine schematic for that. We are doing the exact same swap right now. We have a 40 GMC truck little streetrod that we are putting in a 350 TPI L98.

EGR IS GREAT! Better milage, lower emissions, AND DOESN'T HURT PERFORMANCE AT ALL!

Yeah! Only reason I'm not running one is because there is no provision for it in the stealthram.

That's what I thought but I figured I would ask you guys. You're more familiar with the TPI engines than I am.

I removed egr on my '85 Z28 TPI with no noticable effect.
