i have an 89 iroc 350tpi is there a way to bypassy the coolant hose on the side of the throttle body that would free up a few horse power

 

Yes that would be a throttle body bypass. When looking at the engine from the front you can see one hose coming in from the left and another hose on front bottom right. You connect those two hoses together. There is detailed instructions on this in I believe the tech articles page here https://www.thirdgen.org/newdesign/t...ntbypass.shtml
