Review on Chevy TBI Open Spacer by Trans-Dapt - Model 2633 by Brendan Baker

Easy installation In fact I was able to simply unbolt the TBI from the intake port and slide the gasket with the gaskets in between without disconnecting the throttle vacuum lines etc. made in less than 30 minutes. I have a relatively quiet exhaust on my 1991k 1500 with a 5.7 V8 engine and I definitely noticed a change in tone after installing the spacer. I really want to tow my camper and see the difference before and after, I can tell the difference in acceleration torque already in daily driving, it all affected throttle response
