Review on πŸ”§ Swirltorque TBI Spacer for GM - Trans-Dapt 2533 by Anatoly Yorgason

Revainrating 2 out of 5

The installation effort is not worth it.

Installing the product proved to be a very difficult task. I put this on a 4.9 liter Cadillac OHV engine. I had to cut and bend the brake booster pipe just to clear the EGR valve, which resulted in the engine being stuck on full throttle starts. When I went to remove the gasket I found that the threads pulled out of the block were stuck on the steel mounting bolts. On the plus side, I was able to replace my old leaking TBI gasket! Thank you transdap.
