Pypes Race Pro install on 66 Chevelle

I used the 2.5 pypes race pro kit made for a 64-72 chevelle. The motor is a 5.3 LS with 862 heads and a sloppy stage 2 cam. Speed engineering 1 3/4 headers. The car is not tuned during this video and is just in the Holley start up tune. Any questions don’t be afraid to ask
