Review on ποΈ Allstar Performance 1" Hi-Flow Carburetor Spacer - Boost Performance with the ALL25981 4150 Model by Sean Reddy
Works on 1750 Throttle 4150
I used this gasket on a customer's engine (499 Chevy) who liked the 4 hole 1 inch spacer best on the dyno. Most of the less expensive spacers are for the 1-11/16 throttle body used on the 4779 etc but not the 950hp used on this engine. This fit and worked perfectly.
Pros
- Easy Install
Cons
- I won't say anything
