Review on 🏎️ Allstar Performance High-Flow 0.500" Carburetor Spacer for 4150 Series by Jason Rosekrans

February 10, 2023

Do not use!: Spacers and adapters

My photo shows a problem after 3-4 hours of use (multiple sessions). It was mounted on a Holley 4150 (4801-1 to be exact) and aluminum intake manifold (1971 Chevy Corvette C3 LT-1). Of course there were aramid pads (Victor Reinz) on both sides with heat capacities up to 300°C (572F°).

Pros

Carburetor and replacement parts

Cons

Hard to tell
