Review on ๐ŸŽ๏ธ Allstar Performance High-Flow 0.500" Carburetor Spacer for 4150 Series by Jason Rosekrans

Revainrating 1 out of 5

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 300ยฐC (572Fยฐ).

Pros
  • Carburetor and replacement parts
Cons
  • Hard to tell
