Definitely a great product. Very happy with this purchase. If I ever need another one, I'll definitely go with this same brand.

If you need more clearance this is for you. Works great for any 4150 holley carb or any efi 4150 elbow as well. Highly recommended.

I HAVE NOW INSTALLED 4 OF THESE THEY ARE SIMPLY THE BEST! AMAZON SELLS THEM AT A LOWER PRICE THAN SUMMIT RACING. ALWAYS USE A MR GASKET 1 INCH SPACER!

Installed between Edelbock intake and Holley carb to eliminate vapor lock caused by heat. Studs were too short so had to buy longer ones but product is high quality.

Love it. It added the necessary clearance between carb and manifold to use a 50cc accelerator pump

Super as always with mister gasket

You can feel the extra horse power out of this spacer and it also helped my carb from vapor locking
