Holley Carburetor Spacer
I have a 1989 454 CBB out of a Winnebago 35' motorhome. Has 50,000 original miles but the Quadrajet that was original to the motor is locked up tight so I got a Holly 750 and need an adapter plate-would this work?
how much of a hp gain will get with a 2 inch spacer on a 350 chevy with a 500 lift cam aluminum intake and flat top pistons, 600 holley carb?
