They feature the big 2-1/2" diameter outlets and have provisions to accept original alternator type brackets. They are the perfect addition to a retro 327 style build: 365hp L76, 375hp L84, or 350hp L79 (all came with 2-1/2" outlets). These Chevy ram horn manifolds are copies of the original1962-63 Corvette manifolds and can be used on almost any small block engine up to 1999. The cast in brackets are for the water tank on the drivers side and generator bracket on the passenger side. These can be cut off and smoothed per customers preference. These are a square port configuration with 1-5/16” top to bottom and also side to side. Compare to your head port size for compatibility.

If it is not required or needed, it can be machined off if necessary by the end user / installer. Ports measure 1-5/16” side to side and top to bottom Has sufficient material for porting/matching to your head.If using on original '62-'63 Corvette: Generator mounts on passenger side (right side, 4.5" bolt centers)Water tank mounts on drivers side (left side, 3.5" bolt centers) These manifolds will bolt onto the Chevy small block engines up until the advent of the LS series engines in 1999. They are copy of the stock 62-63 Corvettes where the passenger side manifold is cast with the boss for the generator and the drivers side is cast with the mounting boss for the water tank. This is reverse of the later years and the possibility of adapting to different accessories such as the A/C compressor would be up to the installer. These are specific to the 62-63 Corvette for accessory mounting. No issues with high compression engines have been noted. These manifolds will work with the standard port small block Chevy engines. Fit to your application can be verified by some basic measurements as follows: * A” dimension from the head to outer edge of the collector flange is 4-1/32” * Center of head mounting bolt to bottom of collector flange is 4-3/16” * Center of head mounting bolt to highest point of manifold is 2-3/4” * Right Manifold: Accessory bolt boss center-to-center is 4.5" * Left Manifold: Accessory bolt boss center-to-center is 3.5" The outlet is directly below the center two ports on the head. You will need to verify clearance on your steering and cross member for exhaust hook up.
