These "rams horn" cast iron exhaust manifolds were patterned off the 1962-63 327 Corvette but are not OEM remanufactured manifolds (no casting numbers). 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.
Summary: I broke my left side original casting. Ordered these to replace. Well built and fit perfect. Probably better made than originals. They are original style castings in style and fitment. They are not number matching castings but that is not what I was looking for. Great price and value if bought as a pair with hardware. The short bolts to head were missing from hardware kit. Everything else was included.
Yes, I recommend this product.
Summary: Manifold was the same dimensions as my stock manifold as was well made. the bolts that were included bottomed out in the head because they were about 1/2 inch too long. I was able to use the existing bolts for installation.
Yes, I recommend this product.
Summary: Installed on a 67 Chevelle 327. wanted something different. Instead of headers that you have to make clearances. 2 1/2" runners are just the same as block huggers.
Yes, I recommend this product.
