2-1/2 collector uses standard reducers or tight tube extensions. Includes gaskets and bolts shown in the picture.
Note: The port size is square and large enough for most round port heads. It measures about 1-1/4 and should be sufficient for most small block cylinder heads.Will clear most straight and angle plug heads. Will not work with GM "fastburn" heads.
These fit great in a variety of street rod and vintage truck applications (particularly those with Mustang II-type suspensions). The collector on this is directly below the center 2 exhaust ports.
Measuring from the center of the middle header bolt hole to the bottom of the collector flange is 4.5. The outside diameter of the collector flange is 3 ¾. The alternator mounting depends on the bracket. Powered by SixBit's eCommerce Solution.
