      L92 header size?

      How much performance would I be giving up if I went with a 1 5/8 header primary as opposed to the 1 7/8? For example, the street and performance shorty (1 5/8) and SW long tube (1 7/8). This is going into my 68 camaro. Any input would be appreciated.

      Chris,

      Shorty headers are usually a waste of money. They may look better than factory exhaust manifolds, but rarely perform better.

      The real headers from SW will increase horsepower. The faux headers from S&P probably won't.

      1-7/8" preferably or 1-3/4" will work well too.

      We have been using the Edlebrock 1 3/4 to 1 7/8 step headers and mounts with much sucsess and they are priced real reasonable.

      So Frank where do the Edelbrocks place the engine/trans in relation to the original mounts?

      I'm using this set-up in my 69 Camaro and it placed everything pretty much in the "stock" location. At least after bolting everything in the tranny mounts lined up

      How is the ground clearance? Could you post some pictures if you have them? Thanks.
