Rochester 2GC info

[NORMAN BARNARD]

guy's that's an old trick from the 60's , but it reduced the booster signal . brad urban from the carburetor shop also tried it years ago but with limited success.

for our circle track customers that have to run a 2gc or a marine carb. we designed a
a cnc'd alum. insert that replaces the original restrictive insert. booster signal improved as did the total cfm.

the above may not be legal per your track rules. but some times it pay's to think outside the "box".......
