66 GTO, tripower. Center carb has .056 jets, .068 on the other two. Should I go to .066 or so on the center carb?
If I buy new jets, how do I order them? Current jets are type 'B'.
Thanks in advance.

What is your engine combo now, stock, mild perf? And what are your driving needs, cruise or drag? Email me at [email protected]

Most factory 66 tri-powers had 69-63-69. Some were leaner for smog or high altitude. If your center carburetor was changed for a non-tri-power carb then there is no telling what it wants. If you are running 56's in a real tri-power center carb, it is VERY lean. You should see light gray or white residue at the ends of the tail pipes.

.056 were in 2 barrel apps, that somewhere along the line, someone thought would make a good tri power center carb.

Old Man Taylor is correct on original tripower jet sizes, and they should work for most street apps. I have seen 70's in the ends and 65's in center for slightly modified cars

You can get jets for your Tri-Power from Indian Adventures. The 2bbl Rochester carb jets have a tapered seat. The Rochester Q-Jet has jets with a flat seat. You can use the Q-Jet jets in the Tri-Power carbs, just snug them down. You can't use the tapered seat 2bbl jets in the Q-Jet. http://www.chiefmanyhorses.com
