Tripower Center carb jets

[sloane]

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.

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
