Hi Norman. I had a '68 LeMans w/the 215 hp Sprint engine. Actually ran pretty good for only 250 cid.
Pontiac OHC Q-jet carb numbers:
1969- 7029260(AT), 7029261(MT)
1968- 7028260(AT), 7028261(MT), 17054906(?typo prolly?)
1967 (230cid) - 7027268(late, AT w/o AIR), 7027269(late, MT w/o AIR), 7037268(late, AT w/AIR), 7037269(late, MT w/AIR)
The following is from
High Performance Pontiac:
7027260 (early, AT w/o AIR), 7027261 (early, MT w/o AIR); 7037260 (early, AT w/AIR; 7037261 (early, MT, w/AIR)
1966- 7026260 (AT), 7026261 (MT)
Before going further, are you actually working with a Pontiac Sprint or Sprint clone, or are you tuning a different but similar set up?
