Qjet 17057253 on a 380 Olds stroker

<< < (6/6)

Cliff Ruggles:
7041250 is an early Oldsmobile unit.  They used small MAB's with those, so leave them as-is.

I'm not overly fond of the Olds carbs thru 1974 for high performance work.  They still used the early float/hinge pin arrangement and don't like high fuel pressure, or larger N/S assemblies.

They can be difficult to keep full on hard runs.

The later carburetor (when working correctly) is superior in just about every area......Cliff
