Yes. 403 is a small block with identical exhaust ports as a 350 and 330.
Check the diameter and circumference of the flywheel for each transmission. IF they match, then the flywheel will fit.
Chevy, Buick and Cadillac shared the same bolt pattern as did Oldsmobile and Pontiac but, some transmissions had two bolt patterns to fit all GM blocks. If your Chevy Turbo 350 transmission has the dual pattern it will fit the Oldsmobile engine, if not it won't fit.
not if it is an Oldsmobile engine, Buick, Pontiac, and olds had the same bolt pattern in the 70's, different from Chevy
Not likely why not just use the correct part?
