Makes it a 350. 330's and 350's were the same small block with different bore. 330's will take a 0.060" overbore safely and can usually be bored to accept 0.060" over 350 pistons (for a total 0.120-0.125" overbore) if desired. It is safer to stick to a 0.060" overbore, to allow fitment of standard bore 350 pistons, however.
The rule of thumb when it calls for overbores is 5 CI per .030 bore in a small block and 6 CI on 400 CI and above
A 427 bored .60 over is 438.8572417 or basically a 439.
330% of 60 dollars = 60*330/100 = 198 330% of 60 dollars = 60*330/100 = 198 330% of 60 dollars = 60*330/100 = 198 330% of 60 dollars = 60*330/100 = 198

60 out of 330 = 60/330 = 2/11
It is a 351c bored 60 over with 6 inch rods and a .4.0 stoke.
Sounds like a 343 to me. But for parts its a 283 bored 60 over

Olds never had an engine that displaced 442 cubic inches ( common mistake ) 442 was a model or option designation depending on year built engines available were 330/400/350/455/ Later on 307 General rule of thumb you gain about 2 cubic inches for every .10 over. Example 455 at .60 over would be about 467 to 468 cubic inch engine
a Chevy 350 bored .060 over would be 360.4 cubic inches
330 is 60% of 550. 330/550 * 100 = 60
283 bored .060 over should b abour 292 cubics A standard bore 283 was 3.875", so 60 over would be 3.935.
