So i posted a thread on what i should replace but now my question is where i could find valve train for the 330. any help would be appreciated. i have locked at the local auto parts stores but cant find all the pieces needed.

 

Are you going back to stock or ....? If your building a street motor post what your doing because I may follow down your path!!!!
Thanks in advance!!

 

oh ya i guess that would help lol
i have a 65 f85 olds with stock 330 and wanted to keep it stock. what do you have?

 

67 Cutlass holiday Coupe -330 high compression - I was thinking on rebuilding beyond stock though!

 

oh really? on another thread a guy said that a lot of 330 and 350 parts are interchangeable, but don't quote me on this. i really want to know if that is true. i would really like to know if that is true

 

does anyone know if 330 and 350 parts are interchangable?

 

This might help a bit. I'm in the process of contemplating what to do with my '65 330 and found this link.... https://classicoldsmobile.com/forums...ine-build.html

 

I have a 330 too, going o be building it up a bit.

Valves are different sizes starting in 73, but just about everything with the exception of the exception of the manifold will swap from a 64-90 SBO and 68-76 BBO

 

so it is possible to use sb and bb parts on the 330 except for the intake? thats awsome. but if you change the heads to a sb from a 350 wouldn't you also be able to use the intake for it too?

 

The 330 and 350 are both small blocks. Everything that bolts onto the block will interchange. Even the crank shafts will interchange. Since the 330 all had forged cranks some people use the 330 crank in a 350, which came with cast iron cranks. If you have time you might go to the wiki site, use the following link: http://www.oldsmobilewiki.com/index....gory:Top_level This will give you a lot of information about the 330 and 350 engines, plus the big blocks if you want to compare the different options for your car.
