I have a 403 in my 79 TA that I am rebuilding. I am new to olds engines and pretty unfamiliar with what parts can be used from other motors. Will the oil fill tube from say a 350 olds fit my 403? I have had no luck finding a replacement fill tube for my 403, but see plenty for the olds 350 etc. Thanks

 

As far as I know an oil fill tube from any Olds engine should fit your 403 fine.

 

I appreciate your info!
