that is the link to my pull of the 3a, swap everything over and drop a 4a right in it's place.

bit off topic but can i get a lumpy cam for this 3ac engine and will i need to have better valve springs or will they be alrite and how much is it for a lumpy cam aus?

our valve springs floar around 7000 rpm no use for a good lumpy cam, you would need double valve springs or simply get higher rate springs

The 3AC cannot be bored out to the same size as the 4AC. Max recommended overbore doesn't even put you close. The difference is something like 3mm of bore, way more than you can do with a simple overbore. Maybe if you went so in-depth as to do a sleeving job.
