Are you racing in a particular class? as you will find most CAMS events require the original type of block and same number of cams/valves for eligibility..

That said if your doing AMSAG go a BA Turbo conversion :p

EB motor with AU internals..Esp if N/A ...
E.B head with AU valves and cam gear..Is an option with larger ports, lighter valves from A.U .. The AU valve guides will need to be fitted..Which should be replaced anyway..
I guess you can't get away with latter model manifold ??
Raise compression to around 10 to 1..
Lighten pistons and balance assembly..
Windage tray in sump with crank scrapers to keep oil off crank and oil in sump...
An MSD A6L2 or similar ignition box...If legal ??

Depends what class you want to do... not all rally classes have a 'free for all' on what you do with the car. Check regulations first

They have just started a new class where you can put a late model motor into a older car say for instance an sr20 into a 180b
