Did not consider that the oil pump runs off the dizzy any ideas?
[/quote] You can go external with the oil pump, and use a belt drive like most dry sump systems use. You also will need to consider how to route oiling to the head for the cam journals and other components that will require it. You might consider the newer 4.2 trailblazer engine/head for a comparison. It already shares a similar displacement to the 230 engine, and the valve sizes, port volumes and combustion chamber size and shape could save you a lot of guess work. They are dimensionally similar in length, and intake and exhaust manifolds could even be made to work if you pattern your design to use them, saving you additional designing and work developing those pieces. Try to utilize as many components that already exist from other engines.
