[/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. [/quote]
With the Trailblazer 4.2L are you talking about 4.2L Vortec? I believe those already have 4 valves per cylinder and make about 290 hp?
I would love to see one of those heads. However, I can not find much info on them, or even a picture of one off of the car... It would be pretty hilarious if they shared the same bolt pattern.
as for things like intake, exhaust, and other misc components I plan on making most things that will not be insane. My shop has an abundance of aluminium sheet metal for an intake(plus that way I can do all that fun number crunching and come up with optimal runner length, shape, and of course some Computer Aided Engineering fluid dynamics) Exhaust can be made by piecing sections of stainless mandrel bent tubing.
If anyone knows where I can find info on the chevy 230 blocks(actual schematics and such) or, more info on the 4.2L votec?
