I am brand new to this site and looking for input on a engine I will be building some time this winter. First what the engine is for: I am currently building a 1986 monte carlo Luxury I believe into a dirt figure 8 racer. Currently has a 305 and a 200r4 that I plan to replace with a 350 engine and trans. The class I plan to race in is the stock class, meaning "stock engine" (kinda). The rules state must use stock exhaust manifolds. All ignition rotors, caps, coils and modules must remain OEM-appearing. Must have unaltered OEM factory intake, No aluminum intakes. Unaltered 2 barrel stock OEM carburetor for that engine only. Must remove carburetor choke plate. No carburetor spacers allowed. One 1/4" maximum thickness gasket only. Adaptor allowed from a 4 barrel intake to a 2 barrel carburetor. All engine components must be steel. No after market engine components. No porting, polishing or alterations of any kind to heads or intake. Engine must be OEM appearing and must be able to be used in conventional passenger car without alteration. Maximum engine compression allowed is 8.6:1. Must be able to carry 16 inches of vacuum @ 1000 RPM. No double hump heads. No solid cams. I realize this is a lot of information. And these rules say alot but it is what they don't say that I am interested in. I plan to use a rochster carb with an adaptor plate and a four barrel iron intake. Looking for suggestions on what to use for a good set of heads that will flow well made of iron, and what kind of a cam to use. The tracks I will be running on are mostly less than a 1/4 mile and I will need to be able to get on and off the throttle alot so need all the bottom end power I can get. I like to run my engine about 3500-4500 rpm or so and will be installing a gear ratio of 3.42 or so absolutley no lower than a 3.50 per the rules. The tech inspector will do a compression pump of the engine and a vaccum check of the cam. Any info will be given max concideration and greatly appreciated. Worst of all I am working on a budget and that never helps. Thanks.
