A 283 is a short stroke, high reving low torque engine.
The same tricks people apply to a 350 won't build an engine to do what you want on a 283.
You say "The Most Power", well "Power" comes in at different RPMs on different size engines. With your 283 you want to keep all the power it makes at lower RPMs.
What's the casting #s on your intake? What cfm is your carb? Stockish 283s like around 500 cfm, not over 600.
In my lifetime I've had well over a hundred 283s, anything from stockers to full race engines in 3200 LB cars, but had to run a 4.88 rear axle. Heck I even sleeved a 302 down to 3 7/8" & made a 283 from it. They are really good engines.
If you need a manifold to fit the carb I think one of the old C3B Edelbrocks may be a good choice, I wouldn't use a single plane. I think I have an old Offy 360 around someplace, if I can find it you can have it.
I certainly appreciate the responses! Thanks! And I certainly wouldn't ever think that a 350 and a 283 would be built with similar components.

The dual plane Edelbrock Performer is a 2101, which I was thinking was comparable to the Offy 360, you mentioned. The cast iron 327 I have laying around is a 3783244. (62'-63' 327)

I believe the Edelbrock carb I have is a 1405/6 (600 cfm). I need to look at it again to make sure it's not a 1404 (500 cfm) carb. I'm concerned the 1405/6 might be too much.
