Big Block Edelbrock limitations.

While I appreciate all the replies, I think some are going off the rails. I already mentioned that the converter isn't right. Nor did it have anything to do with the original question.
Also, anyone can see this isn't a full time race car. That isn't the original question either.
So, I simply wanted to know how much horsepower a set of stock rpm heads & intake can support/produce. I do realize that everything else contributes to horsepower,
That way I can think about what I would do on the bottom end. The engine is tired. I built it 20 years ago. It will need going through. So, if I have to go through the bottom end, I want to know where I stand powerwise on the heads/intake. The questions about stroke, bore, compression ratio, cam, etc. are for later.
The only one who gave any answer to the question id IQ52.
