Dust off your crystal ball and GUESS the horsepower !

If we did, it would be fitted with a carburetor. I wouldn't go through the trouble of trying to make the EFI system work.
Correct. That's how I was talking about. If you could find one still in good shape and was a good runner, you could put a good intake and carburetor and headers with a good hot distributor with a loose curve and there's your 300HP. Problem is now, they are getting older and harder to find lower mileage examples.
