1969 440 4bbl, how good a motor?

It had a forged crank, no HP on the pad. Did have 906 heads, no exhaust manifolds. Had the oil pan that is good for swapping big blocks in A-bodies rather than the one with the baffles (its too late for me to remember the numbers)

Carb was from a 69 340.

I passed on it.

Thanks for the help guys
