[G.A.S.]

I have no idea where it came from. This rebuild came to me as adjusting the ticking lifters. Found a bent push rod and when removed, the top of the lifter popped out of its shell so off the intake had to come.
The rest is history.
When I looked this engines #'s up it showed ( police ) . No HP rating and 2 or 4 bolt main, 2 or 4 barrel carb. Lotsa blanks across the page. Must not have wanted anyone to see what they had back when. It does reference a 1969 - 1974 for the block.
the kid I am being so nice doing this for is full of questions that I care less about but thought I would offer him some insight. Hence posting here.
I just wanted to tell him how many hp it took for each item as he is looking to gain HP by installing an electric fan. He has the fancy brushed aluminum fan with no clutch.
I do however appreate your input.
