engine code(pic)
 

all I could find out was it was made in the Tonawanda plant in 69 and it had 300hp. Is there anymore info that can be got from this number?

IN 1969 350 tur 350, taxi - 2 full size

looks like it might have been a 2 barrel with an automatic and came in a fullsize car if i read that right and the last 2 letters are IN
