Motor ID

He guys I'm little confused as to which motor is in my 1972 Plymouth Scamp. I looked at the fender tag and see that it has the E44 code on the bottom line all the way to the left which is for the 318 2bbl 230 hp. It also has the G2R code on the bottom line just before the sequential number which is for the 318 2bbl. 150 or 155 hp. Which one would you say is installed in this car? Thanks in advance!
