E44 230hp 318 in 74?

So i type in my fender tag into one of those decoders..... http://www.mymopar.com/index.php?pid=87

It tells me 2 interesting things....

I have 1 of 70 code C15..... deluxe seatbelts lol
and the E44 which says it has a 230hp 318 2 barrel

G4B: 318 150HP(net) or 170HP(net) 1-2BBL 8 CYL
1974
Dodge Main, Hamtramck, MI, USA

35992: Sequence number

E44: 318 cid 2 barrel V8 230hp

Which hp is the correct?

Did a 230hp version exist in 74? Is this Flywheel hp? My Grandma owned this car and then me so I know the tag has never been tampered with.
