Most of the 300's of the 1960's with a stock 4bbl carb ran 300hp rating. The Fairlanes GT's in 66 and 67 had 335hp. the 1960's 390's with 2bbls ran about 290hp.
The D4 number you give would be in for a 1974. I'm not should of HP ratings on the later engines

In stock form a lowly 195hp (net)
By the 70's the 390 was a mere shadow of its former self, suffering from low compression, low lift cam and smog era junk.
The 60's 390's (4bbl) were typically in the 300-335hp range with a few notable exceptions.

I was told it was rebuilt at a local speed shop, so if i did a compression test, and got numbers in each cylinder of 180 psi, would it be safe to assume its not a stock 74 spec motor?

140 psi~8:1
150 psi~8.5:1
160 psi~9:1
170 psi~9.5:1
180 psi~10:1
190 psi~10.5:1
200 psi~11:1
If the motor was rebuilt to stock specs you'd see around 140 psi +/-
