Default Need ID Help on Gen V 454 Crate Engine

What I want to know is the horsepower this engine came with.

Gen Motors Chevy crate engine

Here are the numbers and what I already know.

# on the front engine pad TO423XXA =
Tonawanda April 23 Crate Motor

On engine D133 = April 13th 1993

Block casting # 10114182 = 454 1991-up 4 bolt main GEN V

What I can't find:

Looks like suffix code on engine is CFD but I can not find the listing
giving this info for crate engines anywhere on the internet.

I would be very thankful for any help.

IIRC back then they had a rating of 230 HP for the base truck engine, and the 454 HO's were 425 HP..........does it have the oval or square port heads ? From what I have read recently, there were only 3 choices at that time, and the other one was a marine engine. Sorry I can't help any more than that.

Has rectangle port

open chamber

118 cc chamber

I am sure it is either 454/425 or 454/502 but I can't nail it down.

Not sure if this helps, but the XA 454s were used in marine installations, 365hp, rectangle port, steel crank.
