100 horse shot of nos for 440?

What I was concerned with was approx horsepower Lord knows what it was stock but with the cam and intake and carb change and headers added maybe with the pocket ported heads it's making a little more it's a 77 Dodge 440 out of a motor home and has a set of 452 casting heads which have been reworked we raised compression alittle and also went with 020 steel shim head gaskets Are we still talking about around 300 HP that's why I was considering the 200 shot of nos doing all this work to build this motor and stuffing it in that car really wasn't worth the time if the horsepower is in the 300s
