I really can't remember much about when I did mine but it made way more power than that.
Rammers work very differently to a springer. Much quicker lock time due to the higher pressure.
One of the issues is maybe the spring itself.
I'd have fitted a Titan or other stiff thick spring for sure in mine and very likely used the hw35 or 80 sized "export type" spring, as they were both springs of choice for me in the early to mid 90's. It may well have been an OX i fitted.
Another valid point may be the "oversprung " thing. When I did mine I did it alone without a spring compressor. I've never owned a spring compressor so it wouldn't have been that hard.
