a good set of heads and the right other stuff is more cost effective than the 174,and can create more power, IMO. I think merc only rated that motor at 490 hp overall, ,adding the intercooler didn't seem to do anything for the hp.The bigger 250 is a different story.

Don't mean to pick on you but this is also completely false.. There is no better bang for your buck then a blower. The heads, cam, valve train, and intake you would need to make 600hp with a 454 will cost considerably more then a 174 blower. If you're starting with an engine with too much compression then it might not be worth going the blower route.
I'd take the mild build motor with the blower on top.

These small blowers work very well in marine engines with relatively high compression. I know because thats my combo. 9.5:1 compression 468cids with 177 blowers. The higher compression crutches up the small blowers and makes good power with low boost. Pushs my panther to the low to mid 90s which is really doing something. I do run aluminum heads which is key.

This is true, the last motor I built was a 496 stroker motor that mad a hair over 600...it did not last long. AFR heads, 10 :1 compression, custom cam with over .650 lift, can't remember exact duration but a 108 degree center line and had to spin it close to 6000 rpm to get to the power....It had a short life unfortunately...

I never dynoed them but a good guess would be 650hp. The aluminum prevents detonation which in blower applications quickly causes holed pistons. This is as baja said due to the fact alum is a good conductor of heat. You'd need to be at least .5pt lower in compression with iron and that still might be pushing it a bit.
