502 chevy bb with holley intake upgrades or procharger
 

I have 2 volvo 525 dpx motors built by innovation marine. They are basically 502 chevy big blocks with a holly fuel injection intake on them. I am looking to get around 700 hp out of them. Which would be the better way to do prochargers and if so how reliable or other upgrades such as heads, rotating assemble, cam etc. Any advice
They are in a 42 fountain

Thanks a lot

you are going to need boost and a go bit of it to get there...

Depends on what parts are in your motor now, and how much you want to spend.
