Friday I dropped my block off to start getting prepped. It is a 350 2 bolt with no provisions for the spider plate. I want to run a roller cam, and upgrade the heads. I think I may keep the stock intake just to keep cost reasonable. I'm looking to get around 300 crank horsepower from the build. Does anyone have recommendations for a good roller cam and head set up that would get me to my goal? I'm not totally against vortec heads, but I think there are probably better ways to go. Just FYI, I'm keeping the TBI setup and it's currently at SPR performance getting their complete overhaul and boring service.
