hey guys what do you think adding a set of AFR 180cc intake ports, 56cc chambers, matched with a comp cam xtreme energy 290hr-12 hydro roller cam, .510 lift/.540 and a duration of 290/307 degress to an lt1? what kind of hp could i expect, and would i be better just building a mild 383 carbed? Car will mostly be track, but will also drive it around most weekends. I'm just trying to figure the best way to spend the little money i have.

I also plan on changing injectors to.

 

Thats a lot of duration for a FI motor. Going to take a lot of tuning.
