Putting a Hilborn 2 7/16 on my 383 SBC in my front engine dragster. Got the intake on and im waiting on some parts to finish it and now I need some help. Ill post the engine info below,If I leave anything out im sorry.

Any science on stack length? I bought new ones and they are roughly 13" tall.

For drag racing..some use a high speed and some dont. I launch the engine from 3600-4200 depending on the weather and shift it at 6500. Most people ive spoke with say no high speed till i get it lined out then add it on. Thoughts??

No idea on what to start out with for pill sizes in the main...I will/can buy a assortment but need to know where to start.

HELP!!!!!
