Hi all whats the pros and cons of each?
Looking for 400ish bhp!
Have a bored out rail and 800cc sards but may sell them and go top feed rail with 1000cc! Lol!

From what I gather, top feed distribute the fuel more evenly than side feed.

You don't need to upgrade from bored out side feed to top feed for 400bhp.

Spend the money elsewhere.
