hey guys, this is a lsx 443ci, drag purpose, 13.0:1 scr, ported ls7 heads, 54-502-11 mechanical, roller tappet cam, 250 hp nos shot, we're 5000 feet above sea level, what carb size should i try? and what primary and collector size for headers?

 

car is a light one 1350 kgs.

 

What kind of horsepower (estimate) are you making??

 

I would have pro systems spec and build a carb. A SV1 platform single barrel.

Headers, I would say a 2 inch primary and 4 inch collector

 

Dominator and 2" primary maybe stepped larger with 4" collectors

 

something around 650 hp
