What kind of hp can i expect with a fresh streetported 13b and a weber 48mm dcoe carb / headers ?

 

4 port or 6 port?

 

A 4 port should make about 185 HP. Not sure about a 6 port.

 

All depends on the rebuild, parts used, ports, exhaust, tuning, etc.

Results can range from 170 to 220+ at the crank.

 

Well, supposedly my 6 port made 150 RWHP according to the last owner of the engine. This was with stock induction and 3 inch exhaust. I'm pretty sure it will make 180 when I convert to carb and put a proper exhaust on it.

 

Mine put down 124rwhp on a dyno with stock ports, RB header and blown out cat. Doing the math that is around 140-150 to the flywheel. I am sure that a 6port can easily do 180 with the mods that you have planned.

Are you looking for crank hp or rwhp?

 

Mine Is A 6 Port / I Have Already Done All The Work But Have Not Gotten
It Completely Installed Yet. I Am Waiting For Some Rb Injector Plugs And Main Jets For My Carb. I Also Used A Rb Exhaust Template And Ported The Exhaust. I Can't Wait To Get My Parts So I Can Start It Up
