hey guys i'm looking to buy a 48 weber dcoe for my 7... i currently have a 45 on my stock 6 port.... willing to trade my 45 if anybody is interested... thank you guys in advance

 

Wrong section, also, why do you want to go to a 48?

 

oh sorry bout that... but yea i was reading up on the past threads that upgrading to a 48 is better for a 13b motor...that the 45 is too small for a 13b... any advice

 

I have my doubts about that. A 45 DCOE flows around 420 CFM with 36mm chokes. You'd have to have a very impressive VE for it to become a restriction even at 8500 RPM. Stock or streetported with an 8000 RPM limit, you're not ever going to need more than what a 45 DCOE will provide with the "recommended" 36mm chokes.
