Title: Upright headers question
Post by: blittle913 on April 09, 2012, 10:31:31 PM
I have a 30 over 460. Pretty basic, nothing special. Edlebrock performer intake with a 750 Carb. Not sure on cam but I think I was told it has a mild grind, maybe RV but like I said not sure. Anyway, I'm worried about not enough back pressure with uprights. How do I know what to run to keep power and keep my motor safe?

I think your motor is big enough for that size pipe and collector, any header with a collector will get u enough back pressure
