Usual combo question
I'm using my car for street use more than anything and I want to hear some opinions about my setup.
XE 268 I .509 1.6rr 268 dur 114 LSA
E .512 1.6rr 280 dur
670 holley street avenger 70/74 jets with an edelbrock air gap dual plane
GM performance fastburn heads 2.00/1.55 with hedman longtubes
I still have the stock converter (haven't gotten to it yet)
Should I stick with the carb or go larger? I did the basic calculation and with the dual plane offset, it comes out to about 750. That seems kind of big to me. Also should I stick with the dual plane or go single? I wanted the dual for better low end when I started swapping. Any other suggestions would be great.
