What size carburetor should I use??
Hey guys, I am having a difficult time trying to decide what size cfm carburetor I should install on my 1990 chevy small block 350. The carb I have on there right now is to small(backfiring through the carb, all that good stuff), so I'm looking to buy a larger one, but I dont know what size to go with. First off the cam is a Edelbrock 7102, ( Duration (in degrees): 308/318, lift: 0.325/0.340 (int/exh)). It also has a Edelbrock performer intake and headers to a 2.5 in dual exhaust. Last it has a 4 speed so I usually shift at higher rpm's than a normal automatic. This car is for street use. I was thinking a 750 cfm's but was reading and most people were saying 650 is better. Let me know what you guys think. Thanks, Dustin.
