It's alive !

Idles like shit but mostly had it 1500-2000rpms. Probably a little under carved with a two barrel 287cfm motor craft / holley but its alive. How much cfm does a 4.7 need with a small port job. I'm leaning to a 500 FM Eddy. I hate holleys with a passion. I don't want a 470 avenger. Did I mention its alive :banana:

If maximum rpm is 5250rpm and displacement is 284ci, the carb size required will be around 430cfm so a 500cfm Eddy should work fine.

Thanks I figured. A new carter / edelbrock 500cfm are outrageous. Eventually I'll find one to glass bead blast a d rebuild
