May 650 Edelbrock carb has holes drilled in the primary butterflies from a previous cam install and now I want to repair them. What's the best way? Rivet, nut and bolt, or silver solder. Maybe epoxy? Of course the best way is just buy new ones but I can't find anyone that sells them. You...

Marathon opened a new gas station on the other side of town from me and they have a E0 pump. It's 90 octane and cost about $2.60 a gallon. Usually only find that stuff at marinas but was wondering is there any benefit running it in a car? I usually use Sunoco 93 octane and I have no spark...

I have a 340 based 373 ci motor that is mainly to be used for the street driving. I used several online calculators and based on a ve of .86% they all say I need a 556 cfm carb. Even at 100% it only at a 647 cfm. I'm leaning toward a 650 Edelbrock and was wondering if its big enough. I hear...
