I have a relatively stock 250. It has split headers and a Pertronix conversion kit in it also. My problem lately has been my one barrel carb. It's just giving me fits. It's a remanufactured Roch. BV carb and I've been through it twice (one rebuild & once tryting to fix this problem). I'm continually getting a backfire through the exhaust, jerking, leaking, and lack of performance. I can't figure out what the problem is.

I should have an Offy 4 barrel intake heading my way, and I already have a 600CFM Edelbrock carb sitting around. I also have the two barrel adaptor for the stock intake. My main question is, what do y'all think is the best option? I hate to buy another one barrel only to put a 4 barrel on later. The main concern with the Edelbrock is if it will work well with my application. I know I'd have to retune it, but I'm wondering if it would be worth it. Sorry for the long post, but I just don't know what to do. Thanks for any help. John.
