need new carburator
 

Sorry if this is not posted in the proper forum. I am looking to get a new carburator and wondering if anyone could give me some input. I have a 402 with a Holley carb of which my mechanic says is causing issues with the vehicle. It's failry old I believe and don't know much history behind it bu the car runs great for a bit and then just starts to die. Suggests putting in a Edelbrock Carb. Any suggestions? I'm a newbie to this so forgive me up front.
