Good information. I bought an Edelbrock 7176 heated intake just in case and made a last minute decision to go with it. I could have saved it for my 340. Street manners seem much improved. I did put the 750 Holley back on it though so I could still change to my 650 Holley later. Or it seems like some people like the AVS2 carb. That may be even better. Thanks.
