Re: hard starting with new Edelbrock when warm

The 600CFM is marginal for my small block 400 but might work ok on a bigger motor with larger jets. A stock '73 454 is pretty low compression and probably doesn't have much in the way of high flow heads, so you might not get much benefit out of anything larger.
