650 or 750 Edelbrock on 340

The roadrunner I spoke of earlier, I don't know how much cam he had, it had a noticeable idle to it. I don't know what the compression ratio was or what was done to the cylinder heads. All I remember is that it was a dog off the line and he lost a few times to sbc and sbf. Like I said earlier that I suggested that he get rid of his 1050 dominator and single plane intake. He did go to a holley 750 DP and a dual plane intake, I'm not sure but I think that he went with a Weiand. After he did the carb / intake swap I didn't see him again, I had heard that he had sold the car but I don't know this as a fact.
