Well, it appears that the problem was with the 750 Carter . I swapped it out with my 600 Edelbrock and it's running just great. I purchased the 750 cause I was told the 600 would not be enough for the 401. Where will I see a difference? It seemed to pull great off the line up to 70-80 when I backed off. I don't have any experience with an engine like this (304 was biggest I ever had before). Thanks. Marty __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
