Re: Bad mileage, high rpm, high idle?
They had 350s w/454 an option.
Turbo400=electric kickdown/Turbo350=cable kickdown.
Could it have shorter tires causing the speedo to show a higher speed than actuall?Or...it could have the wrong speedo derive for that transmission.It woud have come with a TH400.So,if it`s got a 350 it could be from a 1/2t with 3.42s or even a 10-bolt 2.73,or whatever that super tall ratio they used.
I personally don`t feel any love for Edelbrock carbs.Is your`s a Q-jet replacement,as in spread bore?The Q-jet with smaller primaries,when set up properly,will yield far better econmy that a square bore.At least that`s been my experience.For years Q-jets have been toss for Holleys and now Eldys.It seems many are out search for the Q-jets to go back on,since GM got it right as they seem to do so well.
