Accelerator cable was the cause???
after getting my engine replaced (TWICE!) i went from the 180Hp to the 290HP, including edelbrock intake, carb and full exaust (headers, flow master...)
For the longest time My car was wayyyy slower then with my stock engine, no snap no quick response just slow and annoying. many told me it was a timing and carb setting issue.
a few days ago My accelerator cable broke. I got a new one and replaced it. Today weather was better so I took thew vette for a ride....IT WORKS GREAT!!! i feel like I gain 100HP (j/k) but seriously it's snappy it respond great it goes up in rpms ina blast from 2000 to 4000 it feels like a total different car. Could an old and maybe loosened by the years accelerator cable really be the cause for all this??

)See if you notice any difference.
A bad or misadjusted cable could certainly have been the cause of poor performance and response.

Make sure your new cable is pulling the carb all the way open. With the engine off, have someone mash the pedal to the floor, then make sure the carb is at wide open by trying to move the throttle manually in the open direction.

yes that was the problem. When press lightly on the pedal my car runs like it use to when I was full throttle. Now full throttle is...SOMETHNG ELSE!! It's hard to imaging that after spending so much money on my car what was making it run like crap was a simple acc. cable!!

I can just see us all running out to our cars to see if maybe there's another quarter throttle to be had!

You would be suprised how many don't have any idea if their carbs are getting full throttle because the cable was not adjusted. The guy who owns a dyno near me says that is one of the first things he checks when the customer looks a little disappointed with their HP numbers. He says some guys spend 5-10 grand on a motor and drive it around for a year or two with the throttle only at 3/4 full

Thats' one of the first things a tech should have checked when replacing the motor! You want to make sure the carb is opening all the way.
