not sure where the best place to post this but anyways i have a 91 305 lb9..well i wanna ask about the redline on the car...i dont usually stomp on it too much but the other day i wanted to see what she can do from a dead stop and i slammed the pedal right to the floor and she reved waaayyy past redline and stayed there for too long then it switched gears and took off but i do know its bad for the motor to do that but dont know why it sits so long in that redline just seems like its barely accelerating????

 

Where the tires spinning a lot when it was revving up to the redline not going anywhere?


Or your converter might be slipping a lot or something. That's a really strange question to ask...

 

ive never seen a car sit so long past the redline like this....no i wasnt spinnin or anythin i started from a dead stop and slammed on the gas...the tach went way past the 7 grand i think it is and stayed there for like 5 er 6 seconds then it seemed to catch gear and go smooth from there...the past way to explain it i think is from 0-35mph the needle on the tach sits past 7 grand for a while and wont go anywhere then all the sudden its like a boom and it flies after that...???

 

Sounds like a slipping transmission.

I think you should re-post this question in the transmission forum. It has nothing to do with your motor.

 

Factory tach, My geaus is that the factory tach is WAY off if you are getting your reading from there.

 

i would HOPE he would be able to hear the engine revving along with the tach.

i doubt the tach is wrong if he is flooring it and the rpms go up and then the car shifts and takes off.

it is most definately a tranny problem
