Change your fuel pump

 

should be a tach filter in the line. it could be messing up the rpms on your tach. so when u get to a certain speed it acts like it hits a wall and wont go any more rpms? or do the rpms still go higher just not at a proper rate?

 

Like a tach with a rev-limiter? The tach speed wouldn't have any bearing on limiting the engine. The one on my 91 would peg around at highway speeds and it never cut the engine out. I already had that same thought too, until I re-thunk it!

 

69, i think there is a tach filter in the system between the coil and the tach, i was thinking maybe that is screwing with the tach readings. i was also trying to get a little better description of the op s issue. sorry if i got the two mixed.

 

so i am stuck at finding what kind of rear end i have and how do i find out if its stock or otherwise same with tranny ? how do i know?

Changing the spark plugs this weekend (I think) Havent did that either since ive owned it but i am pretty sure i have low gears i have this gut feeling i am gonna have to fix the rear end
