93 Blazer Acceleration issue

[ilxciteu]

I have a 93 full size blazer with a 350. When you press the accelerator to the floor the engine revs to 3000 RPMS but the speed is a no go. If I'm lucky I can get 0-20 in the quarter mile. If I am traveling at t regular speed down the road and stomp on the accelerator same senario RPMs rev to 3000 but no acceleration. Plugs and wires have been changed and no improvement. Any suggestions on where to look next.

Is the tranny slipping or just no power from the engine?

No slipping with the tranny, just no power from the engine. After you drive a while and the engine warms the acceleration gets a little better but not what it should be.
