Go to this forum and register at the 1988-1998 Chevy Forum. There are some real good technicians there, and the service is free:

But low power like that could also be caused by
improper valve adjustment or valve timing relating to one of more of the pistons. I would look carefully at the alignment of all the timing marks, and with the rotor pointing in the direction of piston#1 on the distributor, I would pull the spark plug from piston #1 and with a flashlight make sure that this piston is all the way up. If he can't see the piston because there is no room to get his head nearby, just take a clean wooden dowel, insert it into the motor through the spark plug hole, and feel the piston with it. If the piston is on top, he should be able to tell when the dowel makes contact with it.
The idea is to set the timing marks properly, and then follow the pistons firing order. If #1 is supposed to be at TDC, then this piston will be on top of the block, right below the spark plug and valves. If everything is OK, then check the valves adjustment.
