You need someone to help you this is to big for email, I have a bout 50 questions just on what you have posted. Get with a knowledable friend, and beg him/her to help.

Timing and valve adjustment seem suspect at this point, both with give you the problems you have discribed. A slow or improperly timed motor would have no power when first accelerated and would gain, rpm and power as it winds up.

A loose valve train would do the exact same thing, basically move your power to the top end while robbing your low end. I would get the valves adjusted asap, go to Comp cams web site and read there adjustment procedures, even print it off and follow the instructions carefully. I adjust mine while idling, but I'm kind a old school. I back them off until they rattle and then tighten 1/2 turn. But like I said I'm old school.. Check your oil after you have finished. Ear plugs help if your hard of hearing like me ! EeeH? What ya say?

The timing would come next, put in some light springs in the distrbutor and see if that helps. I would do this after comfirming the TDC and timing are correct first. Hopefully you installed the timing mark correctly when installing the cam. You should run about 10 degrees btdc maybe even 12-14 degrees with atotal of around 28-34 degrees depending on a multitude of factors.

Adjust only one thing at a time until you have verified each as right, in other words don't adjust everything and take if for a drive. One thing then drive, then adjust something else. Sounds like you have many gremlins to work through, but this is how we learn I'm sure you will prevail, I have faith. Mac
