ok yall.. im not going to tell the following.
jets installed, secondary spring installed, timing set at, and advance springs in distro.

Id like to see yalls input.. my current set up has me "flattening out" bad at 4 grand... which is weird.. i cant figure out why.... ( i keep tweaking but ive been so all over the place that i just need to start from the beginning)
I need to get a new timing tape on my dang balancer also..
SO! here's the list of things done ((yall have seen it before))

carb holley 670 carb with a 7.5 power valve. (8.5 is way to rich.. 6.5 causes serious delay)

Are you sure the secondaries are working? I had a motor very similar to that and it was very picky with the Timing. Had to run the lightest springs I could find. But if your losing power I'd try another Carb and see if it fixes the problem. I had a couple carbs where the secondaries wouldn't work and it would fall on its face around 4k

Get an Air/Fuel gage connected in and see what happens at 4k. It may not even be fuel related.
