cam and lifter questions

[SRVBLUES64]

Ive been having issues with my enigne not running good almost like someone pulled 4 wires off I cant figure it out I've been through the basic timing and carb tuning So I pulled the engine I know drastic but I had to or I just wanted to look busy. Im not sure if I installed a solid cam or a hyd cam I know I have hdy lifters. Will that make a big difference? should go with buying a cam that I know is a hyd cam? any suggestions

First off did you buy this cam as a kit, cam and lifters, yea pulling the engine was a little extreme, you should have pulled plugs one at a time and look at color first, black being rich, ash white to a hazy silver being way to lean, are they new plug wires, dizzy worn out, is this a new build, was the cam break in done correct, we need a little more info here....

older engine, new cam, lifters not a kit, new dizzy, used performer manifold, new oil pump, new gas pump, new wires, water pump new, new headers. new holley 670 avenger, new gas filter, I was having issues with seconadries nor working check vac at 14 not sure what gas is being pump in, new tank, plugs are black, timing chain was set right on. secondaires werenot coming on when then did they bogged down it was idling great even in gear but then one day it just ran bad would barely idle, My father inlaw said it has to be the cam so I went nuts, damn

How does everything look as far as wear?

Since you have her apart you can go ahead and get a cam and lifter kit if it's in your budget.
Is it small block Chevy?

I looked at everything, and there is no wear on the cam or lifters ,

Sounds like a carb problem, at least figure out if its flooding or why its running rich. And put in a new set of plugs. I dont know the details on your engine but im guessing its pretty much stock? In most cases on a stock engine you should probably never "feel" the secondaries come in. If you do and you have a vacuum secondary Holley then you need to change the secondary spring to a stiffer one.

before I tore the engine apart the truck sounded and ran ok then one day it just went down hill it would idle I could'nt get it timed nothing would help. the only real issu was not kicking in when i stepped on it it would just bogg down. I did try the stiffer spring but to no avail I installed a gas gauge but it ran so bad it didnt matter. so I got impatient and took her out only to find out the engines ok spark plugs were black oil was black and new too? I even took the carb spacer out to see oh well shes going back in on wednesday

I'd recommend doing a compression test if you haven't already. Also what year /type of engine is it?

[SRVBLUES64]

no I did not do a compression test, the block is a 350 year 74/85

Just a thought but I have been caught before by simular simptoms, tried carburator, distributor and timing ect., Ended up being a power brake booster gone bad creating a major vacum leak. If you have power brakes check your booster and make sure it holds vacum. May not be your issue, just sounds simular to the one I was into, ran good one day and the next day no good.
