New 1996 CCLB 3500 454. Help set my expectations on power or is there a problem

Yes, the test valve is post reg/inj, techically. The metal line it is in tees into the fuel rail halfway down and tees off at the regulator back into the return, so yes, you are technically post injection. Pump pressure is not the problem since it initially jumped to where its supposed to when the key was turned on. As soon as the pump shut off you started losing pressure, and from how slow it was I'd say bleeding injector(s) initially. Easy way to tell is pull the upper, hit the key, and look for leakage. If you look up at the pic I posted you'll notice the 8 smallest ports, thats where the injectors squirt into

And testing pre-regulator you would see much more pressure. Most stock pumps are rated up to 120PSI

Oh I see, thanks for the clarification. I saw many threads on which injectors to buy as replacements so I will read through those too. So I should look for a pressure regulator, injectors, cap and rotor, manifold gasket. Anything else?

 

[VorTecxas]

Be sure to specify plenum gasket, the manifold set only comes with the lower gaskets. And get a regulator for a 350, the one they list for a 454 is maxed at 50 PSI. Heres a current listing on eBay you should really jump on for injectors

Those are the same ones I'm running

So those injectors should be a direct fit? Should I worry at all that they are used even if it is just for a week and what would be a decent price to pay for them? Who makes a really good regulator? Sorry for all the questions but I really appreciate all of the help!

AND do not get the Duralast (AutoZone) cap and rotor. They are crap. I don't know where you go to get parts, but I suggest spending a little extra and getting at least the ACCEL cap and rotor. I had Duralast Gold cap and rotor on mine for less than a week and it misfired the whole time. Pulled it and it was carbon tracked like crazy

 

[VorTecxas]

Yes, they are direct fit. Hell, I'm running injectors that I pulled from a wrecked LS1 haha, so I wouldn't worry about those, it takes a lot to ruin a Bosch injector like that. I'm using a GP Sorensen regulator, part #800-315

This is the full gasket kit for the plenum right? http://www.amazon.com/ACDelco-12534...r=1996|1996&carId=003&n=15684181&s=automotive

 

[VorTecxas]

Yeah, but you wont need the lowers. I'd go ahead and do them, if it was me, but that requires pulling the dizzy and resetting it if you're up to that. It has to be set a certain way
