Why won't he at least try? It'd take 5 minutes to know whether or not the thing's coming out. You'd be out some labor is the only downside.

He was poking around and said there's a screw on the rotor shaft that's hidden under the lip of the intake; I haven't had a chance to check for myself to see, but he's done more work on Vortec 454s than I ever have.

Also @Mangonesailor, we got the scanner hooked up to the truck but it took two attempts, one with his Snap-On Solus scanner, it only accepted to read the truck as a 2001 C3500HD with an 8.1, but his old brick scanner only read as an Express van with the 8.1
Does it matter which one we use to perform a relearn? I don't want to accidentally brick the computer or something goes haywire in the relearn process.
Haven't done much lately because the truck really doesn't need much; my mechanic said he didn't feel comfortable trying to replace the dizzy without pulling the intake.
Which if it does come down to it and he needs to open the intake up, I'll probably have some different injectors on stand by; anyone got any suggestions?
I do need to give the truck a complete fluid service, it's long past time for that I think.

I don't think it really matters, but i suppose just do it as an express van since that's what the truck thinks it is.
He's wrong on needing to pull the intake to swap dizzy's. I't s a 14mm bolt you have to loosen, then rotate and take the cap off. And it comes right on out of there. I think for it to slip behind the instake it has to be a little sidways, but it's easy. He just doesn't want to do it. I'm not aware of whatever hidden screw under the rotor he's talking about.
The distributor definitely comes out with the plenum on. I've done it.
As far as injectors go. Whatever mangone is running for 28s would be a good size. Anything 24-30 @3 bar would be good. Something from a gen 3 gm would be nice, makes the data easy.
Grand Prix GTP injectors FTW. 42# @ 4 bar and readily available at the junkyard.
I have a cam already, blower is what's in my future. The ASA LS1 came with those 42# injectors, so factory data exists for the GenIII LS PCM.
+2 for the gtp injectors, that's what i'm running.
Also maybe try fuel injector clinic? They clean then flow test used injectors - supposedly.
Mangone, my at idle fuel pressure always sits 48-52 psi, i also though this was very strange.. so i installed a pressure transducer on the rail and tied it into the egr sensor. Turns out fuel pressure under high map ends up being in the 58-60 psi area. Wondering if yours does the same.
