Looking good. The wiring could use some work yet but I certainly understand the "good enough to get it going" approach.
I helped a friend relocate the fuse panel to the back of his Eagle Talon. All the "extensions" are the same color. The running gag now is that any electrical gremlin must have something to do with the green wire.
What sort of air cleaner do you have to run to clear the hood?

As Nathon mentioned, it's going to be tough getting that under the hood with an air cleaner.

Please don't think I meant any offense by the comments, I didn't.
BTW if you haven't heard that hooker header / flowmaster combination, you're gonna love it.

I would really look into running a line from the regulator back to the tank not sure that stock pump is going to like being deadheaded like that. Longevity thing.
Good on you for getting rid of that firehazard the PO called a fuel line sheesh. Scary repairs being done out there.

Yeah I noticed there is a lot of other stuff missing. There really isn't anything wrong with a good enough to get it going approach, in fact sometimes it can be helpful. Nothing sucks worse than having to tear back into your pristine wiring because of some small detail or thing that was overlooked.

and yes I love the way it sounds. The car ran perfect before I ripped the TPI off if it.

A car needs fuel and spark to run. Pull the air cleaner off. See if the accelerator pump squirts gas. If yes, check for spark while cranking. One of the above should be missing. If all works, your motor may be flooded. Check the float levels of the carb. When I carbed my 84, the underhood temps got so high the fuel would perculate and flood the motor.

Gonna go out on a limb and say it is not the fuel pump. If it was a volume problem you would have problems under load but it would idle. Sounds like you are having much the opposite problem. I am betting on a float level or a heat problem as others have mentioned.

There is no reason why the stock pump shouldn't be able to supply the carb with a proper regulator. I'm betting on too much fuel rather than too little. Incorrect jetting, incorrect float level, too rich an idle circuit, etc, etc. Lots of things you check before throwing a pump at it.

Did the carb swap a couple years back,with other mods very happy
you need a return reg around $100.00 i would ditch that air cleaner also,check float level and the needle and seat in the carb for hanging up flooding motor,that reg might not bring it down enough did you put a pressure gauge on it?try a 650 holley double pumper carb i posted some new pics in my corvette photos,close up of regulator setup,return line comes out the bottom i have it stainless braided with 6an fittings to the stock hard return line and to the stock fuel filter,the rubber hose is a fire waiting to happen so is the foam air cleaner,the weiand stealth intake will fit with a drop base air cleaner

Is all this stuff in your profile still underneath that carb setup now...
" Bow Tie Phase 3 heads,Comp 268 XFI Cam,Comp Mag 1.6 Rockers,Headers true duals,no cat. "
That ought to run pretty good. I have always wanted a set of those heads. I am interested in how those heads run. cant find much info about them online.

its probably been suggested , but disconnect the fuel line , try to start it with the fuel in the bowls, should run for a few minutes, if it does , your issue is probably to much fuel as suggested prev. if it wont run, your issue is spark , also suggested prev. carb setups are real simple, gas ,spark,air, also probably suggested earlier.

Yes same stuff, It ran great till my last fun time with a gto i hurt someting in the motor,has a rattle in front of the motor just above the timing cover?any ideas?i like the heads but i guess the aftermarket alum heads flow better unless ported,i may be going 406 or 383 depending on my problem,hope har balancer,or timing gear chain or cover issue?took left side valve cover off all good,going to look at the right side today,any suggestion would be helpful not wanting to do more than i have to.i need a younger back to bend over that car
Stretched timing chain?
I can't think what would be 'above' the timing cover that would rattle unless you have a collapsed lifter.
Even then, it would be a loud 'tick'.
Get a stethoscope and listen to the engine.
If you don't have one, use a piece of 5/8 hose.
Oh.. make sure you remove the serpentine belt first.
Wouldn't want any fingers to come up missing!
