I cleaned up the engine since you guys gave me a hard time for not cleaning the 454 when I had it out. How am I doing so far? Laughing

Last night I got those parts on and I got the shifter linkage fit. Just drilled a hole in the middle of the 700R4 bracket and it lined right up with the bolt on the TH400. Seems to shift fine! So now I need some rubber line for the fuel, some barbed fittings for the regulator, fit the lower radiator hose, and wire the alternator, distributor, and sensors. Shouldn't take that long, right?

Well, if you dont have cash flow it takes a long time to get the parts. But all the time in the world to work on it.

Once you get cash flow, you got no time.

I wanna see some vids of it running as well! How high does the front sit with the extra weight?

It only dropped the front another 1/4". No biggie. I'm hoping that my since my suspension was too stiff for a V6 that now it will be just right.

I'm doing far less than he doing though. It ran fine when I took it out of the donor truck! I think that if anyone has some stock exhaust manifolds laying around I'd use them instead of what I have.

i got all the fuel stuff on last night, kinda stoked! I even have a fuel pressure gauge (a cheap Spekter, but oh well), my upper rad hose is routed and almost done. Just need the bottom rad hose, figure out the exhaust, and wiring!

Sweeeet! I want to see a BB thirdgen drifting!

I got the heater core hoses on, spark plugs in, tranny cooler on, and was monkey'in with the fuel regulator. Does anyone else have one of these? It's a HOLLEY UNIT and I followed the instructions (figure 2a). I do not understand how this unit works at all. How can the out be an in??? I just don't get and it doesn't seem to be building up enough pressure but that could be the seats of my quadrajet not holding up.

I have that exact same unit on the Merc.

The bottom port is in from the pump, and you have two outs: one on either side. You can run dual lines to a carb that's setup for it, you can run a gauge and a single line as I did in the pic, or just block it off with an NPT plug.

I'm running an in-tank pump and need the return since I'm high pressure. Think my pump/setup is the problem?

I don't think doing a returnless vane pump is going to work. I ran it like Holley said and put the feed into the out of the regulator. Doesn't make sense to me. You seem to have ran it the way I think it should work, not how I need to do it.

aaron_sK · Posted: Mon Mar 09, 2009 11:43 am Post subject:

Ah, I had assumed you had a mechanical pump. They do show two different part numbers: a 12-802-1 standard and a 12-803-BP bypass. You might have gotten the wrong one with your kit.

Dang it. I've already run fuel through it!

How much pressure should a Holley or Quadrajet get? Can't you adjust them to take anything?

I'm guessing here, but I'd say 7 -8 psi max. Should be around 5 - 6 psi

Twilightoptics · Posted: Mon Mar 09, 2009 3:22 pm Post subject:

Think about how a carb works... the only thing that shuts off the fuel is the float.... like a toilet. Overpower the pull on the float and arm with pressure and the needle doesn't seal then you get fuel overflowing the bowls.

PSI should be 3-6 roughly. Holley and Q-Jet aren't as tempermental as say a Weber. 1 PSI on a Weber and you're roached.

what he said

4-5 supposedly is the sweet spot on a quadrajet. 6-7 on a holley.

this carburetor thing is a new but temporary fuel solution for me so I'm learning as I go. Once I get some 30# fuel injectors I'm stuffing them in! Till then I really appreciate the help.

I got the radiator lines ran last night! I also got the fan back in but I didn't snap a pic. So the few remaining things are the exhaust, alt, and distributor! Go me!
