Hey guys, hows it going..

I have a 383 stroker (full solid roller, about 600 lift and 239 duration) in my 92 firebird. The carb is a holley 800 dp

The car was originally tbi, and i have yet to replace the fuel pump which recently died. What pump would you recommend? I have a holley blue but i only wanna do the swap once.. Should i use this one or buy something else?

Im going to take it to a shop because i dont feel like screwing with it. Guessing the stock fuel lines are fine?

thanks,
Shane

 

Don't try to draw fuel through a dead stock in-tank pump. It's restrictive. Either get a high-flow in-tank or take out the in-tank pump and go to a straight-through carb-style pickup.

Putting that aside, a Holley Blue along with a good fuel pressure regulator will keep up with that combo. Since your car has a stock return line already you should consider using it- with a return-style fuel pressure regulator (3 port) instead of a dead-head style regulator (2 port). Return-style FP regulator setups are easier on the fuel pump and hold more constant pressure without "pressure creep."

 

i am going to definitely get rid of the stock pump...

how much HP will the blue support? i want something good to at least 500 hp so i dont have to do this again.

i just wonder if buying a in take replacement would be better since i have to pull it out anyway.

 

Im going to be using a Holley Mechanical pump to power my 383. Part number HLY-12-327-13 at summit. i am pairing that with the MAA-4309 3-port return style.

i just prefer not having to drop the tank or anything if i ever need to replace the pump. I like having it tucked right up there in the engine bay.

 

i'm using a holley blue on my camaro right now with a mallory 3 port regulator. i have ran new 1/2 inch send and 3/8inch return lines along with having my gas tank sumped. if you don't want the holley blue you could also use a carter, or the aeromotive pumps are really nice but pricey at about $250+

 

Holley black "pro series"

 

well i already have the holley blue...

Do i need to rerun all the fule lines, or can the stock ones support ~ 500hp?

as far as electric vs mechanical.. i dont really care.. i just want whatever is gonna workout best for my application

i have to drop the tank regardless to pull the old one out

 

im really suprised at the lack of posts/replies .. this board has really slowed down in the last few years... what is happening to all the thirdgenners!

 

Your stock lines should fit the bill..as long as no power adders are in the future without a dedicated fuel system for it.But to feed the motor NA..they are fine.

 

They all hang at the Auto Detailing and Appearance forum...

 

lol.....one of the first funny comments i've heard from you in a while.

 

looks like im going to tow the car to the mechanic shop about a 1/4 mile from my house.... im gonna have them pull the stock fuel pump out and install the holley blue pump..


from there i should be in good shape!

thanks guys

(i dont have anyone to help me pull the pump, or i would attempt it myself).

 

I would never use a mechanical pump with any sort of high performance motor - no reason to starve the motor of fuel.

I would suggest a good electric pump near the fuel tank - sumping is optional and not necessary at 500hp, unless you want to use nitrous or supercharge it later.

 

Maybe try a magna flow pump. I think they have actually changed their name to magna fuel but whatever. Their expensive but well worth the investment. They will save you fuel starvation thats for sure.

 

For the street up to a certain limit mechanical pumps are fine, you will not be starving the motor of fuel.

To be safe though, an intank electric with a regulator is some safe insurance, but Ill doubt you need it with that NA 383.

 

Holley Blues power many pipe racks out there running isngle digits, we've got 3 blues and one black in our close group of racers, all work fine running mid 10's to mid 11's. I would personally stay away from BG pumps, heard lots of horror stories about these going south within a year and guys having to pay dang near full price to have them factory fixed. I'm going with the A2000 Aeromotive pump, wanna be different and a few guys running it seem to like to. Magna Flow is another great brand of fuel pump, but spendy. You can look at it as sure I'm paying a little more now for less headache later, or else skimp now and end up paying twice out of pocket and the hassle of redoing AGAIN!! I see too many people saving a buck today and spending it twice later, even some of my buddies that should be old enough to know better from experience-don't. Sumping is just a way to know the fuel is always going to be available when the hammer gets dropped.

 

i'll just use the holley blue.. i already have it, and itll be easy to change if i ever need to.

thanks guys
