Seeking help assembling fuel system

[82firebird]

I am looking for help to complete our engine setup and fuel system. Other than the engine and supercharger, the car is a blank slate. I have no tank/lines/pump/regulator,etc. The engine as we purchased it is shown here:

•Stock 351W block, fully prepped and bored .040-inches over (360ci)
•Stock Ford 351W crankshaft, .010-inches under on mains/rods
•Ford rods, shot peened and ARP rod bolts installed
•Probe forged pistons w/ Perfect Circle rings, 8.9:1 compression
•Completely balanced (crank/rods/pistons/damper)
•Edelbrock Performer EFI 351W intake
•Accufab 75mm throttle body/EGR spacer
•42 lb/hr Ford Racing fuel injectors
•High-flow billet fuel rails with AN fuel line connections
•Edelbrock Performer cylinder heads
•Probe 1.6:1 full roller rockers
•Professional Products SFI rated balancer
•Elgin flat tappet camshaft (.496/.520 lift, 224/234 duration, 112 lobe center)
•Engine is machined for roller cam if a cam swap is desired
•Double roller adjustable timing chain and gear set
•Manley pushrods
•Pro Mustang 7-quart oil pan
•Melling high-volume pump with Probe Ind. HD drive shaft
•MSD EFI distributor and 8.5mm Super Conductor plug wires
•Complete Fel-Pro gasket set
•Edelbrock water pump
•Coast High Performance cast aluminum valve covers
•Paxton NOVI 2000 centrifugal supercharger with all brackets

The car was away at Gillis Performance and we just received at back home. I had them remove the upper intake when they dropped the engine in, because it was very close to hitting the hood. I didn’t want them to have to spend the time figuring the clearance out, so the upper intake was removed. I should know later this week (when I have the time) to see if the hood will clear the Edelbrock Performer intake. If not, what is my next best solution? Ditch the EFI and go carb with an enclosure or carb hat?

Should I choose my fuel delivery before planning the fuel system? I would like to use a nice tank, such as this: http://www.atomicfabrications.com/Item.aspx?ItemID=5015

How about fittings, line size, etc?

The engine dynoed at 515hp/541tq @5,000RPM. The car will be street driven only, never raced and never tracked. I want a well-mannered street machine that we can enjoy driving. I appreciate all of your insight!

I had a chance to set the intake on this morning and check for clearance. It is close, but will not clear the throttle body. The Eleanor hood has some good clearance, but just not enough.

The mid 90' EFI had an elbow between the intake and throttle body... Would something like this possibly help?

Is there room between the oil pan and cross member/ steering rack to lower the engine enough? If so, maybe you could rework the engine mounts or the frame stands(welded to frame). If that is a rod and custom front end, my understanding is their customer service is outstanding. You might want to touch base with them about a set of custom engine mounts.

Another option depending on how much clearance you need is to mill the lower intake down where the upper / lowers meet. Be sure to check for throttle body accelerator cable clearance to the valve cover if this is a doable option. I'm not sure how much you can go before it causes trouble, but I'm guessing 3/8" give or take would be possible.

I can't tell clearly from the pics, but before you take any clearance measurements , be sure that the transmission is installed as well since that determines where the engine will normally sit. It can sometimes make a difference on tight clearances.

Regarding the fuel system, wait until you figure out if you are sticking with EFI since it requires a return fuel line, whereas carb does not.

Thanks for the reply Stangg. I looked at the elbow you linked to. Tell me if I am figuring this correctly.. Change the lower intake to an EFI "carb style" and install the elbow on top, then the throttle body on the side? Something like this..

EDIT>> or can use that elbow to adapt the throttle body down to the side of the current intake?

This may give me the clearance necessary, I will spend some time looking up intake and elbow heights and go from there.

There is not much room between the oil pan and the rack, definitely no room to lower the mounts. I thought about lowering the rack mounting points on the cross-member, but I am not sure if that will change steering geometry.

The transmission is in also, it is a TKO600.

Thank you for your help!

Sorry, I was thinking that was the 94-95 style elbow.
This is the one I was thinking might work...

Would this manifold give a little more clearance?

Actually I just notice that you have an EGR spacer installed. If you are not going to run EGR, then you can probably remove that and possibly shift the throttle body closer to the manifold and maybe get the throttle body under the rise of the hood.

I run EGR on mine, but many don't. There is a way to trick the computer into thinking the EGR is present so that you don't get codes related to that.

If you choose to remove the egr and sick with efi, I have the little plugin that delete the egr and sends a signal to the computer. You can have it. I didn't end up using it.

I think you are going to have a hard time fitting that under the hood even with the taller rise. The 351 block has a higher deck height than the 302 that is in my car. I was lucky and the high point on the throttle body misses a hood cross brace by 1/2" to one side otherwise the stock hood would not clear. I have the engine dropped down against the new lower cross member. Some of the aftermarket EFI intakes, possibly yours, are taller than the 5.0 fox intakes. I can measure my stock cobra EFI intake and see if it gains you any height.

also, I can't tell from the picture, but make sure there is no spacer between the upper and lower. Lots of guys run them if they have the room for better performance.

Thanks for the replies guys.

Stangg, I looked at the Victor manifold and it is, unfortunately, even higher. I spoke with the Summit Tech Line who advised to try the throttle body elbow- so long as the intake clears by itself. I took the throttle body off last night and it's a no-go. The flange on the intake has a hair before the hood hits. I thought about milling the flange down, but even then, I don't know where that will get me once the elbow is on.

Thanks for the offer with the plugin Rabbit- I will see if we can work out the EFI setup and I may take you up on that!

Thanks for the offer to measure your stock Cobra EFI intake KB3. I would appreciate that! I double checked and there is no spacer between the upper and lower. I did think about milling down the top face of the lower, but the upper is already very tight to the valve cover on the driver's side.

The Summit tech advised that I might be best off buying a few options and seeing what works. Their store is 10 minutes from me, so that may be the way to go.

Didn't Dave Sanbourne have some clearance issues with his car. I think he ended up using a BBK intake.

Just shoot me a pm with your address if you want it and I'll send it out to you. It's Been sitting on my shelf in the garage for a couple years. It's just a small plug in about the size of a roll of quarters. Plugs right in to the egr harness.

Hey, if he doesn't want it, I'd be happy to take it off your hands! :thum

I looked up the BBK and could only find it for a 302.

I don't know how deep you want to get into manifold modifications, but here's an idea if you have access to machining / welding aluminum. Get the elbow and install the throttle body... if you're only dealing with clearance issues at the flange, then maybe consider milling the flange down completely and instead of bolting the elbow on, have someone tig weld it where you need it. I know it seems a bit extreme, but it looks like the flange is causing you trouble, not the runner itself.

Just another thought... if you elongate the three motor mount holes on the block side, would that allow you to effectively rotate the engine (counter clock wise ), this giving more clearance on the throttle body side, while taking some away from the plenum side.

I was going to suggest milling down the top of the intake itself to gain a bit of room. There is usually enough material there to allow some height reduction.
