Trick Flow Upper End Questions

[FFRSpec72]

1. What plugs are recomended, I was using Autolite 25 before ?
2. Can normal ARP 154-3601 head bolts be used ?
3. I assume that FelPro 1101 head gaskets or Ford Racing M-6051-A302 can be used?
4. Will the current cold air tube work (stock) or are we expected to modify?
5. Are the torque specs for heads, intake, etc same as stock?

[ED@TFS]

These are all great questions I will start at the top and work my may down.

1) Autolite 3924 is what we do all our dyno testing with. For you application this should be a perfect plug.

2) ARP 154-3601 is the correct head bolt. We normally torque them in the standard bolt sequence starting with 35 lbs – then move up to 50 lbs. Then on the last pass we will go up to 70 lbs on the short bolts by the exhaust manifolds and 80 lbs on the long bolts under the valve covers.

3) Head gaskets we use the Fel-Pro 1011-2. I don’t see any reason why the Ford Racing gasket wouldn’t work fine.

4) After assembling the top end kit everything will be in the stock location as far as bolt-on. The cold air kit should work fine with no modifying.

5) Intake manifold will be 22 ft-lbs. Make sure when you install the intake manifold you go through the sequence about 5 times. The SBF intake manifold pulls straight down so it takes a few turns to get all the bolts to hold at 22 lbs.

Anything else please ask,

Thanks again

Hi Eddi, are headbolts and headgaskets included?

[FFRSpec72]

My understanding is yes, I was asking as I have a spare shortblock and wanted to know what to use when I need to swap lower end

[ED@TFS]

Yes, all are included with the kit. The only thing you might need are intake manifold bolts if you dont want to run your currect ones.

Thanks

Some addtional questions:

1. Is the stock fuel regulator (not variable) sufficient, that is will the stock 38-40psi be enough for the 24lb injectors?
2. Is EGR eliminator required/desired?

[Jim Schenck]

I would be really careful running the stock regulator just to make sure you aren't lean on the top end. It would be much better to have the adjustable one, but if you don't I would run the car on the dyno with a wide band O2 just to make sure everything is OK before driving it on the track.

The EGR eliminator is not required but since the stock EGR is so restrictive it is definately advised. You do not have to use the one we give, the rule allows for any plate up to 5/16" thick, but the aftermarket EGR spacers are not legal.

[FFRSpec72]

Any suggstions on a variable fuel regulator? I assume that the Kirban 5005 is ok, since it is not that expensive? What is the fuel pressure that the test mule was running? I assume somewhere around 40-45?

[FFSpecRacer]

That looks like it would be fine. A lot of us run the Aeromotive 13103. I've even seen one from Holley.

I'm sure Jim will chime in the fuel pressure as I do not remember. I'm sure it is in the 38 to 44 range.

[Jim Schenck]

I ended up in the mid forties to get between 12 and 12.5 A/F which I considered fairly safe. I also ended up at 16 degrees of timing which is a little more than the iron heads seemed to like.

For a fuel pressure regulator Aeromotive is good as are most of the others, what I look for is a wide range of adjustment, including being able to go lower than the stock 38psi as sometimes that is what works best. I also like the one that will take a fuel pressure gauge and not use the test port.

[ED@TFS]

Wow you guys are on top of it aren’t you. All of this is good information, I’ll keep checking in. Parts will be on the way very soon.

[FFRSpec72]

I was removing my top end this weekend and I went to put the TPS on the new throttle body and no go, seems the holes for the 2 screws are not aligned, so I can't use my stock TPS with the new throtle body, what TPS does this throtle body take as I though there was only one TPS for 87-93 ? Anyone else try the TPS yet?

Also what do we do with the Idle Air Bypass connector since there is no place on the new throttle body for a Idle Air Bypass?

[FFSpecRacer]

Tony,

Mine bolted right up. Since you mention that yours does not have a place for the IAC, I'm wondering if you have the wrong throttle body as mine has the provision for the IAC also.

Throttle body should be TFS part number TFS-24570. I'd be calling Eddi to find out. A couple pics and I could tell if it is the wrong TB too.

[FFRSpec72]

Brain, here are some pics, the part does say TFS-2470 but where the label is placed looks like some other label was removed as the first surface of te box is removed (see pic of box). Here are some pics

Tony, do you have your heads?

[FFRSpec72]

Tony, do you have your heads?

Nope, was just doing as much as I can to get ready for them, as I had to replace wire harness as the 93 donor was getting brittle and causing issues and so while i was at it I was moving as much stuff over like MAF, throttle body etc and hit the TPS issue.

[FFSpecRacer]

That is not the right TB. Very different. Even the throttle linkage is different. That would not connect to a standard Ford throttle cable. Here is a pic of the correct one. Contact Eddi at TFS for an exchange.

[FFRSpec72]

Brian, thanks I got the wrong upper intake manifold also, so hoping we hear from Eddie soon so I can exchange these and get the right ones. Some one must have switched lables on the box.

[FFSpecRacer]

I wouldn't wait to hear from him here, I'd call him on this.

[johngeorge]

FYI, I ground down the IAC where it touches the upper intake a little and that made it fit.
