Move to MT...LOL....everybody else did.

I have been reading where the government in California is trying to hide the fact that many of it's educated/technical people have had enough and are moving out. They have lost something like 60% of their comuter IT and the companies are going with them. California is going to have a hard road ahead. Their moto is to convince other states to impliment the regulations they are implementing. This way there would be no reason for anyone to leave.

 

do you think that all the work you did would change the rpm limits if so high. I asked this question a long time ago here about making a 4-bolt 400 and the only respons was no there is no enough meat? well done

 

Hey Tim I was thiking about the 434 stroker kit and I was curious if you would need the block to be cut in some places to accomodate the much longer stroke? Thanks for the help.

 

No extra machining required. There is a lot of room. We are currently assembling a long block, I will try to start posting pictures of the assembly. I am a little bias, but the stroker crankshaft and "H" beam rods do look pretty impressive assembled in the block.

 

Dan don't you need to use the 460 TFI distributor in the 400?

The projection stuff might be bolt on but I think in the long run using mustang Mass air SEFI parts would prove benificial in the fact if something breaks all of your parts are at the local parts store.

my EFI setup

-92 Mass air Mustang harness, sensors, and ECM
-2002 90 mm mass air from a lightning
-30 ish lb injectors
-460 TFI dizzy
-CHP power elbow for throttle body
-75mm or 80mm throttle body
-E2000 fuel pump
-intake machined for 351w fuel rails
-A TwEECer to tune everything

Everything is planned out. I just need the green to peice it all together.

 

I have a 351W EFI Billet dizzy with a gear for a Cleveland.
Mustang Mass Air Harness, A9P ECM, Lightning Mass air calibrated for 42 # injectors, 8 ea 42 # Injectors, Billet Fuel rails, Bungs, Fuel Pressure regulator.

I need all the sensors, including the O2 sensors, fuel pump, fuel lines, a Tweecer, and the converted manifold, and probably a handful of other items, including some intake air tubing and cone filter.

I am also looking for the 460 throttle/kickdown cable bracket.

I don't plan on retrofitting until late Fall, since the truck is running great with the Edelbrock carb.

 

Have you checked out Howell yet? They have a kit for around $1200 and is better than holley.

 

Jopey: Am following the EFI discussion, Need a web address for Howell so I can go look.

Thanks PWRPROD

there ya go

 

I have been trying to get this discussion moved the the EFI thread, without luck. Since it is here, I'll add my 2 cents.

All the EFI systems that use a 4 barrel throttle body on a four barrel manifold are either Throttle Body Injection or Multiport Injection systems. The Holley and Accel systems are bank fired multiport speed density systems. Throttle Body Injection is not much better than a carburator. Multi port is better, and for all out racing Multiport Speed density is preferred. For every other use Sequential port injection that uses an EFI electronic distributor and a Mass Air is best because the mass air allows feedback control of the mixture. The electronic distributor supplies a crank trigger signal for timing control.

To use a Mass Air meter with a 4 barrel throttle body, would require total fabrication of the air intake system.

The 5.0/5.8 L Mustang EFI system is a sequential Mass Air system and is probably as good as it gets for conversion of a carb motor. There are adapters that enable you to use a Mustang TB on a 4 barrel manifold. This is the Power Elbow.

The disadvatage is that you are limited to the size of the 5.0L Mustang TB.

There is another choice. That is the Throttle Body Adapter shown here.

This is a slick piece. It is expensive, and I am concerned about possible inteference with the dizzy in our motors. For this reason, I chose the 460 Upper Manifold.

The next problem is the manifold itself. There are only two manifolds on the market today for the 315M/400 motors. They are both Dual Plane manifolds. An EFI conversion should have a single plane manifold, because the runners are all at the same level for installing the injectors and fuel rails. You could get a used Holley Streetmaster Single Plane intake, but that has some drawbacks in that the length of the runners is different between cylinders.

That leaves us to look to other motors for intake manifolds. You can use a 351C manifold with adapter plates from Price Motor Sports. They are expensive also, and the Weiand 8205 is no longer in production.

The best 351C manifolds are for 4V motors and not well suited for 2 V heads. The new Edelbrock RPM Air Gap intake looks like it will accept bungs and fuel rails without too much problem, in spite of the fact that it is a Dual Plane intake. However it also has different length runners.

I happen to be in a fortunate position as far as manifolds are concerned. I have CHI-3V heads on my motor, and CHI makes a high rise manifold that mates with their heads. This manifold is nearly perfect for an EFI motor, since the runner length is equal for all cylinders. CHI makes a kit to adapt this intake to a 351M/400 motor. This manifold is for a 9.2 inch deck like the 351C.

CHI made this manifold because the knew about the scarcity of decent manifolds for the 351C motor. They didn't know that the rest of the 355 series motors are much worse off.

 

Dan you need to be sure your right here because that elbow works with TB's up to 90mm. Thats a pretty big throttle body.



Which Mass air you using from the lightnings?

 

The Lightning Mass Air is 90mm. It's calibrated for 42 # injectors.


Who makes 90mm injectors. Does BBK or Accufab make them?

 

you have the tables for the 90mm MAF for the lightning yet? I take it thats one from a 2002?


Never seen a 90mm injector. but alot of manufacturers make TB's past 90 mm for mustangs.
