I absolutely DON'T RECOMMEND this. It's putting a nasty bending moment into the arm and lower pivot shaft. As the suspension goes through its travel, the arms don't remain perpendicular to the hub carrier. Some compliance is necessary.

If you want "solid" on the outer end, use rod ends or spherical bearings.

Yes - I found that out when I cycled it. We are working on rod ends.

I ran my control arm by some race car engineering type's and they were less than impressed. A Ford GT control arm was presented so we copied that form around our pickup points. We will cut one next week, but still plan to run FEA. Compare the two - this one is built as an I beam rotated so it's strength is against braking force.

2.2lb with no hardware.

We pulled the engine and are final fitting the bell housing and transmission. We got the housing to block to .002.

We are going to run an electric fuel pump so we have been working on the plumbing. We have been round and round over the fuel cap situation. I do not want to run the internal cap, but I cannot risk spilling fuel at the track. We cut a new riser, offset the inlet, and were able to include a return in the riser. We found a suitable cap and vent from one of the racer supply places and we will drill the top of the cap and screw the vent into the top of the cap. I wanted to run it recessed into the body, but was voted off so we are cutting a new riser which puts the top of the riser at the top of the body.







The cap seals with an o ring -they won't like the roll bar

And to think, this all started with cutting a hole in the drivers side floor. Is there an ETA (date) for when this thing hits the asphalt again?

Yea it's a lot of study and a lot of work, but a great hobby. The track opens back up in March and we have a lot of areo stuff we want to try on the Mustang so we are really moving right now on the FIA. Gene thinks we can have it by the end of summer, but I am a huge obstacle. I still don't have a complete widened front suspension, widened rear suspension, raised steering, new rear end, or aero to hold it down. If I can't get the control arm thru FEA I will be kind of screwed and will resort back to steel, but it will take more time to come up with one. The modeled arm with the ATS upright has a really good motion ratio.

We are going to try and start it up soon so that will be kind of cool.

We'll get it

Can't beat FEA for suspension components. A massive amount of 'development' going into your car....great to see. Is ERA interested in any of your seemingly logical improvements?

nah - ERA builds beautiful Replicas - I got a hacked up track car.

Our Diff finally arrived. We start re-assembly tomorrow.



We cloned the rubber engine mounts into solid ones.



Finishing up welding in the down tubes



We are working on widening the rear track back to it's original width without using wheel spacers. We need to move it 1/2 inch. We put the upper trailing link in double shear which allows us a little movement outboard. The gusset tying the main frame rail to the 1" body support has to be relieved else the rod end will bind against it as it moves outboard. We just drilled a clearance hole in the gusset. Once we can cycle everything again we will space the trailing link to the best fit location.



I checked the weight thread and the 351 setup we pulled weighed 520

351w w Lakewood & clutch 520 lb

This Engine, Bell Housing, Clutch, Transmission, & Diff weigh 510 lb.

I'm expecting the rear cradle assembly to come in around 252 ready to bolt in. That would be a 92lb reduction in the rear cradle assembly.

Can't wait to reassemble and weigh. Last time I weighed with steel wheels and no fluids we were at 2088.

Been talking to Watanabe - another science project fraught with risk ($$$) - LOL. If they would just publish basic dimensional data it would make things so much easier.

Really enjoy working on your car Bob.

On the way home it occurred to me my numbers maybe a little optimistic. Brent installed the flywheel when he assembled the motor. The Quick time bell housing was a disappointing 33 lb and the rest of the clutch should have been 10 so all of it bolted together should be around 550lb.

30lb heavier than the 351 with bell housing and clutch.
