American Motors Xperimental full frame

FWIW a Nascar runs 31 spline axles......



So whats the wheelbase now?

Andrew is right, on that the drive plate end, the axle is 1.5" and 24 spline, the axles Baddride is talking about are 1.5" 35 spline.

The wheelbase will end up being 104", 7" longer then the original 97"

Another great build!

Look forward to the updates.

Ohhh....sorry my mistake

Another FWIW.....a Nascar Busch (Nationwide) series car has a 105" wb and they run 190mph on a regular basis....the Sprint Cup is 110

Heres one don't don't see too often, a Dana 60 center section in an oven, cooked for about 45 minutes so the tubes would push in. The tubes had about .003" press, alittle tougher then I was hoping to get in, they are pushed in so tight I really don't seem like they will need to be welded LOL,looks alot like a 3/4 ton pick up rear.

[Dan S.]

What did you baste it with?

[Kenova]

Did you chill the tubes too?

What did you baste it with?

Sweat, plenty of sweat

[Ron S]

Did you chill the tubes too?

Ken

Yeah, still a really tight fit, as the tubes bottomed out in the housing and it cooled the tubes galled up.

Looks like there was enough room for some stuffing.LOL

[bonecrrusher]

Ron - dont know how I missed this - this is a badass looking project!!

[andrewb70]

Ron,

How did you fixture that damn thing to even begin pressing them in?

Andrew

[Ron S]

Its kind of helpful that a buddy runs a driveshaft shop. I gave him the tubes and snouts once I cut them to length, machined the snout to a .003" press, pushed them into the tubes, then dial indicatored them for straightness, and fixture welded and cooled them on the driveshaft machine. The welds a gorgeous. Getting the tubes in the housing required a hot housing, a cold tube, and a 1" grade 8,fine threaded rod, about 2' long, and 2 big press plates. The rod does one tube at a time, pulling between the snout and the flat spot on the inside of the housing, from the inside of the tube. Sweated my butt off ratcheting them in.

[Ron S]

Set the rear up on the frame, and put a wheel on, I have to admit I'm loving it. Will get the center crossmember and torque arm crossmember built tommorow.Hoping to get the body on Sunday

That is a lot of tire! Looks like another great build.

[Yelcamino]

Ron, the build is moving along fast! I know they're the same size, but for some reason the pictures make the front tires look bigger than the back.

[John Wright]

Wow...just look at those big ole rollers on all four corners....is my tire envy showing?

[Mike Holleman]

The next few steps are the ones I really wanna see. Never really seen an underslung chassis build in progress. I understand the concept but I want to see how it plays out. The Mustang looks lonely Ron. Take it out and give it some love before the snow falls. Wish I had some time to come help. I'm pulling the racecar apart and starting the 97 Firebird track car all at the same time.

those tires are huge!?!? i don't think you'll be able to get enough heat into them especially with a UTQG of 80. you might be quicker with something smaller or adding more weight into the car.
