Chris? What does that thing weigh?
With the added 3rd member beef and 35 spline axles, I’d guess 3875 lbs with me in it (was 3825 lbs previously)

Looked like fun.

I didn't realize you had another transmission - handy hehe.

Duke sent me a couple of logs, fuel pressure was a tad askew. I'm sure you're aware.

How did it feel on the hit and the 1st to 2nd shift? I think you have a bunch left once you get some little stuff sorted out - the tune is very conservative.


I'm envious ;)

Built TH400 is sitting in the garage! Already started taking the hurt one out. Hopefully by this weekend it will be out/in.

Fuel pressure did drop a little because it was still with one Walbro 450 running. I couldn’t get the second wired correctly to get the Holley to trigger with a relay. New relay should be here today.

1-2 shift felt great. All the shifts felt great.

In da 9s yet?
I certainly hope to be closer with the new trans in.

Foot brake at 3200 rpm could build about 5 psi. Trans brake on the built trans should make more 😉

No wheel spin from 1st to 2nd and launching was my intended question lol. If it ain’t wiggling when it shifts, then you need more power lol.

There is an easy way to verify your second pump is coming on when you want it to. Can be done at key on engine off.

Keep her going and git r done👍👍

No wiggle on shift, or launch. Figured it was severely hurt and I was loosing power through the trans.

For whatever reason, with the relay I tried using the second pump would stay on the entire time the key was turned to ignition. Will re-visit today.
