Got to make three runs last night. Car ran better than I expected. My first ever pass in a FED was a eye opener. :) We forgot to check the tire pressure and I paid for it. I launched off idle and immediately got out of the groove. I held it ok and still made a decent run. Runs two and three were much better. :)
The track let me make single passes and also signed off for three of the five runs for the IHRA license. Really a good night.

First run ever. 5:92/110
2nd- 5:63/115 best of the three
3rd- 6:12/let off before 1/8.

I'm  needing to get the car down to 5:49 to get my class B license. I also have to get close to 5:50 to run SHRA NE/3. Looks like I might get there with the current simple combo. Fuel injection worked out great. It's still on the fat side. I need to get used to the car too. :)

I need to say thanks to @Roger. He has helped me a bunch.

Those are some good numbers from a little engine with a small flat tappet cam, low compression, and small heads. I'm glad everything worked so well; those fellas in the SHRA NE/3 might want to start looking over there shoulders to see if you're coming after them:) Enjoy and stay safe!

I'm really surprised at how it works too. Many told me the combo wouldn't work. To make it to 5:50 I'll have to change a few things but, I think it's possible. For now seat time will be the biggest time improvement. :)

This was 8/24/18. I have it pickled and on stands until my knee gets better. My son wants to try his hand at running it. Hoping to have it back out soon.

Had cert/license day at my home track today. My cert would have run out in March 19. Got the new cert no problems! Now I have to put it all back together. :)

I believe I saw in one of your earlier pictures that the connection from trans to rear is yoke to yoke through a u-joint. Is that legal? Is that considered safe?
Obviously couplers would be optimal. I'm asking because I have the same setup. Shielded within a steel tube guard cover.

that's what we ran for years no problem pg to a 9" everything has to be aligned  and the u-joint slips right into the yoke

Well, that's reassuring, though everything does NOT have to be aligned to the extent that I would think it would need to be with couplers. The u-joint interface would tolerate some left-right and / or up-down misalignment as long as the yoke bearing centerlines coincide at the u-joint trunnion centerline, where, as you say, the u-joint cups slip right into place. Mine do as well, but on my car, there is evidence that there has been at least one other drivetrain combination in the car at one time or another, because of visible mounting holes in the rearend upright that are not currently filled. I have no idea whether a line-up bar was used to set up my present combination.
 Thank you very much for your input on this. I'll worry about it a lot less now, hearing you've run the same thing with no driveline failures.
