Wow, Todd!

As Iíve e followed along on instagram, this thread is the first time I saw it from start to finish!

Such an amazing job with super attention to detail.

Best of success to you, as long as you donít line up next to me. :D

See you at the track!

BTW, did you know the NHRA is considering an 8.60 class for a national championship? Apparently, theyíre looking to tap into the very popular 8.50 index racers and the drag and drive folks.
No throttle stops or delay boxes. Basically, run what you bring as long as itís a door car. Youíd fit in nicely!

Thanks Pete!

I've since decided to leave 8.50 index to run the local Top Sportsman series. But that would be great if NHRA added a similar class.

Sorry for the lack of updates.

Came home from the show and began to work on the chassis setup. Found the rear shocks were not sitting down at ride height length so I had to swap from the 80 lb coil springs to a 70 lbs. Put the car on scales as well as measuring and plotting the instant center.

Next up was to put the car on the chassis dyno to work on the efi tune. Got the tuneup almost done when we heard a noise in the valvetrain and aborted any more runs. Took the car home to investigate.

Pulled the passenger valve cover on the dyno and found 3 of the small bolts laying in the head that attach the exhaust stand to the intake stand.

Got home and took it all apart to inspect the thread inserts in the heads. False alarm, all was tight and threads were good. Can only assume those small bolts just never got tightened completely.

Next up was to finally put all the safety gear in the car. The seat belts were first, but it's a project. The seat has to come out to be able to reach the bolts for bolting them in. The driveshaft enclosure is really close to the seat, so it and the driveshaft have to come out to be able to unbolt the seat.
