Thanks.

Got the car running last night. Had a few issues to work out before it ran well - timing and valve adjustments. Took it for about 2 mile drive. The Stainless Works mufflers are a little louder then I thought they would be at idle and under acceleration. The mufflers are their Turbo S-tube. At around 35 just driving, about the same noise level as my old Flowmaster setup. I'll try get a video of it running this weekend and post it.

Congrats! Cats will help quite the mufflers down if you like the sound but want it quieter.

I got the car back together and took to a local test and tune last Wednesday to try autocross for the first time with all the new parts and changes. Akron Sports car club has Wednesday night events during the summer at Dragway 42. Had a few issues. More to come on those and what I used/made to solve them. The plan has been before I started making these changes was to have the car ready for a DriveAutoX event here in Cleveland that took place last weekend. Learned quickly that my car is way more street than race car. Of the 35 cars there - I would say 2/3's were close to race car. I was the near the bottom both days in overall speed which was not a surprise. With all my changes, my 69 drives completely different compared to last year. More seat time will help a lot.
Here are videos of my best runs from Saturday and Sunday.

Before going to last Wednesday's autocross, I drove the car around my local area for about 150 miles. Didn't have any issues. At last Wednesday's event, found 2 issues with the fuel tank - the brand new cap O-ring split and started leaking - that was the minor issue. The other major issue was the vent was leaking during and after each run. I made changes to the vent line with the new tank and that didn't work causing a siphon effect. To fix this, I made a vent can similar to what you can buy (I would have bought one but there was no time for shipping and installation before Saturday morning).
Here is what I fabricated and had a local welding shop tig weld together. It's a 3" round piece of stainless exhaust pipe, 4 inches tall. One fitting is welded flush to the floor of the can and the tube goes up into the can about 1/4" from the top.


It's installed on the highest part of the truck floor above the rear end:


The vent line from the tank goes to the fitting flush to the floor of the can and the other one goes to vent - It's a 3/8 tube that runs between the tank and trunk floor to the vent that's behind the rear plate just above the fuel cap. I used this vent: https://www.summitracing.com/parts/tnk-vvr

This setup worked great and didn't leak a drop all weekend.

Here is an image posted on the DriveAutoX FB page - headed to the finish line on Sunday:

Glad the changes are moving you in the right direction. Dialing in the combination will take time but is part of the fun.

I had the car weighted yesterday for the first time so I don't have a before/after. This was with 3/4 tank of fuel since that is where I run it during autocross. I just wanted to get an idea where I was at.

Here are the numbers:
Total: 3386
LF: 877
RF: 905
LR: 792
RR: 812

I really thought I'd be over 3400 with all the stuff I added over the last 2 years. Had the fuel tank been full, I definitely would have been over 3400.
