Got a call from my engine builder today. They wanted the water pump to make sure it had clearance for the Enderle timing cover. The have to mill the front cover for pump clearance. My 2-piece ATI cover didn't have clearance for the gear drive.

As for the RCD gear drive, I got the rest of the story. They don't make their gear drive for an SBC with a BBC snout/post anymore.

I also got an update on the new Total Seal rings. These are the AP series rings with gas ports. I questioned them as that was what I thought I had previously. They stated these were the upgraded rings with more gas ports & DLC coating, great!

As for the health of the motor on teardown after 250+ runs. They didn't see anything alarming. They feel with my tune-up, maintenance & engine upgrades. They thought I could get my goal of 400 passes on the engine without major rebuild. There are only 2 items I may replace before the next rebuild is lifters & valve springs. This is what I was hoping for, a low maintenance 8 second engine without pushing the tune/boost. So far, it has been a great, consistent & winning bracket racing combo!

We're a little behind on testing the quad due to life issues. Hope to have video up of that.

Great thread! I love S/SS but have been bracket racing since 1982 and can appreciate anything. I have as much fun in a 15 second car as a 9.90 car and there's less maintenance between rounds! LOL!

(side benefit, this is the first thread I've seen in a while that wasn't highjacked by the self proclaimed genius)

Thanks J M!

I love all Straightline racing & we do it all with many different race vehicles. I know this isn't a bracket racing site, but I do try to share a bit. As I've stated, I'm primarily here for Stock & Super Stock.

While I have won races with the slow vehicles. I prefer the 8 - low 10 sec. rides. Although I have raced a mid 7 sec. truck in S/C & brackets.

As for your last paragraph, you may have jinxed the thread, but I don't care. He's the biggest D..Bag of the forums. Hence why he's been banned/banished or put in time out in numerous forums, including Class Racer.

1700/781L, thanks you for taking interest! It has gotten more views than I thought for a bracket race title.

Been busy with getting 3 race vehicles ready for the upcoming season starting the end of Jan.

I picked up the Camaro's engine today & worked the rest of the day get pulley alignments measured with parts ordered to correct. All work is being done outside the car. Hope to finish everything & disassemble accessory drive & install the engine at the end of the week.

The quad is being tested on the streets of Mexico this weekend. Short hits to start tuning the clutch. The following week is headed to the track for testing on the engine & more clutch tuning.

The drag bike is pretty much ready & will be run the 1st weekend of Feb. We have a TnT on Fri. with the 1st two points races on Sat & Sun. This will probably be when we bring the Camaro out; a big maybe will be the TnT at the end of Jan.

In my defense, I thought you had to say it 3 times before he would appear, like beetlejuice....LOL!

We got some testing done in Mexico today. My big son was riding. This video is a short hit to around 300' getting into 3rd gear. As you can hear we had a Bogg on the 1-2 shift. We made 4 hits today & the last one we got right. We never got it to hook in 1st gear, but it got better as we lowered the tire pressure. The last run was pretty darn good for the conditions & ran it through 4 gears.

The plugs showed we were fat & we will wait to lean the power jets out once we get some 1/8th mile runs on it at a slightly lower altitude.

In preparation for the track next weekend. We took 20 lbs. of base pressure out of the clutch. We also had a little slippage on the 3-4 shift & we added 5g of weight to 3 of the lock-up arms.

Got the 1st heat cycle on the Camaro engine this morning. I must have done something right with the new Terminator X EFI install & tune.

I was alarmed with the lean AFR reading around 25.00, I think I figured it out. I didn't have the mufflers on & that caused a false lean reading with the O2 sensor. Holley wants 18" - 22" of exhaust after the O2, I only have about 6" with no mufflers.

Back out to the shop to fix the issue & put another heat cycle on the engine.

It was a pretty good day of testing with the quad today. We were .2 slower on the ET I was hoping for a baseline.

The clutch was a little loose & showed in the 60'. It will probably be good for the Kingman Street Drags with the set-up. We are going to test at the track probably in Feb. or Mar. & add some base pressure for track testing.

We started with our 1/4-mile final gear ratio of 1.94 when testing in Mexico. Today we started with a 2.06 ratio & it was a bit too much rpm. The next testing will be done with a 2.0 ratio & should put us in the sweet spot.

We couldn't get a good plug chop the way the track was set-up today, but I'm pretty sure we are still fat. We did lean out one power jet on one of the cylinders. It was running fatter than the other.

Got the Camaro loaded today & headed for the track tomorrow. T&T tomorrow & points racing Sat. & Sun.

Hopefully all the new updates work as intended. We have a very conservative tune loaded in the ECU. We have pulled about 5* of timing in the boost range. Should be able to still run low 9's in the 1/4. If everything looks good, we'll start adding timing in small increments.

Curious what the rear gear change will do with the converter stall & fallback rpm.

While the updates to the Camaro wasn't meant to make it quicker or faster; it did happen. I got out of the throttle around 4.5 sec. into the run & ran a 5.6x @ 123+ mph to the 1/8th. We part throttled to the 1/4 mile & went 8.8x @ 143 mph. That's .1 quicker than our best at both distances & that was getting out of the throttle/part throttle.

I changed the rear gear from a 3.89 ratio to a 3.55 to knock some rpm out of the finish line. I guess it liked the change. The converter flash stall raised from a little over 5,500 rpm to a little over 5,800. The shift drop went from 1,000 rpm to 600 rpm drop. Pretty much what Kevin @ Hughes Transmission predicted.

We did have an issue with the fuel regulator or fuel pump not keeping up with the 1:1 ratio of fuel pressure vs. boost. This was the 1st time logging the fuel pressure & oil pressure, we used analog before. We could have had the issue before. Regardless, we have an upgraded brushless Aeromotive pump on order & have to upgrade the regulator with a bigger return seat, they have a kit for it.

We'll see what happens next time out.
