Re: my 50 build... why not?

I still can't get a bunch of pictures from last year up. I tried uploading them by adding the attachments on here and it says no security key.

Well, as for an update, i set the pickup on medium wastegate spring pressure, and that got me to 761whp @ 16.5 lbs on a heartbreaker dyno. Played around a bit on the street with some drag radials, then went to the track for a couple 1/8th miles. After sorting out some things and only time for 2 passes, I ran a 6.40 leaving on the foot brake. A month later, I got it ready for the raceweek. Hands down one of the biggest bucket list items I've ever wanted to do. Goal was to run a 9 second quarter, and complete the week. And both of those I was able to check off.

First day, I ran my 12 second slip just to turn in and then stuck my foot the whole way down the track and cracked off a 9.87@140 my very first 1/4 mile ever!

Here's a day 1 coverage video. You can see the pickup in the beginning as he is talking, then the 9 second pass is at 5:20.

After day 1, we camped out in the hotel, woke up at 5 and packed up the pickup and hit the road to Denver. We all had a route to follow and hitting checkpoints along the way. It was brutal with no wind and temperatures well over 100 degrees. No a/c, a 200 degree trans and engine below your feet, and a lot of hot water. My dynamat even melted and stuck to my buddies sandals. We made it to golden Colorado at a sonic, then I pulled out 3 jets out of the front of the carb as it was running very rich. Made It to the hotel, and unpacked everything again till morning. Woke up around 6, stopped at Walmart for a few supplies, then headed to the track and set up, swapped the tires, and got the first 12 second slip handed in again. Let it cool down, then went back for the all out pass again. Ran a 9.90@138!

Here's day 2 2:15, and 7:45 is the pass.

After the race, we went and grabbed some wings and hit to the mountains. Temperatures were hot again and trans was getting hot alongside with it. We had to pull over many times. Got rolling after a few hours on some skinny two lanes and got a flat tire. Somewhere we picked up a bolt in the radial. Switched out the radials for the drag radials and finished the drive to pueblo for another night of sleep.

Day 3 we had a little relax time to check things over, pulled the carb off, cleaned it as I had a sticking needle and seat, and added 2 more jets. Racing started in the afternoon, got my 12 second slip turned in again, the tried for the 9 second pass. Managed a 10.17@135, and was a little rich. Didn't wanna waste more time and risk braking anything, so called it quits. Went back to the hotel for the morning drive to great bend Kansas.

Day 4 drive was again brutal as it gets. Made it about to Scott city ks and everyone was running real low on e85. We had to make a little detour to pick up a spare tire about 50 miles out of the way. Made it to the hotel again, showered and started on the cold beers.

Made it to the track the next day with only about 5 gallons left. One of the guys in my group had his dad bring down a couple hundred gallons of ethanol from Nebraska for everyone. Got my 12 second slip again, then tried for my 9. Got a 10:24@120. It started breaking up, so I changed the plugs and added another jet, then got a 10:14@136. Called it quits and headed for Nebraska. Just got out of the track, and noticed my oil pressure was low. Putted up to Kearney, stopped at orileys, swapped out the electric gauge for a mechanical one, and it read fine. Wheew!

Day 4 @ 9:15

Day 5, washed it up for the first time, headed to the track, got my 12 in, and again tried for an all out pass. Just shifted into 3rd and it felt weak so I let out. Got to the end, turned around and it started knocking. So from that, I knew I did have a oil pressure problem.

After I got home, pulled the motor out figuring my thrust was wiped. Pulled the pan off and metal... everywhere. Lol. Thrust was fine. Ruled it out to hard braking and acceleration with a stock F-body oil pan. Turns out it's a fairly common problem.

All in all, it was the most fun thing I've ever done, made some great friends, and created a lifelong yearly event. I highly recommend going to watch this every year. The people's stories and cars are unlike anything I've ever experienced.

The motor is almost rebuilt now. Ended up with a little higher compression pistons, new Callie's rods, and a forged Callie's forged crank. Transmission I had gone through to look things over. Added a billet input shaft, and a few other little things for reliability. Lastly, I took the truck to 417motorsports in Springfield Missouri to have a 8.50 cage and a parachute mount installed. I should have all the parts back in February. Still need a different converter, upgrade to 35 spline rear end, and add sommore datalogging to watch over things. Hoping to see over 1000 to the tire, and run an 8 second quarter this year. Goals!!!
