The Shop Truck

1971 Chevy C20 with a custom flat bed.
Will this one go to 4th at WOT?
The 700R4 is controlled by the TV cable, when at WOT it mechanically can't shift into 4th. The 4L85E will be completely controlled by the Holley Dominator. I'll be able to tune shift points, lock up the converter in 3rd or make it go into 4th if needed. The new engine will also have a higher rev limit and still be making power well beyond where the current engine is so 4th may not even be needed on the strip.

Good so your tires will be good then
 
We ordered the engine yesterday! I ended up going with Fuel Injector Development 152lb/hr injectors from Motion Raceworks. We're still waiting for the fuel pump, it's been over a month now, but every time I call it's "1 more week"... Hopefully I get it in January so I can build the fuel tank.
 
Are you going to need to cage the truck now?
If I want to go faster than 11.5 or 135mph, yes. I need to find out what kind of cage I need, I swear whoever writes the NHRA rulebook doesn't want anyone to understand it. I won't push this truck past 10, but I'd like to get close and I should have the power to do it.

Oh yeah it’s an art form reading the rulebook
 
We're starting to work on the fuel cell. I was unable to find one that would work for what we're trying to accomplish so we're going to build it ourselves.
The Fuel Labs fuel pump uses the 10 bolt Aeromotive flange for some reason. I was unable to find a source for a weld on flange so we made our own. I'm pretty pleased with how it came out.

We picked up some 5052 1/8" plate for the cell and I spent the weekend learning how to weld aluminum... I still need work, but I'm getting better. I won't build the tank until I'm comfortable with my welds, but I've found some good YouTube channels and may sign up for a remote welding course if I hit a wall on my progress.
 
 
We worked on the Shop Truck some yesterday. We've had a set of Trique door latches for a while and decided to get them installed finally.
Old hardware removed:

While they are definitely easier to get to latch than the factory latches, they have more adjustability so I was able to get the doors to close properly and flush. I need to find some softer door seals (I got mine from Brother's) as it is very difficult to get them to latch from inside the truck currently. In the short term, I'm going to adjust the latches to give more room for the seals, but long term I'd like them to shut flush.

We also added a N2O pressure transducer so I can log that on my passes. We're headed to Friday Night Drags at Firebird this week so I'll see if we can get into the 12's with the slicks and minor tuning mods we've done.

We're going to start working on the tank today as well, my welds are looking fairly decent, not show quality, but decent.
 
I've also had the problem with reproduction door seals being too stiff until I realized the door seals on a GMT800 are the exact same design but very soft and squishier. So I bought a set right from GM and trimmed it to fit. No more door slamming

Thanks for the heads up on that! We loosened the latches up a bit and now the doors close nice, it would look better if they closed flush though.

Yesterday we cut up all the pieces of the tank. We decided our break wasn't going to be up to the task of bending 1/8" aluminum x 27" so I cut 6 separate pieces. We got the sides and floor all tacked together yesterday, hoping to finish welding that today (inside and out) and start working on baffles.
