I am excited to announce that the big engine rebuild project that we started back in 2011 roared to life tonight. Below is a screenshot of a graph showing the the exhaust gas temperatures (EGTs) for about a minute of running time.

The graph shows that the front cylinders were running a little hot, around 1354 – 1384 degrees F at a mere 1774 RPM, even though the ambient air temperature was only about 50 degrees F. So we have something to investigate. We don’t usually see EGTs that high unless we are screaming through the top end at 125 MPH!

I had almost worn the battery out by the time the engine started. It turns out you need A LOT of juice to turn over an engine with springs that have such high pressures.

I was able to run the engine long enough to check the timing, which was at 30 degrees. We’ll probably want to run it up another 2 – 6 degrees, but for a first time startup hitting 30 degrees is pretty good, so I’m proud of that.

Anyway, I’m over the moon that our 455 (467 total displacement) engine fired and successfully warmed up. I’m looking forward to starting it again in the near future, and I’m really looking forward to taking it down the strip in just a few months.

    Good job Phil!! I know it feels good to hear it roar to life after all the efforts you put forth. I’m anxious to hear how you make out at the track. Keep us posted!

    Congratulations on getting to this point in the project. I know you’ve put in a lot of wrench time.

    BTW, if there’s video of you standing over the engine compartment, laughing maniacally and screaming “it’s alive! it’s alive!” please post a link.

    Very funny! I actually tried making video footage using 3 different cameras the first time I tried to fire it up. I spent 30 minutes setting up the different angles and making sure they were all recording and every time I got back to the task of getting the engine to start, it wouldn’t. So I gave up on getting the cameras to roll for this time 🙁 I had wanted to capture that moment where I have a maniacal look in my eye because I have controlled and harnessed the power of the V-8. Unfortunately, you’ll just have to take my word for it 🙂
