Up on the jack stands and ready to drop the old gas tank. Since the shop is full I am relegated to working in the driveway. I think I can handle that. The new Holley pump has been installed in the tank. The stock tank vent is capped and we will fab up a vent from the pump. A roll over valve was installed in the pump. This pump will support 875hp with EFI. That gives me a little room to grow. Edited by pit crew - Jun/02/2018 at 4:20pm |

The new tank is in, the plumbing and electrical work all done, and it runs..... Just have to get the vacuum line for the transmission hooked up and we are ready for a test drive. The Holley in tank pump is so quiet I have a hard time telling if it is running. Nothing like having 4 or so extra gallons of fuel onboard. |

It's ALIVE. Got her started up and went out for a test drive. I am stunned. It is like a whole different car. Throttle response is insane and the acceleration is crazy. I have scheduled a dyno tune for June 22nd. I will take some video and see if I can figure out where and how I can post it. Putting the pump in the tank was a very good move. Talk about quiet. You can hardly hear the pump at all. What a change from the MSD in line pump. What a difference going from the MSD Atomic to the Holley Sniper. The Sniper is a crazy good upgrade.

^you're running a Performer intake? Just to pass on the widely accepted "internet info", lots of people have complained of tuning troubles with the all-in-one TBI's on dual plane intakes. I have no first hand info, but I've read enough second hand info that it might be a good idea to have a single plane intake on stand-by for the dyno pull, or maybe think about trimming the divider down under the TB of the Performer. ^you are probably already aware of this stuff, I just wanted to mention it in case you weren't and have noticed some tuning hickups since the TBI swap. This is another very nice build by the way Thanks for taking time to post it! |

Big 3 Racing (B3R) http://www.big3racing.net/ has been dealing with performance in all forms from the stone age which is why we are putting it in their capable hands to do the dyno tuning. Stay tuned (pun) for details. Just a SMALL sample of what goes on at B3R. Edited by pit crew - Jun/08/2018 at 2:28pm |

First outing with the Sniper installed. Off to the Schools Out car show in Independence Ohio. This is a rain or shine show so the weather held down the attendance. |

I thought you would be aware of it, just didn't want you caught off guard if you weren't Nice video by the way, so, what's your plan to beat that 1200hp Mustang?
