Holley Sniper on 700 hp big bock

This is a Holley Sniper X Flow on a 505 inch Mopar big block. This engine is a little more radical than most street/strip builds. The owner went with higher than usual compression ratio, used Trick Flow 270 heads and installed a 264/268 solid roller cam. The nice thing about the Sniper+Hyperspark combination is that we were able to build ignition and AFR tables to make the car fairly drivable. The owner did need to swap the factory four speed for a 727 since there just wasn't anyway to drive the car with a clutch. We did this project a couple of years ago. I can drag up a few more pictures if there is any interest. It is a B body but that shouldn't matter in this forum since the focus is on the fuel system.

Hello Andy, I have read a number of your posts and found them very interesting. (including your Duster build) I am currently installing a fairly stout 470 low deck in a street/strip 68 Dart. I have the Holley Sniper X Flow + the Hyperspark combination, but this will be my first time going with fuel injection. Any pointers in regards to the install and initial set up of the system other than what is noted in the directions? On this car and your Duster, did you start off with the Wizard as the initial setup?

I had the motor on the dyno for break in and to check for leaks (glad I did as the rear main leaked and need to be swapped out) and we made a few dyno pulls, but used a 950HP dyno carb as I didn't want to try to hook up the sniper on the dyno. Attached is the initial dyno sheet (was a little lean on the pull). Any insight you can provide on things to pay attention to and look out for on the install and initial start up? Thank you in advance!
