Today was dyno day. I have a video if I can ever figure out how to post it here. Best out of three pulls was WHP 276 and WTQ 352. With a Performer intake, a Performer Plus cam, and free flows I can't complain at all. The Holley Sniper was just about dead on the money. Just a few minor tweaks on the timing and she was good to go. Color me happy.

Not bad at all. I’d be interested to know what it wanted for timing.

Another minor tweak to the Hornet today. I did not realize that the linkage from the primaries to the secondaries on the Sniper were set up with a 1:1 lockstep ratio. As soon as the primaries would start to open so would the secondaries. For street use it was coming on a bit too strong from a stop. Too easy to chirp the tires and get the attention of the local police. I picked up a Holley progressive carburetor linkage and set it for 35% on the primaries before the secondaries start to open. What a difference that made. The Hornet now has very nice street manners until you hit the 35% mark at which point she becomes a little beast. One of the best modifications I have made so far. If your thinking about the Sniper for street use then I suggest you think about do the progressive linkage too.
