It hit the tires pretty hard, and brew them loose. Had to pedal it, and it still spun before it hooked.

I was just curious to see if it was slipping with that size shot. You running a 73n jet in the nitrous?

The difference between my 10.20s and your 10.60s is mostly all before the 330' mark. You get that thing launched and you will be right there.

So you are picking up 9 mph on a 73n jet and I typically pick up 11 to 12 on a 63n jet. I bet I am a lot less aerodynamic too. Makes me think your converter is slipping pretty hard on the nitrous.

Yea I am using a lot of mismatched parts. Carb, efi cam, and trans/converter. Its pretty much got a jumkyard trans in it with a valve body too. It doesn't build much power above 5500-6000. So I plan on some upgrades over the winter to the engine, trans, and suspension.

I currently have 63n/51f in the car. The plugs look great. I pulled 6 degrees but the timing mark on the plugs look like I could at a degree or two back in. Also the fuel shadow is darker than it might be because I drove it back to the pits. I hate pulling plugs out of a hot motor.

I am running a 73 in oth with 5 psi fuel and only 6 lbs in a 85* bottle. Not sure on the bottle pressure as my gauge had to be unhooked, because I had a small leak in the hose. A local 1/8 mile track just reopened after 35 years of being closed. So I want to go and do some more testing.
