Seems a little slow...

Okay, so I just got back from the track. I didn't uncork the exhaust tonight because I didn't want to fight with getting it put back on in the dark.

Here are the changes I made prior to going to the track:
Swapped the 650 DP back on
Lowered the pinion snubber 1" so it's 1.5" off of the floor
Pulled the Mallory 110 pump off and put on a 140 + regulator right next to the carb...set for 7.5 psi

Here's the best time slip of the night

60': 1.918
330': 5.660
1/8 ET: 8.763
1/8 MPH: 79.46
1000': 11.452
1/4 ET: 13.736
1/4 MPH: 98.65

The fuel pressure now dips just below 7 psi going through the traps and the RPM is right at 5800 to 5900. I'm still running the Action + intake and this is with the exhaust on, so I figure that it should run low 13.6 to high 13.5 with open pipes, as I picked up .15 last time dropping the pipes.

Any thoughts? I didn't get an opportunity to mess with the squirters or cams (running the blues in #2 front and back), or try clamping the leaf springs. Those would be my next steps.

Okay, I just looked at your original post. It looks like you picked up more than a tenth in the sixty foot, which is close to what you should be running with the E.T. you are running. I expect the car goes fast with the exhaust uncorked, so I think the MPH is down due to the exhaust being on. I think you also lost mph when you went to the dual plane intake. Am I correct there? Also how were the weather conditions, was it hotter than the night you ran your best? I think your on to something and are moving in the right direction. You may want to try and build a better exhaust for it so that you dont need to hassle with uncorking it. Besides if you dont put an 18 inch extension on the header then you loose power. I know your getting a bunch of advice but I admire the methodical process you are approaching this with. If your still willing to try some new things I have some more ideas that are cheap to fix. First off someone mentioned advancing the cam, which I tried once and my sixties improved greatly, but my car had the nitrous converter in it and needed the extra grunt. So I have tried it on other motors and ALL of them picked up E.T. The next thing I would do is go back to the Torker, which is a good intake. Then I would play with the carb and wait for better weather. I think as the weather cools, you will be surprised how much it has picked up with the changes. Leave that 650 dp on it, its working better with the combo you have. I think your motor is very healthy, it wouldn't repeat good numbers over and over if it was hurt. This car runs hard for a street 318. Good job.
