Well, I finally put this thing on the scales. With me in the car, it weighed 3900 lbs. I can't say I'm surprised that she's a piggy. The good news is, it can only get lighter.
Now, the axels can come out to be upgraded to 5/8 studs and the converter can be pulled for a restall.

I feel the same way about drilling holes. Hopefully, you make it out this year.
Actually, on the 9.94 pass, the converter was locked at 130mph. I think it will still pick up with the tighter converter though. The RPM through the traps is down around 5300 with a locked converter.

With the 2b leaving on 4.5psi I went 1.64 60' and it took probably 2 seconds to build.
The 1A I went to the track and only got one pass. Left on 2 more PSI and 60' 1.64 on top of that it took about 1 seconds longer to build the boost.

Just saw this, I'd hate to say it but I think you might be making a mistake tightening the converter. I didn't know you were locking the converter, I would try locking the converter sooner if possible. A little slip is a good thing it will help you multiply torque and get you down the 1/8 quicker.

Thanks for sharing your first hand experience with a very similar application. I'll bring up your experience when I chat with circle d again.

Sounds like we are in the same boat with the converter as well. I have the 2b and have been a best of 1.38 60' off the footbrake. Circle-D thinks they can get it tighter up top without sacrificing my ability to footbrake the car. It's not picking up the MPH it should when I turn it up. I go from 115-116 traps to a best of 118.8 and it took almost 5 lbs. to do it. I am guessing the slip on the converter is what is holding my Gen 3 rods together though. I am contemplating a transbrake this winter though since I am putting a good rod and piston in it.

Btw, Your car is putting work on those gen iii rods! Damn!

I am shocked this engine is still alive. It's been in the car for 4 years now and I beat on it pretty good this year. Anxious to see what it looks like when I tear it down this winter.

I haven't sent it in yet. I planned on racing the car a couple more times this year but the trans developed a leak from the pump seal. I am trying to decide if I want to do a brake or not now.

Be sure to post up about your shortblock findings. I just subscribed to your thread.

Well, I just received my new 252mm converter from circle d. We ended up trading the 258mm 2b in for their new 252mm converter. To tighten up my original 258mm converter on the top end would have sacrificed some ability to footbrake and launch the car. This new converter supposedly will be tighter up top (sub 10% slip) and footbrake better than the 2b.

It's been a while since I looked at the build progress. Congratulations on the 9's that freaking awesome!
Finally dropping the car off this week to get the intercooler and down pipe routed and welded up! Pretty excited to be honest!
