We got the 434 put together last week. It took longer than I thought it would (doesn't it always?). It took more work because of changing over to run the Ron's Toilet system with the Primer Plus system. I hate plumbing.
We ended up being able to run the Harold/Lunati cam with the 1.6 rockers for .730 lift. We installed it at 104°. It sounded nasty, and the throttle response was unreal. That toilet with alcohol injection turns the throttle almost into an on/off switch.
Worked on it until 4:30 am Saturday. Got a few hours sleep, then loaded it for some test hits at the track in Dyersburg Tennessee where there was a S10 meet/race. I don't think I'll ever race there again. The right lane caused EVERYONE of us heading toward the right guard rail before the 60' timer. I talked to a couple of the regulars who said they set their cars up to compensate for it. The left lane has a dip just after the finish line which caused chassis cars like mine to get all out of shape if you got on the brakes before hitting the dip. There isn't enough shutdown length for quick cars if you wait until after the dip. Oh well.
My truck sounded really good, but I attempted the right lane twice... almost put it into the wall and had to let off. One pass in the left lane that taught me about the dip, luckily it was after an aborted pass. My 4 link was no where close to where it needed to be for the increased power.
Video of the pass in the left lane.

Yesterday we unloaded it at my friend's shop and we scaled the truck, reset the IC location and ride height. He called a friend of his that owns the 1/8 mile track in Jackson TN. Scott, the track owner, said that we could come out and make some test hits for a couple of hours. He would prep 1 lane for me. No time slips or scoreboards... just get it to leave and go down the track.
The track was prepped way better than either of my local tracks up here have ever been. The truck started out by hitting the slicks so hard they went into tire shake, but it went straight and quick. We started adding air until we were up to 11.5 psi (up from 8 psi) and tightened up the shocks. It was leaving very hard, once down track it was on rails. My friend took a video of each pass. Once I get them I'll see about posting some of them.
I found that I have to get the converter tightened up. It stalled at 6350 rpm, and shifting it at 7000 rpm only dropped it back to 6500 rpm at both shifts. I've already called PTC and I'll be sending the converter back for them to tighten it up to only go to about 5900 - 6000 rpm on the drop back.
Sorry this is so long, but I'm pumped. lol
