Well I just got home from the drag strip. The truck motor had it's first drag strip outting. I only ran it to the 1/8 mile mark as it developes a rather severe vibration in the chassis around 95-100mph. I have some chassis tuning to do and need to have the convertor tightened up quite a bit. It's stalling at the hp peak,(5900) rather than the torque peak, (4800).
All in all it was a successful first outting, it ran a 6.53 in the 1/8. The truck picked the front wheels up 6-8" on launch but then wanted to go to the left out of the groove and would spin a bit until I was able to wrestle it back into the goove. I believe there is a few tenths left I can knock off once I get everything straightened out. Dave

Nice going Dave. Thats some power as no offense meant but thats like pushing a shoebox down the track and that takes much hp. Ron

Not bad.... whats that thing weigh.... you got out..
had some fun beating on it and made it home in 1 piece...
what do you have for rear suspension... trying to
figure out why its going left on the launch... either
a brake hanging or it has too much preload but if
I remember its a leaf spring.. are you running Caltracs

Ron; It's more like a barn door, 38.5 square feet of area. Mike; I built a 4-link from scratch a couple years ago. I'm sure it just needs some adjusting. The vibration I think is pinion angle under load.
All in all it ran fairly well for an untested (at the strip) chassis setup. 3860lbs. Dave

4-link... sounds like you need to move the pinion angle
(4-links like 1* or less but not zero) and reduce
some of the preload on the RR... my buddy has a 52
ford PU with a bore 460... he runs 11.50 with 1.4x
60' times.... he's a couple pounds heavier than you
and I mean just a couple... good job... get the 4-link
squared away and you'll pick up(no punnn....lol)

Checked the pinion angle today and found it was 3 degrees positive, I adjusted it to 1-1/2 degrees negative. Drove the truck and it ran much better. I've got to sit down and watch Billy Shope's 'Just Suspensions' again and then adjust the 4-link. Dave

I'm hoping it picks up a bit more before I'm done. My goal is to have to slow it down. Dave

Dave, are you saying negative pinion angle is down or up in relation to the driveshaft intersection at the pinion shaft?

Cab; Down for negative, up for positive.
I've got to round up a couple of scales to set this 4-link. Dave

Dave, I hope you have a good aftermarket and well balanced driveshaft under there. That kind of power and those kinds of speeds demand a quality d-shaft.

Dave; I had a custom shaft made up for it when the 528 went in. After adjusting the pinion angle the vibration has gone away.Dave

Ted; I still get laughed at unless they hear it running or see it make a pass. Dave

Dave, no one was laughing at the last cruise night you were at. In fact when you fired it up one guy had goose bumps on his arms.
