Woodfin's SS GT/TB construction series

In ref to the thoughts about weight bias. The height of the cab is a big factor in weight transfer because the center of gravity is higher than a car body. Plus, the driver sits higher than in a car.

Now that we have a 408 SBC w/aluminum heads of 700 horse the Super 10 leaves the line with a wheelie that is way up there. I have a video of the tail lights reflection off the track surface.

With each outing, I am making small adjustments to keep it under control.

Larry,
I may have missed it , but curious on how much weight you had to add.
Ours is not going to have that much power for the first few years.
Probably only around 500 to start but we want it to be as consistent as possible in the first 60'.

We didn't add any weight to my son's 97. 59/41 front to back. Added about 80 in the bed and didn't make any difference so we took it back out. Our 4 link is close to your setup, Larry. Yours is a little farther out and lower than his. When we put the 31" tire on, I'll have to reset everything and should ended very close to yours, then. Thanks for your responses.

Duke,
How much power are you making and what kind of 60' times?
We have two cars with ladder bars that run in the mid tens to low 11's.
so this 4 link deal is all new to us.
Also wondering how muck preload people are running with these trucks with 4 links? Larry what are your thoughts?

Like is posted above, I experimented with weight in the rear but it did not change the chassis action for any detectable amount so I removed it all.

In the rear of the bed is a K & R air compressor, 5 gal cell that usually has 3.5 gals, and a 16-volt battery.

The Super 10 weighs 2760 less driver.

Aluminum head small block, fiberglass hood, gutted doors, one factory seat, aluminum custom dash.

It has run as fast as 6.03 in present trim.

speaking of pre-load. My experience shows that when coupled with an anti-roll bar [which I highly recommend] only a very small amount,if any, pre-load is required.

When working with chassis adjustments be sure to move in very small amounts. 1/2 flat on a four-link bar is enough to show a change.

And speaking of scales [and this is personal form my experience and may not reflect the experience of others] I have experimented with scale adjustments but the car/truck will show you what it wants.

The last adjustments I make on a new package before going to the track is on the chassis table with driver or driver weight in the seat. I will adjust 1/2 flat in the right upper bar[with anti-roll bar disconnected] the just take the slack out of the anti-roll bar links [turning the links in the direction to make them longer]
