That's a sweet Mustang Phantasea427. Where is Mountain Dragway? I'm originally from Lousiville and was a spectator at Bowling Green and Ohio Valley quite a few times, never raced there.
Thanks again for the info!

How good is that Door Slammers book? I am looking for another chassis book more on performance instead of this little So Cal Speed Shop "How to build chassis" book since all it's on is old 30's Fords and to buy their parts.
If it worth the money or what? There are about 12 other books I am wanting to buy over this year and first starting with chassis and engines and paint since that is what I am doing and later I wan't more electrical books, etc.
I read some stuff yesterday that I thought said the right rear would try to twist off the ground on launch so extra weight may be needed on that side. Wouldn't jacking up the right rear take weight off? Of course who am I to question someone that's been racing. I need to get that chassis book!Quote:

Preload is where you "jack up" the passenger side anticipating that during launch, the car will be even. In your case, I think you can just leave it level. Extreme cases can be seen at the track where when you look at the car from the rear, the passenger side rear bumper is higher than the drivers side rear bumper. I use very little pre-load in my car. You will learn all this stuff when you read through "Door Slammers".
Good Luck!!
If this is the one, here's a link: Door Slammers - The Chassis Book Includes 1 book, 2 tapes, 1 audio CD - $99.95 ($10 off) + $4.95 shipping.
I just ordered it. I know I need it. I got on mine about 1/2 throttle the other day in front of the house and it got all kinds of sideways! Of course this street isn't all that smooth but it spun the 18" street tires like it was on ice.
MP Dragway is to the south east of Lexington. I sometimes race at Ohio Valley. Maybe we can hook up one day and go racing :-)Quote:

You got the correct book. I think I got mine from Summit about 10 years ago, I just have the book. I didn't know that they now have a video etc.........
The torque of the engine is trying to push the passenger side rear into the ground and trying to lift the drivers side. That's why some people will preload a chassis. I'm sure you will figure it out with some testing and tuning, that's the fun part :3dSMILE:

I think you'll find that the opposite is what's happening. A front-motor, rear-drive doorslammer will twist the chassis so that the left front and right rear get light, the right front and left rear get heavier. This is why you'll always see the right rear tire worn out on cars owned by stoplight wannabees that have an open (non-posi) differential.
Ever since I was a kid, we've been adding a leaf or two to the right rear on leaf spring cars or changing to a longer/stiffer spring on coil-equipped cars to preload the right rear and also to keep the left front down. It became easier with the advent of air shocks. You'd just bolt an air shock on the right rear only and adjust the pressure until you got two equal length black patches.

Yeah, what he said :HMMM: I got it backwards :LOL:
IT will be interesting to see how your truck reacts to a good set of slicks, a loose converter and a smaller pulley (more boost). Just remember that street and strip are two totally different worlds. I can pack the wheels pretty good at the strip but the street is much less forgiving and traction is limited.
Good Luck!
1---Line up at beginning of track
2----watch christmas tree
3---when light turns green mash accelerator pedal to floor
4---hang on for dear life
