That is why I think a 80/81 Trans Am, FireBird or Camaro would be a better choice since I will only run in Classic Category...  My search is for a Trans Am, I  think it has better front area than a Camaro.

I believe the Monza would be a  better choice and is more aero than any of those mentioned.

I had a Monza back in the day. The wing shape of the body made it lift but it was fast.

Maguromic,

I agree the Monza would be a bit better...  2 reasons it is not my first choice.

1. It is harder to find one in decent shape around here.
2. I am not sure I can fit in it.. I am 6ft, 370lbs,,,
    (not extremely flexible due to a M/C crash that broke 13 bones and a few pounds of stainless steel and titanium parts holding me together)

If I could find a Monza that has been drag raced and see if I can get in and out,m that would help make the final decision,, I know I can get in and out of the Trans Am   style bodies,,, (longer doors)

Cajun Kid,

You have to drive what makes you feel comfortable.  Your idea of trying a Monza is a  good idea.  Do any show up to Maxton or any of the other races in your neck of the woods.  Don't let you hight and weight hold you back.  I have seen several 6 foot close to or over 300 lbs guys in roadsters.

I completely understand what you mean by having metal holding you together. I am in the same boat.  I have so much metal I travel with a medical card, otherwise when all the alarms go off at the airport they take me to a private room for a search. :-o

At the airport... been there done that,, after 9/11 it made air travel for even worse, they don't except the medical card,,, I still get the wand, frisk and sometimes the private room,,, hmmm now one time at Miami Airport,, the busy line I got in was a blessing,,, the security agent was a 6ft. Tall Bodacious Blonde,, and the frisk was so good, I just about turned around to go back through the line again..  :evil:

Cajun, good job staying on topic....  :-D  Looks like you have built in ballast and a steering dampener....  :-D  :-D  :-D  :roll:

Am I on track?
Weight = good for starting line traction, may be needed for quite a while for same, but may interfere with stability (i.e., CG vs. CP) as speed gets well up. YRMV = given.

...

Does ballast have to be fixed in place, or merely "secure against loss"?

With the Stude we added about 1000 lbs. last year and went faster.  We are adding another 500# this year and Hooley, John, Patrick and Jerry just did that.  My theory is it isn't going to hurt us accelerating as right now we can only use 25-30% throttle in 1st and 2nd without spinning the tires and our first gear is a very high 1.90 with a 2.47 rear.  I'm hoping the extra weight will help us in 1st and 2nd with traction we need there and again at the top of 3rd and in 4th where we have had problems breaking the tires loose when we get to the "aero wall".

We need to accelerate faster to hopefully get our 2 1/4 speed up 8-10 mph if we are going to break 250, which is our goal.

Our added weight is going in to hopefully move the CG forward another couple inches and will only result in about 250 lbs. more on the rear as we have been keeping the car at a 50/50 balance, which in our case according to some crude calculations has kept the CG ahead of the CP by 6-8 inches.

I'm not sure if anyone has gone with movable weights that could move during a run.  I for sure would want to get a ruling in writing before I proceeded with that.  In our case I don't see how it could be done with all the other packaging requirements.  Also as I mentioned above you need the required weight on the back tires on both ends of the run, so I would think moving it forward for stability on the top end of the run would then get away from the weight you need at that point of the run for traction to overcome the aero drag, but I don't know for sure what you have in mind.

Keep us informed,

Sum

Mike,  I used 4" square1/4 wall tubing which I welded a section of 1/4' 4x3 angle  one before I filled with lead and one after and drilled a 1/2' hole for mounting to frame---I suggest you not make them over 100#---I made one for a specific place and it weighs 160# and it is a real bitch to deal with

this system makes it easy to relocatre the weight..
