I have a 1976 malibu with 56% front weight and total of 3560 lbs. Obviously this is way wrong and I need to know how to get more weight off the front. The weight rule is 3500 lbs. So far I have removed the inner fenders and gutted the hood. The bumper reinforcement is also gone. I plan on removing the power bake booster the bumper shocks and everything from the doors but the skins and possibly the radiator support if I can fab a lighter on. Any other suggestions would be greatly appreciated.

Sorry this is so long. Thanks in advance for the help.

If you haven't already, make sure you torch out the door hinge plates in the door post area. Or if the rules will let you, get rid of the entire doorpost/kickpanel.

get rid of all the firewall you can.I sold my old 77 monte to a guy who cut 200 lbs out just by doing that. Also on radiator support, first if it is not gone, remove the entire stock support and build one out of square tubing. Let the radiator set on the tubing with innertube pieces to protect it.

Well, you've got the right idea; just about everything that is not essential needs to come off. It is very important to get the car lighter than the weight minimum rule for a few reasons. One, it will allow you to add ballast where it's needed to achieve the correct percentages. On a car that needs to be so heavy like yours (3500#), don't be afraid to lighten it up to around 3200# so you'll have to add alot of ballast and you can get it just in front of the rear axle, if you can. What you can remove will also depend on your rules. If you can remove the radiator core support and the metal between the firewall and what would be the dash, do it. Also, If you can run an aluminum water pump and intake manifold, even a factory one, you have to do it. The cast iron stuff weighs a ton and they're right up front.

Thanks alot for the help. Range I have to run the cast iron manifolds and intake per the rules. Thank goodness I have plenty of time before the first practice. Looks like I'll need it.

I am in the same boat that Oscar is in. I have gutted the front end and am afraid that when the car goes back to the scales it will still be front heavy. I was thinking that it might be better to add ballast to the rear just to get the proper balance for the car. I am not wild about adding weight to the car anywhere but I figured the benefits of having a balanced car would be better than running one nose heavy. What do you guy`s think?

Even if you are gonna be heavy it helps to have the right weight %'s. I raced a 77 olds cutlass 4 dr. with terrible %'s. I already weighed 3780 but folks kept telling me to put some rear weight in. I was always losing ground on the sloppy heats and running good come feature time. I added 100lbs to the rear and man did it help the sloppy traction. I couldn't hull much anything at all do to the rules and we had a 3400 lb minimum so this hurt me. Add the rear weight and try it, sure helped me.

Unless you have **** Tracy for a tech guy, a stock aluminum intake if painted black or chevy orange is very easy to get away with. Also, If you are allowed to run an aftermarket nosepiece you might be able to get rid of that heavy front bumper and just use some sort of tubing set up.

poboy, Do you run the aluminum intake? I have wanted to do this but I hear that they warp very easy. Any truth to this? What about running it at 230 degrees, sometimes I would get that hot(400 with stock old wore out 4 core, with several rows missing due to hasty repairs) Thanks for the help

There are no problems with an aluminum manifold and overheating. If you got hot enough to hurt it, you would have much more sereous problems to worry about. We paint our aluminum Z-28 intake with a "cast iron look" rattle can from Pep Boys and it immediately looks 30lbs heavier. We also do the aluminum water pump. Aluminum stuff IS legal in my class, but I like to throw off the Looky-Loos. It's very convincing, try it. Oh yeah, do what you can to get a better radiator; it will be much cheaper than the potential engine damage. You know that.

for that extra heavy and woren out look, spray your intake with some wd-40 just before your warm ups. Itll make your engine look like a junk yard special. It washes/wipes off real easy
There are 100's of things to make your super stock engine look not so super.Ive painted bilit aluminum parts with paint just to make it look "slower".
Get creative.

around the track we run they stick a magnet to anything that could mabey not be cast iron. I have gotten away with putting grinding shavins in the paint, will help a little with the magnet, mabey enough to pass.

As long as that aluminum intake looks almost like a stock one,you mite get away with it,but all the techman really needs to check it is a magnet,I ain't never seen an aluminum magnet!!!

one way to take some weight off your car is find some ford fairmont bumpers as they are aluminum and fit nicely and take every piece of metal off under the roof and hood and trunk you can shave 50 pounds off easy oldgold
