no such animal,,,quit making Chevelles (A body) in 77 I believe, then it was just a Malibu,G-body, whole new deal. Todd races his at 3500+ I believe w/driver, correct me if I'm wrong.

Re: 1978 Chevelle weight

Yes, it is one of the small ones........looking at one that has been back halved with a 9 inch ford and room for 12.5 X 31 tires.

Could be a good "beater" race car if the weight can be gotten down a bit.

3500 seems heavy

Re: 1978 Chevelle weight

Bob's right. My malibu is a 79 and is all steel except for the fiberglass hinged hood and a fiberglass front bumper. I have all the undercoating removed, no sound deadener, no heater or A/C, no back seat, crash bars removed from the doors. The car has a 12 gallon cell in place of the stock tank, aluminum radiator, aluminum intake and water pump, 10 point mild steel cage, two plastic racing seats, stock dash & steering column. The weight as it sits is 3515 lbs with the iron headed bbc/th400.

IMO, the only way to get a bbc in a Malibu down to 300 lbs is with a fiberglass front end, doors, trunk lid, lexan window, aluminum heads, light weight brakes front and rear, likely R&P steering in place of the cast iron manual steering box, etc.

A back half car will weigh less than a small tire car like mine, but your removing weight in the wrong place. I was speaking with a friend at US13 who races a back halved Malibu and his has 60% of the weight on the nose compared to 55% on mine. If your gonna take weight out, it needs to come out of the front, not the rear.

So while you may think 3500 lbs sounds heavy, it's what a full steel bodied Malibu weighs with an all iron bbc under the hood.

Re: 1978 Chevelle weight

Yes, that's race weight with me (200 lbs) and a 12 gallon cell full. I only tend to discuss race weight as the classes I run require us to drive across the scales after every pass which is a race weight with driver & fuel.

Re: 1978 Chevelle weight

BTW, for anyone who is interested in the 78-81+ Malibu's as well as other A/G-bodies, an excellent online resource is my friend Phillip Patterson's site.

http://www.maliburacing.com

BTW, Bob, just for reference, the 78-81 Malibu is labeled an A-body by GM. The G-body name started in 1982 and continued to 1988 when they were stopped. The 78-81 was the only years the 2 door coupes were produced. After that you could only get the 4 doors and wagons.

Re: 1978 Chevelle weight

Thanks for all the great info. Looks like I can save at least 250 pounds over my 66 Beaumont.

I wanted to get a car that was more of a race car that I could beat on a lot and not worry about it.

Just wondering what kind of engine combo and converter you got to run the kind of ET's in your signature. Awesome fast. Are you using a tranny brake as well ?

Basic 13 to 1 compression oval port 454. Trans is a th400 with an 8" ATI Treemaster converter. Footbrake launched from anywhere from 1800 to 3000 rpm.

Re: 1978 Chevelle weight

Don't think there is such a thing as a "basic 13:1 engine".

How many rpms through the gears and traps ?

Re: 1978 Chevelle weight

Thanks for the explanation.

An awesome combination, very stout.

Fantastic picture of the car launching with the wheels high in the air.

Todd,

Your car STILL just amazes me on how good it runs!

Nothing exotic. Nothing fancy. Just awsome.

Re: 1978 Chevelle weight

it's almost what you'd call perfection of a combo. although there's nothing exotic about it, the suspension, the convertor, and the tune-up are all much better matched than most people ever take the time to get to.

Re: 1978 Chevelle weight

I looked at one of these Malibus recently and noticed that the frame is much narrower than the older Noves and Camaros in the engine compartment. It seems that getting good headers to fit in there would be difficult. I still like the body style of the 78-80 Malibus though.
