Version 7.6 finally makes a couple of important updates for realism now that I know how to do them including the ability to coast/free roll without throttle, removal of ABS which should not be on a classic of this era to begin with, changed to a solid rear axle with no camber like the real car, fixed the stupid Rockstar wheelie update and I've also made major improvements to the general physics/handling behavior of the car.

I tried my best to make this car and Sam Mods Buick GSX handle very similar to each other because they are sister cars in real life and are built on the same body/frame platform. In real life and in my handling files the Buick drives much better because it has better suspension, factory disc brakes, a lighter engine and better aerodynamics. However the Chevelle has more HP and a lower gear. The lower gearing means the Chevelle actually has less top speed despite the extra power but that low gearing gives it brutal acceleration which makes it ideal for drag racing. In short, the LS6 454 Chevelle is best suited for drag racing and the Buick GSX is a more expensive, more refined version that does everything else slightly better including top speed.

As of version 7.4 1st gear length is fixed and wheel spin has been increased to a more realistic level, this means longer burnouts :)

Braking and cornering performance is even more realistic now, specifically the car is less likely to "oversteer" and more likely to "understeer" and brake pressure and bias have also been adjusted to more accurately mimic the cars true braking characteristics (bad brakes)

Version 1.5 changes the power level from crank horsepower to wheel horsepower, this means more accurate speeds and acceleration as well as a more realistic and more noticeable difference between automatic and manual transmissions.

1960's and 1970's American muscle cars were all about brute power and bold looks and the 1970 454 LS6 Chevelle SS was no exception. The car is powered by a monster 7.4 litre big block V8 that by itself weighs more than most motorcycles. The Chevy 454 big block produces such immense torque that less powerful versions than the LS6 were used in some GM buses and dump trucks.

We all know insurance for fast cars is expensive but during the muscle car era factory and super stock drag racing wins sold cars better than any commercial could. As a result manufacturers were producing over powered yet under rated engines made available directly to the public through various performance cars. It was a simple trick for the manufacturers to provide test results of their engines output at less than its peak RPM.

At a time when you could not afford to list your peak power and still sell the vehicle reasonably Chevrolet dared to advertise 450 horsepower, however it is common knowledge among old school muscle car guys that a 454 LS6 has over 500HP and excellent modification potential. This makes it a very sought after engine and relatively rare now that nearly 50 years have gone by. Obviously handling and cornering is not what this car does best. In fact it may be one of the worst handling two door performance cars of all time and this is mainly due to the engines weight. Just imagine trying to drive your car around with a Harley Davidson motorcycle strapped to the hood. The Chevelle's poor handling is compounded by very loose rear coil springs that are better suited for straight line weight transfer than high speed cornering. You can see the car behave this way as it "squats" lowering its rear end under hard acceleration in an effort to prevent the tires from spinning so badly. Despite poor traction and cornering abilities you should be able to out accelerate almost anything until the car reaches top speed which is relatively low for such a powerful car due to poor aerodynamics and low final drive ratio options. The low final drive ratios were purposely selected to aid acceleration at the cost of top speed because the car was being developed for quarter mile drag races and top speed numbers were not a concern.

I have included two different transmissions to choose from (4 speed manual and 3 speed auto) and two different damage levels (normal deformation and increased deformation) so that's four seperate handling files to choose from.

Not necessary but I recommend using the LeFix Speedometer and Inverse Power by IKT both available on this site.

I may update this handling over time as I learn more about the automotive physics of gtav
