Hi Everyone,

I think this is going to annoy people as it is very childish but what can I do to my 1974 Oldsmobile Regency 455 4 door to make it do burnouts easily (without using foot brake)?

Is it a matter of changing diff gear and if so what effects would it have on driving the car, if this a silly idea please let me know if it would work out I would have to give up the driveability of the car.

By checking the VIN number, it apparently has the 250HP engine if that helps at all.

Any help is much appreciated.

Cheers

Or if anyone else can make another suggestion apart from Dif work, any advice is appreciated. Cheers

The VIN doesn't matter as only one engine was available for the 98 in 1973. It was a 275 hp version of the 455. It was also the standard and only engine offered in the Custom Cruiser.

Cheers any advice on sensible modification is much appreciated like suspension/sway bar bushes /diff etc

If you can find someone who can put a good power tune up (including the carburetor) on the engine plus find a higher numerical gear ratio rear end it should be able to do burnouts.

I'm not sure what rear end that would have but just for the sake of discussion a ratio of about 3.55:1 should let the torque multiply enough to do burnouts. Narrower tires (tyres?) and higher tire pressure would make it easier to spin those tires plus it is cheap. At the price of petrol in the UK it won't be a "cheap thrill" to drive the big Olds and do burnouts with any frequency. But hey, its also about fun.

As to the effect a higher ratio rear end would have on driving its going to be turning more rpm at every speed and its going to inhale gasoline like you can't believe. Burnouts obviously wear tires faster and subject mechanical parts to more stress thus more breakage than if driven sedately. A power tune up designed to get maximum performance from the engine is also going to be at the expense of burning more petrol. There is no way around that. With regard to narrower tires, they will lose traction easier when you mash the footfeed but there is also a safety issue to consider so be sure to look at the load carrying capacity of the tires. Narrower tires may not be able to carry the considerable weight of the big 98 Olds as safely as factory recommended size tires. Everything one does to modify a vehicle for more power is a trade off for efficiency and economy and maybe safety if not done correctly.

Also if you have to go through emissions testing a power tune up may cause the car to fail emissions tests.

Thank you for the advice, the more I ask about the car, the more I am realising it is just best to get it running stock and use it as it was designed to be used as a big comfy cruiser.

Petrol is a lot but I don't like soccer so need something to spend cash on and I can't think of anything better than turning it into tiny explosions which make a brilliant sound...

Just like with the Ford guys, just wait until after it rains.
