Hi.

A MK1 ought to be a small block to remain 'in character' I guess. As for the trans in that car being up to the job, I would personally doubt it would stand up to many hard starts with sticky tyres. I could be wrong. You'd need to know more about the box really.

Good luck:thumbsup:

Have a Mk1 big block, can the Audi gearbox handle the torque output?

Whether the engine is a "big block" or not is not going to determine the answer. You need to know the engine's torque output to answer that question. To know that you need to know either its actual performance on a dynamometer, or to have some sense of the engine's "state of tune" i.e. compression ratio, carburetion, camshaft, etc. I would ask the seller more questions.

There are many "small block" GT40s (i.e. based on particular Ford engine families) with displacement in the 7 liter range and torque output that can destroy transaxles. Similarly, there are "big block" Ford engines that would not.

Of course, one way to think of this is what someone at Keith Craft said to me when I was making engine choice decisions "If you're worried about breaking your transaxle, maybe you just need to keep your foot out of it." :)
 
Thanks for the reply Mark. why don't more gt40s run the g50 or the Getrag box like the ultima? they are just about bullet proof. it makes it very hard to find the right second hand machine.

I chatted with the owner of the car at Stoneleigh and its a monster.

I think he said it has a 7.6 ltr Buick engine fitted.

Thanks

As the Buick has an Aluminium block its probably lighter than a Small Block Ford

Thanks

Only the original Buick 215 engine had a cast aluminium alloy cylinder block. All the larger engines (300 CI & upwards) were deep skirt cast iron. However this (Buick 455) was one of the first engines to use 'thin wall' casting technology was claimed to be 150 lbs than the equvalent Chevrolet engine

Pual,

Even if you find a car with 'basic' Ford 5Ltr, those engine's aren't expensive to tweak and find more power.

I think quite a lot of 40's have G50 boxes. Take your time in jumping in. The right car will come along that meets your priority list.

A 455 Buick, fully dressed with all ancilliaries, wheighs 770 lbs and gives 510 ft lbs torque in standard spec.
Should test your polar moment theories!

Just done a little research into the audi a 8 box that I fitted and it is used in the a 8 diesel which has up to 590 ft lb of tourque at the fly wheel. perhaps when looking at audi the a8 box is preferential for v 8 torque figures ,mine was 435 ft lb if I remember correctly
