Tremec or Getrag Box ?

[PeteT]

I am in the process of shopping for an engine. I have had my Dax chassis jigged up to fit a small block Chevy and Tremec box. I have just finished building and now have a rolling chassis which i am keen to put my engine in. Hoping to purchase a 350 Chevy around the 400 bhp mark, this will be linked to a Jag 3.31 powerlock diff. Although i had decided on a Tremec box, some one said to me why not use a Jag based Getrag box, (could save my self a bit of cash then).. Has anyone fitted this box, will it handle the horsepower?? or am i better sticking to the Tremec box ?? yr comments please

Cheers

The getrag was out of a BMW, and they never got anywhere near the 400lb/ft torque, which is what you need to measure it by, not the HP.

If you buy cheap, you pay twice.

Hope this helps.

On the contrary, I have a Getrag 5 sp. out of a Jag. XJS 3.6, sitting behind my 400 Chevy which was dynoed at 451bhp & 516lbft torque. It is a delight to use, smooth & precise, and no reliability problems so far at all. I change the gearbox oil once a year regardless of mileage. Therefore I can only recommend the Getrag based on my personal experiences.
Hope this helps you to make the best decision.
