All 1978-86 trannies are aluminum and have a 8:31 R&P. I also have the 4-speed ratios, but I don't think you care about them. I have incomplete data on the subtypes (i.e. -12)... not enough worth posting.

How much torque do you think the engine will make, anyway? I'll be willing to bet that you'll have a tough time killing a 915, even a weak one :-). What cruising rpm do you want?

Take care,
