914 V8's: What breaks first?, Drivetrain Options

[Dunc]

All you v8 conversion guys. I hear all sorts of opinions as to what breaks when you convert to v8 power. I would like some opinions:
1. Axles: I hear that these are the weakest link. Replacing them with 911 shafts seems to be the "fix"?
2. 901 transmissions. When they fail, what breaks? The case? Gears/shafts?
3. What level of hp/torque is the limit of a 901 setup.

Thanks.

Dunc,

Rennegade hybrids has some nice axles that use VW bus CV's and adapters. Much stronger. $700

For the time being you can just keep putting used axles in. Most of the time used axles are just worn from the beginning and pop from the extra stress. If you put new or rebuilt axles in you would probably not break one for years.

901 trani will be fine for a 307 or even a 302 as long as its a mild build.

Building a 302 would be a great match and something I had planned on doing myself.

If you keep the tires small and avoid doing burnouts and anything but driving up on a trailer in first then you'll be just fine.

Biggest issues with most SBC conversions is cooling. If you dont have a cooling system in there just spend the money and buy a Rennegade hybrids setup. It works, plain and simple.
