This is what I had done for my RF, which of course never came, thus the motor is going in the Lola. I think it capable of extended track work.

Now I fear after having a year of SCCA wheel to wheel racing and track work under my belt, I think the engine is too much. So, I might be detuning it for the Lola. I think around 350-400 tops would be great for a 2000lb, or less, Lola track toy or a GT40 weighing a little more. I went for high revving power and little torque, or as little as it'd make, so as to fit with the Audi/Getrag steep transaxle. If you are using a ZF you might not want that much high end power as the ZFs are lazy, or at least the ones I've driven in Panteras, fairly tall ratios. You might need the torque and mid-range power, especially if you plan your RF to be on the heavy side.
