Thanks for the insights. I always wondered what would happen if I just upgrade the stock 235 cam slightly.
Like you said earlier - best to always check with somebody who ran the same setup.

I have always stayed below 3500rpm with original tranny and torque tube for the past 11 years and never had any desire to wind up these cast iron 4 main bearing blocks higher.
To me it's about keeping them on the road every day. I really enjoy the non-synchro double-clutch column shifting. Can't imagine driving without it.

With a slight cam upgrade I was hoping for better breathing and a cooler running engine, during long hot desert freeway trips in the summer.
But sounds like I should just stay stock.

What is the stock cam degree and lift with a late 235 and late 261 anyway...?
