The exact torque readings you get from a 350 will depend on how it's built. The camshaft, compression, carburetion and exhaust systems greatly affect the torque and power curves from humble to astounding.

So a lot needs to be known about the engine in order to even get started on this path of discovery. There are several ways to go:

- If you're rebuilding a stock engine the power numbers are published by the factory and are available on the web.

- If you're building an engine around something that's reported in magazine articles or in popular books, these usually are accompanied by dynamometer tests which will give you a good idea of where your build lies.

- If you not building far from the engine's whose results were used to develop power formulas for the effects of different components, you can use on line power models. Some you pay for and are very comprehensive http://horsepowercalculators.net/hor...wer-calculator Others are pretty simple http://www.race-cars.net/calculators...alculator.html but need data like 1/4 mile acceleration times.

Or you can buy a copy of Desktop dyno which is also a comprehensive design tool http://www.proracingsim.com/desktopdyno.htm

- There are simple basic formulas good for some general estimating but certainly not specific.

If I'm reading into your question correctly and you're looking for torque specs for various engine bolts... http://www.348-409.com/torquesm.html

uummm......ya, Bogie I was completely lost about what you were talking about in your post until the bell went off in my head. I think what he is looking for is bolt tightening torques and not engine output torques as in horsepower/torque numbers.

My answer to him would have been to go buy a Chilton Manuel but I am sure he wouldn't have wanted to hear that. I love to read Bogie's post due to his knowledge and choice of resources so I wanted to let him know what the guy was looking for and he very well may throw you an answer about tightening bolts that you would have never known without reading his answer!
