Question
Power capabilities
Hi there. The engine will not start to break down or lose power at that point. The factory engine does not make that much power on its own so I have to assume you are talking about aftermarket power modifications....
Question
I have a MB WDB2011281F343389-0 and I know it: It would be advantageous to place an intercooler and how to get a design for this?

Question
Will a after market performance chip increase my horse power? Will it pass smog?

Question
Engine modification
Sounds like a nice build. Assuming you used the 305 crank, the engine will still be called a 5.0 or 305, since that is the cubic inch displacement of the engine.
Question
What's the difference between a racing crankshaft and a stock one?
Most of the time it is unnecessary to use a racing crank in a street motor, unless you are planning on building a 700HP+ motor. The racing cranks are stronger, better balanced, more aerodynamic, and also much more expensive. Most...

Outside of an engine rebuild, what can I do to get high-end horsepower rather than the low-end torque inherent with american cars?

Turbo blow off valve
