Nolando, I agree with Hank about the turbo engine instead of a Strong N/A engine. To build a 400 HP N/A engine for instance, can end up being more expensive to build than a turbo engine with 400 HP. Also, the 292 engine would be a real powerhouse to build with a turbo, but much more cost to build than a comparable 250 with a turbo of the same power output. There is a ton of off-the-shelf H-beam and I-beam aftermarket rods for the 250, but the 292 engine is a one-of-a-kind in that department, and at that HP level I would highly recommend it for either engine. Also as hank said, installing a 292 into a passenger car can be a challenge on several fronts, not only from the motor mounts, but also from the headers. 292's were only installed into pickup trucks, therefore headers for a passenger car might not always bolt-up good and provide clearances around the steering and other components because of the 292's much taller deck height. Its also a preference thing just like the straight shift, but do what your comfortable with.
