the original motor is being saved and cleaned up but the point is that it's still an inline just a bit bigger. its the spirit of the thing. i don't want to add boost to the original motor and potentially destroy it.

 

There is a couple of problems with your plan. First off, If you build a motor to work well with a turbo then do not put a turbo on it, it will run like a worn out dog. It you build a motor to be fast without a turbo then add a turbo it will never work well. You would be luck to see even half the preformance you should see from a turbo.

Second is budget. Stock the 292 crank can not handle much over 300 HP. Like I said in the other post once you get up to 5K even under 300 hp in their stock form they can fail. The 292 are still popular with the truck guys but thats because of low end torque.

Those guys with big horse power motor have either a ton of money or a ton of time in those motors. Most High HP motors have billet cranks, billet main caps and custom machine block with webing support. They may say they only have a few K in them but thats because they are machine shops/engine builders. The blank to make the crank would cost $600 to $800 for the stock and about 40-50 hours to machine at $75 bucks an hour. It aint for the budget minded. Add in another 25 hours for the caps and 20 hours to work on the block itself and you start to see how one of these can get nuts fast. For a machinest its a fun hobbie for most of use the hours behind custom stuff puts it well out of reach.
The valve cover that you showed is needed due to increased valve lift. For a sheet metal fabricator its a weekend job but to pay to have it made I would bet thats an $800-$1000 part.

 

somewhere along the line you seem to have gotten the idea i was out for a ton of power that is not the case.
i have a plan. i know what it is going to take. like i said befor i will let the build show the results.
