Here are some more information for Block Billet Aluminum:

Drag racing is a fast and furious sport. Thousands of horsepower are unleashed in the blink of an eye and have to be harnessed safely down the track in a matter of few seconds. In comparison, an average road car might have one or two hundred horsepower and take about 20 seconds to cover that distance. Needless to say, it takes some clever engineering and manufacturing technology to achieve a reliably performing drag racing car.

Drag racer Paul Carey of AERO Racing drives a Mazda RX-7 in the 'Supercharged Outlaw' class of ANDRA's National Drag racing series. The AERO Racing team have been using an advanced quad-cam Toyota V8 engine to power the RX-7 down the 400m drag strip. Not only has this given them a point of interest, as it is unique to have a Toyota V8 among the legions of American V8's, but also enables them to be running sub 8 second 400m times.

During the 2008 season, reliability problems with the engine were not letting Paul and his team achieve the best performance from the car. The extreme pressures from the big PSI supercharger were frequently splitting cylinder bores in the steel block, leading to expensive and time consuming engine rebuilds - not to mention the loss of points in the competitive series.

The solution was to develop a completely new engine block from a billet of Alumec 89 which could withstand the rigors of competition. But without starting from scratch and re-inventing the wheel, or engine even. The next best thing was to manufacture a better version of the standard block, stronger and more durable and at the same time retain the ancillary systems that were already developed for it, such as the PSI blower, heads, camshafts and bell housings. One of the aspects to improve on was to remove un-necessary water coolant passageways in the block, which are not required when runs are typically less than 10 seconds and using Methanol fuel.

The need for some reverse engineering was obviously there. Reverse engineering is a process where a physical part or complex shape is digitised to create a CAD (Computer Aided Design) model on sophisticated computer software. Ultimately using this CAD model to re-engineer, update or add to the original design.

Other uses of reverse engineering are in cases where the CAD models or manufacturing drawings for the original parts may not exist and need to be re-created, such as re-creating parts for historic cars or machinery or additional parts to accurately interface to existing parts. All the automotive manufacturers and even top motorsport teams utilise such technology to speed up the design process.

There are several ways to reverse engineer a part, including measuring it with a ruler by hand. But more sophisticated methods are available; these are called CMM, (Coordinate Measuring Machines). More specifically a portable CMM, which is in essence an articulated arm with a probe, was required in the case of the engine block. A high precision rotary encoder (a high precision position sensor) for all 6 or 7 axis enables the part to be measured to an accuracy of within 0.02mm. You can measure any point on the part in full three dimensions (X, Y and Z) by simply touching the probe to it. Otherwise laser scanning attachments are available which enable the full three dimensional surface to be digitised. This is more useful for non geometric shapes and contours like the dashboard of a car for example.

In all cases, an experienced technician is needed to operate such a high precision machine, as even the movement of an operators breathing can give vastly varying results. There are techniques to help against this happening, such as taking more data points and averaging the results.

A full survey of the existing engine block's features was performed and then used to produce an initial CAD model or point cloud model. The tool enables the user to create surfaces, circles, points and lines in the 3D model representing the real part's surfaces, cylinder bores and bolt holes. Generally this won't be ready to send to the machinist straight away as a whole host of post-processing is required to create a finished CAD model. This is where an experienced engineer is required to take the measured features and produce a finished solid model with all the dimensions accurately specified and tolerances set out. This whole process requires a large degree of precision and attention to detail to maintain the critical geometric tolerances required by this 1500 HP engine.

The model can then be passed on to the machine shop for manufacture. High precision machining is another article in itself, but needless to say CNC (Computer Numerically Controlled) machines are used across all manufacturing industries to produce components of very high accuracy, complimenting the accuracy of the CMM quite nicely.

The finished product is identical to the CAD model produced by the reverse engineering process. The block is made stronger and able to withstand larger cylinder pressures and temperatures with reduced warping. Remember this engine produces 1500 Hp from 282 cubic inches capacity! All the ancillary devices like the PSI supercharger, cylinder heads and gearbox bolt back on as per the original engine. Reliability has also been improved and with that the elapsed times have fallen to a personal best of 7.367 sec, all thanks to some clever engineering.

You have always noticed while driving on highways when a car from the opposite side is coming and passes you in a great speed. What is the first thing you notice on that car? It is the look of the car from the front side and what enhance it are the grilles mounted on it. Similarly, Ford F150 is a big vehicle and that’s why it is called a truck. F150 grilles not just give a different look but it gives a striking and stunning look to it. Grille is an important part of a vehicle. It serves some particular purpose. Ford F150 grilles not only provide a great look but also allow the air to pass properly through it, which is important for any vehicle. It is an important part. Think that Ford F150 grilles are important for vehicle and it gives a perfect look too. What a perfect match? This is called engineering.

Will this car pass emissions in CA?

passing smog in california ??? with the changes made to it -
-not a chance ! i have a smog shop i deal with everyday and there is no way it will pass like that. now you could do some creative bribery to get it done but, its hard to find people to "play ball" if you know what i mean . sounds like a nice car but the 76 's were not the cool novas of the past. still a nova yes but, a 76 and a SMOGABLE ONE AT THAT. think about it before you get stuck with it and cant drive it . do some checking in the smog thing before you buy it.
the 305 is no hot rod. and all the bolt on goodies may sound good but, i doubt that will do what you think it will . lots of cool stuff --sure but its 305 cubic inches and did the guy up the comppression for all this stuff ? cause if he didn't, the 650 carb alone will kill the chances of you getting it smogged right off the bat. then you have the cam to worry about too. non of this stuff is able to pass. do some long hard thinking before you spend your money.

Mustang adds muscle
The 2011 Mustang is bulked up on the outside and under the hood, giving it a ride that is more powerful but less easy-going than last year’s model. It is available at Cam Clark Ford in the Northshore Auto Mall.
