I think i am up and for my next selection i will fill the North American Category and select the Hemi Cuda.. i love the look of the car but the 426 hemi si what really made it.

The 426 Hemi also proved to be an immediate success in NHRA drag racing. Its large casting allowed the engine to be overbored and stroked to displacements unattainable in the other engines of the day. Top-fuel racing organizers still limit the bore spacing and other dimensions to the 1960s hemi size, making it the de facto engine template. Engines with larger dimensions, such as Ford's 385-series, are banned under these dimensional restrictions. In NHRA top fuel racing, the Hemi was usually equipped with a large Rootes type supercharger and short individual exhaust pipes, and fuelled with nitromethane.
The 426 Hemi, in "street Hemi" form, was produced for consumer automobiles from 1965 through 1971, and new crate engines and parts are available today from Chrysler. There were many differences between the Hemi and the Wedge-head big-block, including cross-bolted main bearing caps and a different head bolt pattern. There were also many differences between the racing hemis and the street hemi, including but not limited to compression ratio, camshaft, intake manifold, exhaust manifold and carburetion.
The street Hemi version was rated at 425 bhp (316.9 kW)(Gross) with two Carter AFB carburetors. In actual dynomometer testing, it produced 315 rear-wheel HP in purely stock form [1]. Interestingly, Chrysler's sales literature [2] published both Gross and Net HP ratings for 1971 (425 Gross HP and 350 Net HP.) Assuming a 15% driveline loss, the 350 Net HP figure (at the flywheel) equates quite well with the aforementioned 315 rear wheel HP figure. These power figures are further supported by plugging vintage 426 Hemi road test trap speed data into Hale's Trap Speed formula, which is: Peak Flywheel HP = (Trap Speed/234)^3] * Race Weight. While urban legend might have us believe otherwise, there is no objective evidence to support the notion that the 426 Hemi's advertised output was "under-rated" by Chrysler Corporation.
The engine could produce much higher HP figures with relatively few modifications, but those modifications drastically affected the engine's drivability on the street as they usually were made to take advantage of the free-breathing nature of the cylinder heads at high engine speeds.
To avoid confusion with earlier (1951-'58) and current Hemi engines, the 426-based Hemi is sometimes called the "2G" or "Gen 2" Hemi.[3] The easiest way to identify a 2G Hemi: A distributor at the front.
The street version of the 2G Hemi engine was used (optionally, in all but the last case) in the following vehicles:
