Honestly it is all about what you need for performance.There is nothing like having a big block under the hood of a Cobra,if for no other reason than the visual impact.Big Cubes means big torque, easy horsepower.If you plan to road race then it's either small block or aluminum big block.You will be able to road race a big block car just have to watch out for the torque in turns kicking thew rear out.Either way have fun in your search.
