^ yeah, ya can buy an 5.0 aftermarket block, build the f*k out of it and still only pay half the price of what a 4.6 would take to half the power, sure the 4.6 block may be able to handle alot more power but to do that you still have to buy all the forged internal for ir to even make that power safely, so all in all i would rather buy an aftermarket 5.0 block and build it and have more power for half the price, but in reality if i was going to buy an aftermarket block i would the 351 block and make that thing a f*in beast
