Will the 5.0 become obsolete

[Chevyguy]

The only issue that could have lead to the demise of the 5.0 would be if Ford stopped producing the blocks. The phase out of production installed 5.0's in 2001 could have lead to rumors that this was ultimately planned. But with the new aftermarket ( Dart?) pair of windsor blocks with either a 302 or 351 deck height ( or higher) avail this is no issue. Now it's possible to make a completely aftermarket 5.0 motor just like the Chevy guys have been able to do for years. Stock 5.0 blocks will still probably be made for years to come in Austraila similar to the Mexico made Chevy Goodwrench 350's that still have the 2 piece rear seal that GM redesigned back in 86.

This shoud ensure the long life of the 5.0 performance market for many years to come, regardless of what happens with the Modular motors.
