yeah thats all i planned on using was the block but with all different internals and head work. so should i stick with that but all different internals?

Soaring:
The 4.6 and the 5.4 are basically the same engine.  The 4.6 already has most of the parts you are going to need to upgrade and will cost you a lot less in the long run, so if you want to upgrade, the 4.6 will cost you less for basically the same power. 

98gtstang:
yeah the 5.4 is pretty much a stroked 4.6    4.6 has 225 hp and 275 lb-tq.  the 5.4 has 300 hp and 365 lb-tq. so if i were to stroke a 4.6 it would pretty much be a 5.4    so i figured id put diffterent rods, crank, and pistons in the 5.4 block to make it bigger and make more hp and tq

Soaring:
It all depends on how deep your pockets are.  My 4.6 came from the factory with 300 HP. 

98gtstang:
yeah mines a 98 with 225 hp.   yours is a 99 or up i bet with the 300 hp
