5.4 swap

<< < (2/4) > >>

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?

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. 

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

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

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