i have a question of how much a safe amount of boost stangs can push without blowing the block to hell. and it will be a built motor as well. because im planning on TTing my 03 gt and no one has given me a spot on answer. a good knowledgeable answer would be welcomed.

plus i heard you can direct swap a 5.4 into a 4.6 gt. also an answer for that will be well appreciated!!

What do u mean by built motor?

Stock block and stock rotating assembly... keep it at 400rw...about 9ish psi...

Stock block and forged rotating assembly... depends what ur set up is rated to... im looking at doing an mmr600 and running 14psi plus spray

As for the swap yes and no... it bolts in...need a new intake and some effort with the exhaust... over all id keep the 4.6 for various reasons

built bottom ends can handle 800rwhp+ depending on the parts used. The stock block is able to handle 1000hp and then its up to the internals on how much hp it handles. also, what heads are you using? 4v or 2v, either ported PI or TFS heads? I'd say TFS 2v heads ported with twins would be pretty f'in sweet!!!
