Anyone know if you can drop the 03/04 cobra (shortblock)4.6 in the newer 07 gt?
Will the newer 3v parts bolt onto the cobra short block?
If you can, is this a big hassle ? Well hopefully someone else is curious about this too. I would hate to spend alot of cash and get stuck.
Take care.

I believe the main difference is motor mounts. The heads should mate up NP, though you may have to use timing chain tensioners from a mix of years. Not sure about the front cover either.

Yes its possible you would needadaptors for the iron block, ? The 3v heads you can fit the block to im sure Most places that buildshortblocks use the iron cobra block over the aluminum.
