06 mustang what blocks will fit?
so i am a old mustang guy last 1 i had was a 69 so i bought a 06 gt with the 4.6 and it runs strong but, i was wondering if the block is interchangeable with the larger small blocks. if the 3 valve ohc heads and intake would bolt on anything else or if you want to hop up a new stang do you just buy a new motor? i am truly clueless. thanks..
