[quote=spdbrake;1474094]The 427 that Roush makes is a stroked small block 351 based.
Their smallest and cheapest FE based (big block) is a 511 cu @ approx $29K US.

Personally I'd try sourcing the engine in-country. If there are warranty issues later (chances are there will be) you won't be stuck with freight to-from the US.
I didn't know the Roush 427 was also a stroked 351. Sooo much to learn here
I would love to source one locally however have not yet found anyone that offers such a thing. It seems to be very much an American thing !!
