Yes 65 Falc, all you have to do is use the two piece motor mount and it will drop right in.
The headers from Tubular are not the only ones that work but I have found that they are the best fit for the swap.
In 1998 I had a Boss 302 in my 65 with Tubular Auto headers and even with that combo I was pleased with the fit.
In fact even a 351-C will fit between the towers on a 64-65 Falcon!
But, it's so damn tight with the C engine I would not recommend it to anyone.
The 429-460 will fit the 64-65 Falc with the Crites tower mod kit but the firewall will have to be moved 5 inches back to clear the lenth of the engine.
Again, I would not go through all that for a swap.
But, the 351-W is absolutly a drop in affair and the engine will not be that hard to change plugs on.
So in closing 65 Falc, 351-W all the way!!!!!!!!!!!!!!!!!!!
