Best starting point for V8 swap

Thanks for all of the advice guys..It really made me do some thinking and more and more and more research....I think I got lucky however. I found a 360 that had already been rebuilt. Well I hope I got lucky as long as the guy was truthful.

77 360 block 30 over cast 340 intake, J heads with a little port and bowl work done. 340 cam, everything there except a carb and power steering bracket (even the a/c mounting brackets so I can put my rv2 compressor on it). About 8000 miles on the rebuild. With it a 727 Trans just rebuilt with about 1200 miles on it. The engine work was done at Beaty and Woods a very good shop in Toronto. Engine was in an older gentleman's 67 Charger but replaced with a correct 383. The exhaust manifolds are 98 dodge truck that I don't think will work in my Duster but I was thinking TTI's or Doug's unless a friend can find some 340 manifolds he thinks he still has. Ready to drop in my Duster (after I paint it blue) $2500.00

So now I just have to get together all the small little odds and ends and let the swapping begin. I still need a 7260 slip yoke for the 727 that ps bracket and maybe a ps pulley not sure if my pump and pulley on the slant will work. I'll have to get my drive shaft shortened again....fun fun fun....Now I can't wait till spring.

Thanks to all who replied.
