First off, welcome to the site, cool to have another 1966 Valiant! Where do you live? I am in St. Cloud, MN. What are you intentions for this car, a driver, drag race, stock? Did your car have a slant six originally? If so you will need to change the center steering "drop" link to one from a V-8 car. Your motor mounts need to be for an early 66-66 a-body V-8 car, you can also get ones for a "slant six to V-8 conversion" from Shumacher Creative Industries. (I got mine there, worked awesome!) 273 and 318 had a different driverside motor mount than the 340 and 360. The oil pan is easy, just need one from a car. Was your car an automatic or manual transmission? Any 904 trans will fit real nice, a A727 will also fit but you may need to modify some linkages to work. The auto trans just needs to be from a car or 2-wheel drive truck. Do you have a rear trans cross member? 1963-1966 a-body cars all had the same rear crossmember for all the different trans, just need a new rubber mount. The A833 4-speed will work but it needs to be from an a-body, ones from 1966 to 1976 will bolt right in. Any 273, 318 (post-1966 318), 340, 360 will fit in your car. The K-frame will also work with these engines. Keith. 8)

Keith pretty well covered everything. Just thought I'd add if you want to run an automatic unless it is going to be a real high HP race car running slicks you don't need a 727. The 904 will do you just fine and fits much better in an early A body. Just install a Trans-go TF-1 or TF-2 shift kit in it and tear up the road.
ok first thnaks for all your help i will have a ton more questions but first will a early 70's 383 fit in the 66 valiant ?..i have those motor mouts by schumacher for 273,318,340,360...if i have to buy new mounts for a 383 thats fine..but i am pretty sure the k member(?) in my car is for a 6 cylinder..thats what the vin number tells me..if that makes sense...thanks for any help
