340 Manifolds on 318

nice write up, but what car is this on? i swapped /6 out for a 360 and would like to know if any of this will work on a 66 Barracuda. Especially that driverside rear dump 340 man. i see YearOne has the 1968-1970 A-body manifolds are these the same as the ones on this thread?

Casting numbers are 2863553 (left hand) & 2863549 (right hand).
