: Also the transmission cross-member mounts will have to be moved on a 1969 1/2. It is different.

: : If it's a manual transmission, you HAVE to use a V-8 Z-bar. If it's an automatic, the 6-cyl. C-4 is weaker than the ones used with the V-8. You also need the V-8 crossmember, a 3-row radiator is a real good idea, V-8 motor-mounts, etc. Definately use V-8 front springs as you mentioned (unless it's strictly a drag-race car in which case the 6-cyl. springs are best). If the car has a 7.5-inch rearend ('69.5 & '70), the V-8 will shred it to pieces...
