318 swap to 440

[280bb0]

I have a 72 hardtop with a 318 would like to drop in a 440 , other than the trans needing to be changed what wiring issues will i face. the rear end is a 8 3/4  will the drive shaft need to be changed and is the frame strong enough for the 440 or is it the same frame for a 318 and 440

if the 318 has a 727 trans the drivshft wil be the same length & will fit the big block trans
if the 318 has the 904 trans the driveshaft will be approx 4" too long & will use a different slip yolk
the 318 & 440 use the same K frame , you will need the bick block mounts though
you will need all the accessory brakets for the big block & a larger Rad to cool the big block
some wiring like the coil & dist wiring will need ot be extended to reach the front of the engine
