Hello All;
Speaking of dropping a 360 engine into an 81-83' Imperial, has anyone ever
tried to rig up a 360 with the EFI equipment out of one of these cars? If
one wanted to do this what would be the obstacles?
As someone mentioned before 135 horsepower is somewhat lackluster
considering the weight of these cars.
Could one improve the 318's performance, and still use the EFI system, by
using the heads off of a 340? Could one do something similar by using
higher compression 318 heads, either older ones or after market performance?
I don't own one of these cars but this thread has brought some ides to mind.
Best Regards
