I am in need of an engine swap on my 87 Regal Turbo. Instead of swapping to a V8 engine I want to somewhat keep the V6 spirit alive and attempt an LF3 or LF4 swap. The engine is out of a Cadillac with either turbo or twin turbo. I want to know what I need to do to make it fit in the engine bay. Any help will be greatly appreciated. If I posted this in the wrong area please excuse my ignorance.
