Hi there, just need to know what's needed for an L27 to an L67 swap. I have the capital I just need a list of things needed for this project. Any help is much appreciated.

This sounds very interesting as I would like to do this to a 92 Regal Coupe.

Yeah I got this Buick in an estate sale she only has 32,000 original miles and the paint is perfect not a dent or rust on this thing. That's why I want to make her my project

As far as a parts list goes, you would at least want a W-body donor. Having never done the W-body swap, I can't specifically say, but in theory the whole thing should drop out of the donor and into yours.

-Engine
-Harness
-Trans
-Axles

Then there are the main things that slow a swap down, where you'll either have to make adapters or find new parts to make everything work, but sometimes they bolt right in.
-motor mounts
-wire harness adapter (best bet is to have both CSM's and knowledge of basic DC circuits and be handy with solder).
-A/C
-Power steering lines
-heater hoses
-throttle cable
-cruise control
-intake and filter
-exhaust downpipe

A lot of it is tinkering with motor mounts and brackets trying to piece together something that fits. I think you having a L27 car is going to help out because you should have all the brackets and things like that that will fit already. The hardest part is the wiring. You have to adapt the new harness to fit the car. I always make a pass-though adapter with parts from junkyard cars, leaving the main harnesses unmolested, in case anything goes wrong I know where to look.

Your fuel pump will work fine as long as it's not worn out and you don't plan to do any mods. But I would recommend pulling the fuel pump from the donor as well, though you might have to use the donor sending unit too if the fuel pump is a completely different size.
