Hello I am looking to purchase a Monte Carlo ss. I have heard and seen videos on converting FWD to RWD with these cars so it is something I am planning on doing in the near future. The issue I am having is which to choose from (2006 or 2004). I love the body style on the 04’ ss intimidator and if I were to get the car I want to swap out the engine, would it possible to fit the same engine from the 06’ (5.3L V8) and put it in the 04’ (3.6L V8)? If not then what is the best engine I could get to increase the hp of the car, or should I just get the 06’ and do the conversion?

You got a big bucket of cash (30,000 or more) just kicking around?
You got intense fab skills?
Got a nice fully equiped shop to work in?

If you do then anything is possible.

Are you using a transverse or longitudinal transmission?

How about a link to one of those conversion videos??

I can see no way of doing this that doesn't involve cutting out the entire floor pan of the car and placing a new fabricated frame with new front and rear suspension and floor back in place....it's a major job, much like building a ProTouring ride, a ProStreet or Drag car, or a dedicated road race piece, using something like either a Art Morrison chassis or fabricating your own.

The front suspension/ engine/ trans mounts in a cradle. Not sure what about the rear but it's the same as Impalas of the same generation... I would think building a frame that bolts into the cradle mounts, and then extend rearward would work... Completely custom, plus the needed tunnel mods.. A Crown Vic frame might be the best starting point...

Also those FWD V8's don't work very well in a RWD application. However a truck 5.3L is a $450 engine all day long


All things considered, Dale ran a G body Monte in the 1980s. You'll be farther ahead just paint/ decal a complete replica of one of them. You can LS swap them easy and make it pretty quick

This one was featured in Hot Rod way back in 1996.

https://www.hotrod.com/articles/42647-1995-chevrolet-monte-carlo-v8/

"The construction of the Monte Carlo Pro Street was no simple bolt-it-in-and-go operation. Moss and his band began with a production '95 Monte and immediately ripped the entire floorpan out of the car, replacing it with a '95 Camaro F-car floorpan. This required lengthening the Monte's wheelbase by 3 inches, while also spreading the Monte's ribcage by adding 4 inches to the track width.

The F-car floorpan also tucks the engine under the cowl for better weight distribution while utilizing '95 F-car upper and lower control arms, production rack-and-pinion steering and modified spindles mounting Wilwood calipers and Corvette 13-inch rotors. The front F-car framerails were adapted to the Monte's front fascia and radiator support, while a special 3x3x.083-inch frame section was constructed utilizing F-car suspension pickup points for the rear suspension. A single-hoop rollbar was also fabricated to reinforce the chassis and the B-pillar area."

I'm not going to deter you in the slightest - I love crap like this. But be advised, you need some tools and skills. This is not a 'do in the driveway' giddyup.

The drive train install will test you fab skills, but getting the interior/dash to work will test you patience, ability and pocket book. I would imagine that you will have a minimum of $1500 in materials to convert the chassis to accept a RWD drivetrain - now buy one with all of the suspension and steering goodies. I'm sure you could use a donor vehicle for most of the suspension and steering parts, but that's a bunch of used, and possibly worn out, components.

Good Luck - Jim

I don't want to discourage creativity either, but I think your estimate is off by a factor of ten. There have been a lot of these W-body cars converted to RWD racecars. Finding an old one of those as a starting point is likely a LOT less expensive and a whole lot safer than starting from scratch.

Here's another W-body RWD conversion.

I'm saying $1500 for steel to make the subframe/frame to mount the engine, trans, rear anf mount the body. Tubing is expensive, but $1000-1500 of tubing is a lot of tubing. He'll need the tools and skills to bend and weld it together, let alone a homemade jig to get the body on straight. Perhaps I'moff by some, but I wouldn't guess by double.

No matter,it would be a cool undertaking if he has some fab skills and tools to get it done. I agree that he'll be a factor of 10 to get a drivetrain in it that runs, moves and turns somewhat.

And the front and rear suspension
And the differential
And the brakes
And the different floor pan
And the different fuel system
And
And

The tubing is probably the smallest part of the total cost.

Find a rwd car with about the same body dimensions that has a light hit perferably to the trunk.

Cut the body up saving the steering shaft and leave the drivetrain in place.

Brace the monte body then completly cut out the floor. Drop the body over the rwd chassis.
Install your fenders and front clip to see if you will need to extend/shorten the frame.
Weld up body mounts.
Build a floor.

Thats the easy way.
