No way is a larger V8 fitting into a FWD car without EXTENSIVE modifications to the chassis. Some cars use smaller V8 like the Lincoln Town Car, Lincoln LS, some Cadillacs (with Northstars) but they're genrally less than 4 liters. The problem is the length. Mount a larger V8 in a FWD configuration and it's too long because of the extra 2 cylinders over a fitable V6. You could always convert the car to RWD which would require reworking the frame, modify the underside of the vehicle for a transmission tunnel and driveshaft, modifying the entire suspension so the front would work without CV joints and reworking the rear to accept a live axle (or IRS but that would be a total b!tch). Most of the FWD cars you see with V8s are either drag only cars with tube frame chassis or some show car that a shop put together over a few months to show off what they can do.
