Modular 5.0L. Now you can install a Ford Racing Boss Modular 5.0L Engine Block in your very own SN95 Mustang on the cheap. This block reuses everything from your stock GT's 4.6L V8, all you need to supply is a new set of larger pistons and brand new 5.0 is complete.

Built Ford Tough. This Boss 5.0 iron block features a 4.6L deck height and a 94mm cylinder bore. It is cast in Ford's Cleveland plant using a proprietary iron mix to yield the strongest casting possible.

Additional Features. Featuring a Siamese 94mm Bore and a 4 Bolt Main with interference fit nodular iron machined caps, this Ford Racing Modular 5.0L block has increased main web window size for less oil movement and greater power.

Application. This Ford Racing Boss Modular 5.0L Engine Block is designed to be direct fit replacement for the stock 4.6L block of the 1996 to 2004 GT Mustang.

Technical Note. This is a bare block, no internals are included. This block does not have a finished milled head deck or cylinder bores. Your engine builder will need to mill the deck and finish bore, then hone each bore specifically for the combination being installed.

If shipping to a business, please include the business name. Also, after your order is placed, be prepared to let us know if you will need a Lift-Gate service. You will be contacted via email before your order ships.

It says that this block needs larger pistons. Do I need 5.0L pistons?

sm34947

  • Yes, larger size 5.0l pistons specific for the modular 302 engines would be needed. This block is bare and only has a rough bore in it, so a .020-.030 " larger piston would be required in conjunction with custom machining to ensure a proper installation with this engine.

I'm currently rebuilding my Mach 1. I was going to get my heads block machined for new forged rods, pistons valve train etc... If I decided to use this block can I keep my machs 8 bolt crank? Can I keep my oem cams as well?

MachJuan

  • This Ford Performance Boss Modular 5.0L Engine Block would use all the same parts on your existing 4.6L block. So you should be able to keep your existing crankshaft and camshafts.

Application. This Ford Racing Boss Modular 5.0L Engine Block is designed to be direct fit replacement for the stock 4.6L block of the 1996 to 2004 GT Mustang. So from this description this block will bolt directly into a 4.6 engine bay? No trans mods or engine mount mods?

Bigdiezel79

  • The Ford Performance Boss Modular 5.0L Engine Block will bolt right up to your transmission without any modifications. You will be able to reuse your bell housing as well. You will not need to move or do any modifications to the engine mounts. This Block will bolt perfectly fine to their factory locations.

I have a 95 Mustang that I'm looking to rebuild this winter. Ultimately I'd like it to be supercharged once I'm done. 1) would this motor fit in my car or would I need to do some fabrication? 2) Will this motor be able to hold up with a supercharger on it?

MarkC

  • This Ford Racing Boss Modular 5.0L Engine Block is designed to be direct fit replacement for the stock 4.6L block of the 1996 to 2004 GT Mustang and would need a little work to fit in the 95 models. This block would also support a supercharger no problem!

Would this work with tork tech supercharger kit

JoyceneS

  • The Ford Performance Boss Modular 5.0L Engine Block is based on the 4.6 Block, and should not have any issues working with a Tork Tech Supercharger Kit.

Hey American muscle just curious I have a 04 mustang GT 4.6 2v.....is the motor a 5.0 2v are 5.0 4v

JoyceneS

  • The Ford Performance Boss Modular 5.0L Engine Block is just the engine block, and will not be a complete engine. This can be used with 4.6L 2v, 3v, or 4v cylinder heads.
