This beast of a 408 small block stroker is another variation of the many we build every year. Like all of the engines we build, it was built for strength so it will handle the power it makes, and the abuse it is going to be put through. The EFI system is yet another addition we can do to ANY engine is that's what you're looking for. An engine like this can make an EASY 450 - 500 HP depending on the head & cam combination. This one was built to make in the 500 HP area, and it'll do that pretty conservatively!
This particular 408 has a light weight 4340 forged crank, 4340 H-beam rods, light weight forged JE pistons, Total Seal Plasma Moly rings, Clevite H series bearings, a billet roller cam, ARP studs with a billet main support, a double roller timing assembly, a fully balanced rotating asembly, light weight (transfer bar) roller lifters, fully CNC'd AFR heads, Chrome moly push rods, Harland Sharp roller rockers, a port matched intake manifold, MSD billet distributor, etc, etc. Something like this can easily run in the $13,000 - $14,000 area because of the EFI system. Remove the EFI and go with a good carburetor and you just shaved-off $3,000 or so.
As will ALL of the engines we build, this one was custom built to the customer's needs, which is why it does not have an oil pan on it. He wanted to put his own pan on it.
As always, we start with a really good block core and fully machine it, including hot tanking, shot peenining, bore, align hone, torque plate hone, and squaring the decks. Once that is done we chase all o fthe threads, wash it and paint it.
This particular 408 (like most of the one's we build) got some really nice components such as these super strong 4.250" 4340 H-beam rods with forged light weight JE pistons and Total Seal Plasma Moly rings.
Like all of the 408's we build, this one is studded with special ARP main studs to add strength and to accomodate one of our billet main supports. You can see the nice, lightweight 4340 forged crank and the beautiful nitriding it has which gives it that nice grey color. It's a super strong crank, and once it is in the engine secured with a billet main support, it becomes a super strong package that is 300% stronger than it originally was.
This is what the bottom-end looks like when it's all put together and ready for the oil pan to go on. You can see the nice crank, rods, etc all tucked-in under the billet main support. The double roller timing assembly, billet roller cam and new timing cover are all in place too.
This is the little car this monster 408 went into. Check it out in our "Other Vehicles" gallery.
