Indy Cylinder Head/Milodon-Buildup - Pump Gas Thumper

Don't build another wedge or Hemi without this gem. This is a billet rear main seal retainer from Indy, made on a CNC machine.

It has exact dimensions to clamp the seal properly and uses two O-rings on each side for end seals instead of paper ones.

Naturally, a Milodon 30930 street/strip oil pan, their big stroke windage tray, high-volume oil pump with pump cover, static pickup, and adjustable relief valve ensure reliable lubrication. We cannot over emphasize the importance of a good oiling system-particularly in a high-horsepower application such as this.

When you use a big stroke, you can't use the internal pickup anymore as space is limited, so an external system is needed. Everyone thinks of a full race system when you say that, but this is a nice little package. The external system comes out the side of the pump cover instead of the back. You just loop the line around the K frame, and you can still use motor mounts. It's so simple.

Ross forged pistons were chosen for their light weight, strength, and quality. This setup used the manufacturer recommended street clearances, a 4.380 bore, 1.460 compression height, .990-inch wrist pin, and a 40cc dish. The Crower rods are 4340 steel, 7.00-inches center to center, and will take nearly any punishment thrown their way. Rods are one area where you do not want to skimp.

One look at the big 40cc dish and you'd think it's too much, and better for a blower or turbo application. But this is a big engine, and we only wanted a 9.5:1 compression ratio.

Piston volume was checked to ensure that we had done our homework right. Since this engine will be fed a steady diet of sub-par California unleaded fuel, the compression ratio was kept on the low side, squeezing a 9.5:1 ratio.

Indy 440-4 S/R roller rockers are 1.5 ratio, come with side spacers, and they work with 440-14 chrome rocker shafts.

This is a very strong system and is capped off by 440-11 rocker studs, nuts, washers, and 440-5C billet hold-down clamps.

Now the short-block is ready to receive the heads. The cast valley plate seals to the cylinder heads and block with silicone, and uses paper gaskets between the intake and head ports-no more tin valley pans.

This is the Accel/DFI GenVII fuel injection kit with the ECU, wire harness, fuel injectors, and all of the necessary sensors. The most important part is the dual sync distributor, which acts as a crank and cam sensor; normally not found on your old 440.

The Indy 440-2 intake can be bought EFI ready, which is machined for injectors and fuel rails installed. Here you see it completely outfitted with a 1,000-cfm air valve (throttle body), 36-pound injectors, a rail-mounted pressure regular, and fully plumbed.

To top the whole thing off, this is the 440-7 logo valve cover made from cast aluminum. We also installed breathers and baffles.

Get used to it. this is the way your '60s-style Mopar wedge engines will look in the 21st century. As long as they run like this one, you shouldn't have any issues!
