Hey guys, here is another recent build for you guys to enjoy, this one is shipping to Germany for a Autobahn lover, after discussing their needs we decided a MMR 1500 Series was perfect!! In a effort to shed some weight the Factory iron block was replaced with a MMR 2011 Alloy GTDS (dry sleeve) which can go as large as 3.650" bore size safely for applications under 2000HP.
This particular build uses the M2500R piston and pin upgrade, these are the same pistons and pins used by team MMR in our 2500HP pro mod and outlaw GT500, enjoy...
We start with the 2011 block, it has been dry sleeved, machined, double torque plate honed and bored, decked and hot tanked, ready for assembly (we will do a seperate write up of this process soon).
Below the MMR steel sleeve can be seen, the sleeve material used is the same that most top fuel and funny car teams use. They are a press fit and VERY strong.
After checking bearing clearances we install the Heat treated main bearings, ARP main studs and crankshaft.
Next we focus on piston and rod assembly, these are Billet Manley rods (the strongest steel rod available for the 5.4 - period), they include 7/16 ARP 2000 Rod bolts. They are paired up for matching weights and assembled.
This build uses the 9310 Steel pin upgrade, the quality and fit of these pins is second to none. Team MMR has tested them up to 2500HP!!
Once the rods and pistons are connected we focus on the rings.
This build uses a Total Seal AP Steel ringset, very tough and durable above 1000HP. The rings are filed for the application and installed beginning with the oil ring. Unlike ceramic and teflon coatings the MMR "red fire" coating will not flake or rub off, it is actually part of the metal skin structure and penetrates beyond the surface.
Next we install the heat treated Clevite rod bearings, the burned finish is part of the final heat treat.
Next, its time to send these bad boys home, each one is loaded into a ARP ring compressor and with a simple 2 thumb push, they glide into their new home.
The shortblock is now done and we install head studs for part 2 of this build -
Thanks for reading, if anyone has any in-depth questions let us know, for simplicity much of the technical info and building techniques have been left out.
Come back later for part 2 when we assemble the longblock!
