    The 4.2 is 202 horsepower at 5,200 rpm, 252 pound-feet of torque at 3,400 rpm.
    It is an Essex engine though. The torque is due to the longer stroke. Was more
    of a truck engine. For all that your doing, I would think a 4.6 V8 would be the
    better way to go. Would like to see what you get out of it -vs- a tuned 3.9
    V6.

    That's a nice looking engine. I'm looking at photos 9-11 and wondering if you did anything to the crankshaft counterweights? They look like someone went over them with a machine tool of some type.

    I'll be interested in everything you post. I have a 2000 3.8L from a Mustang and all the parts (I do need to replace the turbo pistons that came with it) to take it to 4.3L with a slight overbore. In my case, I'm going to have a nearby machine shop do the engine, but I'll be responsible for bringing them all the parts (everything including bolts, gaskets, plugs, etc.). So, I do have to educate myself somewhat, and be smart enough to order the best & correct stuff.

    If You're LQQKING To Build A 4.3l Stroker You'll Need The Guts Out Of A 4.2L V6. Bore The Same Pistons Different Rods Different, Crank Longer Stroke. That Gives You The 4.3L.

    Ordered Stud Girdle From Tom Morana In Canada(GREAT GUY). To Install On V6 4.2L. You Must Trim Down Main Caps, Not A Problem Their As Big As On 460 V8 Eng. Just Leveling Off The Tops To Clear Stud Girdle. Arp Studs And Nuts, Make Sure To Ask Him (Tom) To Send All Same Length. Front 2 Are Shorter If Just Using Studs Without Girdle And Stock Oil Pan. Had To Use 4 Wheel Drive V6 Oil Pan For Longer Studs To Fit. See Pics To See What I Mean. Engine Oil Pan fits 1997-2009 Ford F-150 E-150, This Will Save You Some Time. Melling V6 4.2L Oil Pickup Tube. Make Sure All Clears. Put A Piece Of Clay Over Pickup Wrapped In Some Plastic Like A Sandwich Bag And Test Fit Oil Pan. Remove And See How Much Clay Distorted, You've Got To Have Some Room To Pickup Oil.

    Man, looking good. As a suggestion, hope you test fit the oil dipstick to make sure it did not hit the crank counter balance disks/weights. Also need to test the oil dipstick to make sure it would slide in and out when the tube is installed and oil pan is in place. Second, hope you turned the crank over with the dip stick tube installed to make sure there is no obstruction. I had an issue with the dipstick being slapped around by the crank counter weights. Almost broke off the bottom of the dipstick. Now, the dipstick is out of the motor 99.99 percent of the time. My builder tapped the top of the inside of the dipstick tube and used the same thread size set screw with a small T welded into the top of the set screw which now acts as the oil dipstick tube plug. The dipstick tube must be plugged to allow for vacuum in the bottom of the crankcase.

    The 4.0 V6 loves boost. 400 HP is possible with the Stage II Paxton system.
    Too bad it will cost you $5300, yuk...

    Still, would like to see this when it's all done. Will be one of the few with the 4.2 V6.

    I am waiting for someone to put the Godzilla 7.3 into an S197; it WILL fit.

    The REAL eye opener would be the Barra 4.0 I6, they also fit, and are what is in
    the S197s in Australia, and produce more HP stock than the 4.0 V6. Someone
    sold some here before... If the Coyote was a V12, the Barra would be one
    bank, that's how big the heads are...

    Heads Are Ported And Gasket Matched Along With Lower And Upper Manifolds, All Ported On Lower And As Far As I Could Reach In Upper. Have Phenolic Spacer I Got From (Tom) For The In Between!! Removed And Welded Lower Intake To Remove Air Injectors For EGR System. Nice And Open!! It Took A Lot Of Time To Get These This Far.

    Changed Out Valve Springs And Keepers (Comp Cams 26918-12 Beehive Valve Spring LS1/LS2/LS6 Pkg of 12) Melling Keepers Used Stock Upper Retainers Couldn't Find Tool Steel From Comp Cams For Proper Fit. Tried 2 Sets 1 Fit Spring But Not Retainer Other Fit Retainer But Not Spring. (That Sucked) Expensive Failure! But Moved On!!

    Just remember, if you are going to polish the ports, do not do the intake
    side. They need to be rough for fuel aromization, and don't remove
    the bridge, or grind it down.

    My wife calls these dirty pictures. Ha, I think they are a show of beauty. Great photos and a lot of long hard work. Think you will be well pleased with the engine performance as a result. Thanks for the picture show. Brings back a bunch of great memories.

    Hi did you machine down a pocket for the bottom of the 918 spring to sit for the right seat pressure I think it's .030 not sure if it's for coil bind also. Anyway good work kind of wish i had welded my lower EGR after looking at yours.

    The color of your block is nice I've been trying to choose a color for mine and looking at yours I'm in. Not a fan of stock black or Ford blue. Is it painted to match your 2000 mustang red?
