Don't have an answer but apparently there are different windage tray designs to accommodate different strokes on the gen 3 engines. Although what I find interesting is if you look up stroker kits for the 5.7 there is no mention of needing a different windage tray.

However, apparently MMX makes a custom windage tray for strokers. You might try contacting them to see if you may need one for your application?

Thanks for the reply

I eventually found where the built in windage tray in the Durango oil pan is removable … so at least that opens up some options. Planning on the MMX Stroker kit, so will reach out to them for recommendation/requirements.

When I used to build motors (5.0 Fords and big block Pontiacs)… I used modeling clay to set the depth on oil pump pick ups, etc. Also, usually used Canton oil pans with great success.

Why not install Your set up and hand crank the motor and see if there is any rubbing of reciprocating parts?

Regarding the windage tray, the more coverage the better. On the oil pan, which ever one has the best baffling and deeper sump, that should be your go to if it fits the chassis.

About to do the same thing soon. MMX stroker windage trays should work.

Gonna have to do this anyway to check for and remove clearance issues.

Thanks guys. Since the plan is a full rebuild, any thoughts on Stroker 5.7 vs 6.4 vs Stroker 6.4?

If your goal is the best power at high altitude the 426 will do pretty damn well. I guess it would depend on how much you want to spend. 5.7 stroker will probably do ok for a much lower price not having to get a whole new block+parts.

The age old question… how fast do you want to go and how much money $$$ do you have to spend.

I have always been for “there is no replacement for cubic inch displacement” kind of guy but my little 306 Ford outruns the hell out of 347 and higher motors all day long so combination of parts (heads, cam, compression, gearing etc) are key!

Just trying to build fun into the wife’s daily … she decided she wanted to keep Rango vs getting a car payment.

So, time to put some money into Rango and make it something she’ll want to keep driving … a 411 or 422 pump gas daily sounds about right - understressed and lots of torque to get the heavy beast moving.

Then again, 392 is only 7 1/2 % or so smaller than 422 …

Yeah maybe a low mileage 392 with some mild modifications might work? Seems more cost effective?

Either way, if its the Wife’s ride then reliability and smooth linear power should be your focus.

Step one of this process was putting in a lower mileage 5.7 in with MDS delete and 6.4 cam and hemifever tune (mostly wanted the tune to improve the laziness of the throttle response and transmission shifting - without going to extremes).
Step two will be either a complete rebuild on the original 5.7 or a 392. Costs for rebuilding the heads will be a wash not matter which route I take. Since the cost of rotating assemblies are close - cost per added cubic inches goes down even when factoring the cost of a good 392 core. I’m definitely leaning towards a large motor, good heads, mild cam setup for excellent street manners and good power in a fairly low stressed package.
Step three I guess will be a little body work to clean up a few years of parking lot scars (and the sides of the garage 🤦‍♂️) ….

Best thing is this can be a “pay as you go” process without eating the entire bill at once!

While I’m working about 8,000 miles away from the Rango, I bought a few e-books.

The two following clips come from Larry Shepard’s New Hemi Engines: How to Build Max Performance.

Windage tray mods for 4.0 stroke (appears to be 6.4 windage tray according to the images I pulled up on RockAuto - the 5.7 pan is dimpled instead of slotted in the areas of the arrows).

And same for 4.05 stroke:

So a stock 6.4 windage tray with a little extra work would work? Be saving about $50 or so over the MMX one.
