440 Source 543 inch stroker kit part 1. What do you get?

A look inside the 543 stroker kit. What are you getting and is it worth the money?
This short series will go over the ins and outs of stuffing a 4.5" stroke in a 440. It will not be a comprehensive build video but instead focuses on the differences between a stroker and a stock rebuild.

Excellent video. I'm looking at stroking a 383 to 496 for a willys gasser build

Motor home engines and those internals were just for torque. They were purpose built to spool up and hold an RPM using everything that rotated inside as a source of momentum to deliver that torque, so the weight of the pistons and rods were intentional. I wouldn't characterize that stock stuff as garbage- it was just for a different purpose than what most gearheads would intend to keep for a HP performance improvement in a rebuild. That being said, I have a 440-3 in a little short boxed 78 d100 pickup truck that was installed "as is" from a transplant, and it's only right that it needs to be seen to. To see a commentary about what 440Source is sourcing (albeit from China) for this build, gives me some options to consider. It sounds like 440Source is a very good group to reference. Thank you for putting this out there.

good to see you again great info thanks

The oil ring seems to get into the piston pin bore on that ICON piston not sure how that will affect things or if that is a factor at all. Seems like a cool build.

Had a little ol' 440 in it lol. My 76 new yorker has the same one. Just a little cutie ya kno.

You could use 1135g steel shim head gaskets that are .018” thick compressed. I used them many times with iron blocks and iron or aluminum heads. Never had a problem with decked block. My 11.3:1 Indy headed big block also has these gaskets since 2 years now as did my previous big block with rpm heads.

Nothing like some horsepower to get the blood pumping in a gear/ machinist head! I am guessing the deck height will help running pump gas. Looking forward to next issue of "Ridgewood Machine Magazine" on how to hotrod a lead sled.

I swear these stock motors was prepped for boost or blower all day 5 to 6 pounds of boost .... ultimate tamed daily driver.

[baddaxx]

Your giving up a LOT with that lack of quench... IMHO its worth it to get custom pistons..

[brandonwalsh]

What about if I use bme rods and billet crank?

[claymahaney]

they say the crank and rods are built by scat

[arthurrose]

Hi- you state your 1972 Imperial came with a CAST crank (by the way, Chrysler cast from steel, never iron) but it wasn't until a bulletin issued by Chrysler in October, 1972 stating 4bbl 440's would start receiving either forged or cast. My non-hp 1972 New Yorker Brougham is actually forged with EXTERNAL balanced harmonic balancer which has the elliptical counterweight, but thinner 1 inch instead of 2 harmonic balancer. When I saw the cast looking damper, I thought it was a cast crank. When I dropped the pan, I found a forged crank with thick width rods (6 pack rods). The "T" in the vin means not HP, the motor has that balancer because of the heavy rods, and I know the previous original owner who never touched the motor. Are you sure your 440 motor isn't forged(crank)?

[vinskeeter]

Can you clearance the oil pick up boss and re route the pick up tube to allow for an internal oil pump?

[Stevesbe]

I had a 67 Newport 2dr with a 383 I could burn tires for miles with that boat

[johnfry]

Any plan for the heads ? Should be a cool build .

[dynodon]

What are you going to do about clearing the oil pickup? With that much stroke it would hit.

[moparorange]

What harmonic balancer will you use ? Do you remove weights off flexplate / torque converter since internally balanced ?

[VegasRT]

I hate to say it but if it werent for China we wouldnt have alot of affordable parts to build engines with or build cars in general. But I you have to run a custom external remote oiling system because of interfence with that 4.5 stroke crank?
