Brainstormin' 440 vs 5.9 ...

[318willrun]

I get it. I like it. I think it's cool you wanna do the 440 "as is" for like a base line. What bolt ons do you plan (if any) like headers and such?

It will get the truck's set up now. Headers, the converter that's behind the 5.9, and there is 4.30's in it but that may be too steep for the 440. That's it. The 440 has a street dominator on it now. I do have the factory cast as well

I have to strongly disagree with that.

You don’t have to just disagree, you actually have proof.

You can disagree but I’ve pulled stock piston pieces from the pans of at least three 440s over the last forty years that I can remember. These were cores but I’ve also seen plenty of broken skirts.

Likely from tuning mistakes. Cast pistons can take a beating, they just can’t take detonation.

well, let me try and clear this up. I have zero intention of "building them similar" and "let them battle it out". LOL. My goal is to lower the trucks ET. I will build the 440 with zero regards to the 5.9. All intent will be a 440 that will lower the ET substantially. But I plan on running it as it is just for my own curiosity, and others appear to have interest as well.

That sounds awesome. You do realize that the same things that made your 360 run well are going to be what will make your 440 run well. Intenional or not. Will it be a pump gas build?

Does the 440 have heads on it now?

• well, pretty much any 4-cycle engine looks to the same principles for performance, so be it a 289, 283, or 440 the thought process will somewhat reflect. I'm at least 2 months into this game ... lol And yes, pump gas with cost somewhat in mind, as always

OK so cool It won't be slap handicapped then. Street dominator's a good choice. Leave it there.

It is sitting fully assembled, from the Torker 440 down to the oil pan. Ready to drop in the truck after I put the RV oil pan back on.

Just looked at my own video, it's a Torker 440 (Not SD, couldn't remember.... LLOL)

Still better than factory.

nobody has brought up the friction of having a larger diameter piston and more stroke. maybe some snake oil moly lube in the cylinders and/or oil would gain a tenth?

Let me disagree with the old folks. It’s more fun that way.

So, if you are using pump gas then the cast iron head 440 compression ratio ceiling will be similar to what the 360 has.

Love the accelerator pump style choke. lol. So what heads are on it now?

If you are gettin all that for $500, I wanna shop at your parts store!

Do you know the weight difference between the low comp pistons and the six pak pistons? I have been looking, but can't find the weights.

 

[fishmens67]

weight difference between the low comp pistons and the six pak pistons

low comp 820 grams
six pack 872 grams

fresh 452's. Cut .030 to make up the difference in the thick gaskets I used, so should be factory compression. I also used new 440 magnum valve springs (retainer inside the spring)

How thick was the gasket you used?

I don't know..... .050?? I can't even remember the part number, but I usually use Fel Pro. I had the calculations then of the original gasket and what I'm using now, that's how I came to the .030 mill.

Thanks.

That made me laugh. Thanks.
With the bottle turned off I activate the nitrous plate and use the fuel enrichment as a choke. Works great.

I have yet to see any 360 carry torque through the rpm range like a decent 440, not even close.

But imo, the 4.30 gears will cancel the 440s torque advantage. If 318wr was running 3.23s.........?
And (no offense) when did a 7.4 to 1 440 become decent?

Why? lol.
Get a steel shim in there, while you're in there measure, probably figure out to be 8.5: 1
