I'm just beginning my first stroker build. I've built more or less stock 440's and have dyno'd around 450 hp basically a little more than stock setup.

I've searched around on the forums and 440source is bar none the biggest bang for the buck! During the last couple of weeks, I've traded a few emails with them asking about a complete parts list for the build along with dyno results if possible.

Here's what I plan to run it in.

Early B body stock Plymouth.
3:91
2500 stall

max wedge exhaust manifolds coupled to a full 3" exhaust

Edelbrock RPM performer intake
Edelbrock 800 carb.

Here's where I'm looking for guidance on the engine build.
-440 block .030
-4.350"
(.030 over) -24 (Dish) 1.867" -.018" P/N: 440.500.5080

Does anyone have knowledge on the stealth heads, or are the edelbrock's recommended?

Camshaft?????
Comp Cam Xtreme Energy Hi-Lift .564"

Any help or experience with 440source products is greatly appreciated! I rarely see anything negative about 440source!

Regards,

I forgot to mention, I'm looking at no more than a CR of 9.5:1.

Thanks

Yes, you're right, it would probably be a good idea to shave another .5 pt out of it. I'm jusr paranoid to ping and overheat problems.

I would still build for quench just use the large dish to lower the C/R... Quench is always beneficial...

Why build a big motor and choke it W/ manifolds?

Eventually I plan on installing a crossram setup. Didn't the max wedge/superstock manifolds flow well?

Look in the tech archives for plenty of 500 inch stroker builds.

I also wrote an entire book on the subject which you can find at various Mopar parts dealers.

I don't think you'll need the 3.91 gears if you build a 500 inch engine. 3.55 will work just fine as will 3.23 gears.

My 496" 440 source motor runs 10.4:1, .034" quench with the Eddie RPM heads and is faster on pump gas than on race fuel. The cam is .604"/.597", 264°/259° solid. I've spun it to 7000, and the timing is 18° initial and 34° total. After tuning it is putting out right at the 600HP mark and 600 ft.lbs from 3000 on.

Excuse my ignorance, but what does it mean when you guys use the terminology "quench"?

I am leaning toward eddie's heads, but the price of 440source's stealth heads are very attractive. Has anybody had/know of someone with experience using those heads.

Quench means at least part of the piston comes very close to the head at TDC. The near contact stirs up the mixture to help cool it and prevent detonation. .040" clearnace is considered ideal and fairly easy to get with Ed or 440 Source heads. Set the flat part of the piston at zero deck (piston comes right up to the top of the block) and use a common .040" thick head gasket and you have it.

Careful piston choice, deck machining and/or custom pistons may be required to get 0 deck but the benefit is significant.

I think you are ok, (cannot remember how they route) but you may want to check to make sure the angle plug of the Edelbrocks will work with your manifolds. Otherwise the straight plug Stealth will have to do.

The 500" stroker will be choking if you use the stock Stealth heads. You'd need to go with their CNC'd heads or step up to something else with the same or better flow.

A zero decked block with a closed chamber head and .040 gasket will provide the quench. What you need to figure out is which of their pistons will give you your desired CR with the above.

I have a 440Source kit (528") and I'm pleased with what I see HOWEVER, it is not a "drop in" assembly. So far I've noticed that the pins don't fit in the rods and the rods will need to be honed. It looks like the damper (theirs) isn't going to fit the crank either.

so 915 with .040 quench what compression can I run and still use pump regular or premium?

Yep, run the items you listed, get the pistons for 0 deck (10.5:1 compr ratio), get the Stealth heads (they will be fine on the street), paint 'em same as the block and tell everyone it's a 440 with just an aftermarket intake...

Yes because the aluminum pulls heat out of the chamber area much quicker than iron.. And depending on the fuel you have available somr guys run over 11-1 on pump fuel... I'm building mine at a true 10.25 cause I'd rather be conservative & know it will be safe with Californias lousy fuel & still make all the power I need for a street toy..
