What sort of cubes are we talking about??? Stealth heads and "stroker" really shouldn't be used in the same sentence unless you're building a small stroker and a fully ported set of Stealths.
The MSD looks like a nice unit and supposedly supports 620 HP (max) with the optional pump. If you're planning EFI, chose your cam accordingly.
We are talking about a stroker anywhere from 470 low deck to 512 raised block. It seems like there is a real bias against 440source stuff sometimes. Many folks on cuda hallenger claim to use none ported stealth heads on strokers with no issues. People in this site seem to just not like that company it just seems. We are talking about a street friendly pumped gas engine that eats LS1's like its nobodies business. Anybody have a combo like that?

What has been your experience with 440 vs LS ? I am going stroker but I am curious if you have beating the LS motor fanatics in your area?

Plenty of guys on here have combos just like that. It will run hard and put out a lot of torq. Most of the people on here complaining about the 440source stuff have never owned the product they are badmouthing.
Your probably right, everything I have gotten from them is solid. They are a decent company and if the fact that its not made in America bothers you then I guess they would have a problem with just about any stroker kit. Most of the components all the companies use are manufactured overseas.

I "have" their 528 stroker kit
I "have" their fluid dampener
I "have" their serpentine pulley set
I "have" their one-wire alternator
I have "owned" 'source heads
I have "owned" their distributor
I have "owned" their fabbed valve covers
I have "owned" their fabbed timing cover
I have "owned" their water pump
plus a few other odds and ends.
So I think I have an idea of the quality of their stuff. That said, I wouldn't (and don't) use those heads on a stroker. Spend a few extra bucks and go with Indy's or Eddy's. If you opt for Indy's, buy them from a reseller who will put the right stuff in them in the first place.

My 505" stroker is a 0.030" over 440 with the 440 source 4.25" crank, 7.1" rods, and 17cc dished pistons. I have the older 84cc stealth heads with some mild porting, and they flow decent. I'm using a hydraulic roller cam and cheap CAT stainless steel 1.7:1 rockers, so the springs, retainers and locks were changed to ISKY 8005A springs with comp 10-degree retainers and locks. The cam is the Comp XR286HR-10 with 236/242 duration @ 0.050", and 0.617"/0.614" lift with the 1.7:1 rocker arms.
I just got it installed, so far I have only put about 30 miles on the new engine. I can tell you it revs really fast (I need to install a rev-limiter), and it has more power than my old clutch can hold. I am still tuning it, but it has a nice idle at 850-900 RPM, and pulls about 7" of vacuum at idle (at my altitude of almost 6,000 ft that is not too bad.)
Currently the intake/carb are just an Edelbrock PM intake and Holley 770 ultra street avenger carb.
I want to use the Edelbrock Pro-flow XT system, but don't have the $$$$ for it right now.

Is something wrong with a 4.15 stroker set up? Many people go with 4.25 instead. How does that stroker drive by the way?
The 4.15 strokers use the factory rod journal size. The 4.25 uses the smaller big block chevy size which requires less block grinding to clear the rods. So you get a bigger engine with easier fitment ,for the same price.

depending on what has been done to the LS and what car I'd think a stock stroke 440 w/ decent heads (e-heads, ported stealths...) 540ish solid cam w/ roller rockers, RPM intake, 850HP, 1 7/8" headers, 3800-4k stall and 3.91s or better should do just fine. That combo will run 11's in a b-body w/o NOS. With the extra cubes you'll have a few more hp and more torque. What are you trying to keep up with?

The car runs good, but it is running rich even after jetting the carb down a bit. I need to fix the clutch so I can put it on a chassis dyno and see if the airbleeds need to be enlarged.
The 4.15 stroker is good too. I built a 500" stroked 400 block with the 4.15" stroker kit. The kit (440 source) also used the 2.20" rods (GM bearing size.) both stroker kits fit with just grinding a bit off the oil pickup boss. No clearancing needed around the cylinders or pan rail. On the stroked 440 with stealth heads, in my '69 Coronet, the #2 spark plug is very close to the shock tower where I can't get a normal spark plug socket on the plug, so I bought the short spark plug tool from Snap-on to tighten that plug. The rest of the plugs were easy to get to. I'm using the 1-7/8" TTI headers.
Today I am working on installing a six-pack hood scoop on to a stock flat hood because the RPM intak and Holley carb are too tall. I think the Pro-Flow XT EFI is several inches shorter in height and the filter is in front, not on top.
That's one reason i was looking at that setup, then I can use my stock hood.
