building a 383.. is 440 source the place to go?

ive seen the banners here on moparts for 440 source so i checked them out and im just stunned by how low the prices are compared to small block stuff, mostly the stealth heads for $900

im planning on ordering a set of stealth heads

passenger side water pump housing and pump

serpentine pulley set

and a few other parts. im just wondering how the quality of there stuff is overall or if theres anything i should stay away from

They are the place to go. Just check every thing over real good and there balance jobs suck. I've had 100% good luck, have done over 12 stroker engines useing there parts. A lot of people knock there stuff, that is to bad. There cranks and rods are Chinese made, well so is every one elses cranks and rods. Why pay more?

im sticking with the stock rotating assembly just going to do the aluminum heads and a big cam with an eddy rpm

i need some more torque to move this big truck and the 360 is only getting me a 13.8 id like to move that down to a 12.8

Is there some reason your going 383 vs 440? Or at least 400?? The 383 while they can run good have some real disadvantages... Like the fact it's hard to get a decent C/R piston...

The stealth heads I got were really nice castings.
The springs and retainers are good for a decent sized hydraulic cam, but may need to be changed if using a large cam. The only item to note with the heads, is to use a large bore head gasket.
Their timming chain sets are nice too.

My machine shop re-ballanced one of their stroker kits, but I did not get the details why they did it?
I will pay closer attention to ballancing issues on the other kit I have.

I did get a timing chain oil slinger, and the crank hole was too small to fit over the crank snout. Their windage trays are designed to clear a 4.5" stroker crank, so they are too large (deep) to fit inside a stock style oil pan.
The aluminum rear oil seal retainer was slightly shorter than my oil pan rails, not a problem and maybe the same height as the stock seal retainer? I did not check the height of the stock one for comparison?
The ARP oil pump bolt kit for the HV oil pump are too long and bottom out before clamping the oil pump to the block. I few minutes with the grinder fixed that problem.
440 source customer service was good, and I would buy from them again. Those new cast valve covers look nice

I believe they fixed the chamber problem.Mine were one of the first sets.I used FelPro marine head gaskets and they fit perfect.Been on 2 years and no problems.I did have mine upgraded to Comp springs retainers and keepers for the big solid cam I run.That and they back cut the valves cleaned them up a bit and lapped the valves.That would have been done on any head except maybe a full ported set.Have them checked before you install them.Its cheap insurance.Rocky

check the water passages in the alum wp housing

just read a post on that,the passages are smaller and was causing an heat problem

only what I read though,but worth checking

The problem is the small bore and short stroke when it comes to getting compression , there are ways to get around it , but it's not cheap , NOTHING off the shelf .
