I`d like some suggestions on where to get a 331 Short block ,or maybe just a kit. There are SO many places on the `net to get one I don`t know who has good service and who to stay away from. This will be a Mild 331 in a street car (no steel crank). Thanks ------------------

MAV, Of course you already know the answer to that: Get it from our very own ALEX @ MMR!!! He'll get you a Great Deal (which is defined as: Best Cost versus Quality) and then you'll have 1-on-1 customer service and most important - be confident that the package will perform to the level you desire!

Sounds like good advice, but in case Alex doesn't sell stroker kits, you might try http://www.adperformance.com Good Luck! ------------------

I bought my SCAT 331 kit from www.cnc-motorsports.comI think the vendor is less important than the manufacturer, but thats easy to say when everything came to me quickly, correctly and undamaged.

I got my "Scat" 331 rotating assembly from CNC as well, good service , good prices , knowledgable staff.
I went with their cast steel crank, forged JE pistons , Speed Pro rings.
Most of the other parts I got from Summit, they are a highly reccomended parts source.

Sounds like we built the same engine! I got the exact same parts combination. Summit is of course convenient for me being a few miles down the road. MAV,
depending on who's kit you buy you may not get rings or bearings included. Some kits have changed over time. the SCAT kit I bought did not include rings at the time of purchase (that was back in 2004) but i think they do now. I had to buy bearings (clevite) seperatley.

Among the affordable stuff (Chinese Imported) the Scat seems to have a stronger following than the Eagle. Callies has their own less expensive line that is a step above the current Chinese offerings, but I don't know if they do Ford stuff yet.Callies
Scat
Eagle In that order. Of course, if you want to spend well over $1k on the crank, Crower, etc can set you up. Good Luck! ------------------

I would like to buy American ,but how do you know before hand!
I.E - i was very disappointed when i purchased the top of the line Milodon hi-output small block water pump, the "Made in Japan" embossed across the front of the pump took me back.
Now, it worked fine, for about 18 months, a Stewart pump replaced it & did lower the temp. approx 10 degrees with no other changes & its made in the States!
These compmaies should have to tell the public if this stuff is produced offshore, don;t you think?
Now i got that off my cheat, how does one know which stroker kits are Am. made?

from what I have been told
SCAT: Cast/forged in China - machined in US
Eagle: Cast/forged and machined in ChinaI think thats why some hold the SCAT stuff in higher esteem than the eagle stuff. The machining is the important part but you can still screw up forgings and castings too, leaving porosity, inclusions, forging laps etc.. in the parts. Thats true for the crank/rods, but the JE(SRP) pistons in the SCAT kit are entirely US made I think. if you want to know all those details you could contact SCAT and Eagle and ask them. http://www.scatcrankshafts.com/index.htm

http://www.jepistons.com/cat/srp/ My SCAT kit was PERFECT. I measured everything during installation and all was nominal. Endplay was perfect. That was my experience Im sure others have comments but I will buy SCAT/JE parts again. I think its possible to get these kits with lots of other pistons, probe being another offering. You would need to research those too. I think you can even get them with KB hypereutectic pistons to save a few bucks, but I didnt really see the point. Youll have a whole other effort trying to figure out which rings to buy, and which bearings to use. Speedpro was the recommendation I got - I gapped mine myself, but some folks like the gapless rings We have not helped you much regarding short blocks, if i was to do this all over again I would probably buy a short block or a long block. Once you buy a stroker kit you will need to get it balanced. By the time you go to all the effort and expense I think it might be worthwhile to just get a shortblock. Shortblocks are even more of a risk though because you are paying someone to assemble the parts, so you really need to know who youre trusting with your money. Some of my engine buildup is on my website (link in my sig) for more information. ------------------

I bought my 331 kit from DSS Racing. Great kit, high quality stuff. Crank, Rods, pistons, rings, bearings. With a Comp 274HR cam and Edelbrock heads, I made 404 HP at 6000rpm on the dyno. The guy that built the motor was very impressed with the quality. Easily balanced. They were great to deal with on the phone, too. 2 years on it, and still going strong.

I am in the process of getting the last parts to build my stroker,and have been looking at varies crankshafts, Scat, Eagle & Summit in the forged section. What is interesting is that the Scat & Summit cranks need narrow bearings where as the Eagle does not. But the Scat is cross drilled and the other 2 are not. Compare Chart Any thoughts? ------------------

Steve-UK,The cross-drilled crank journal issue was an accepted 'good' hot rodding trick back in the 60s/70s, but with the development & common use of 3/4 or fully-grooved main bearings, I wouldn't give any crank "extra credit" for that reason. Ryan
