What do you mean by "best". Do you mean cheapest?, strongest?, best value?

440Source is usually the cheapest. SCAT has rotating assemblies with a Mahle piston which I think is better than the ICON piston that 440Source uses. You can also get a K1, JE combo which works really well. Lots of choices.

Instead of asking for best you should tell us what you're trying to do. What heads do you have? What compression ratio do you want to run? What bore size? How deep do the valve pockets need to be?

There is no "kit" but AndyF has a good piston selection chart in the tech section that helps you with your selection.

Check out the discount section on 440source. Looks like a good deal on a crank and set of rods.

If you want the best, and plan on using a stock block, invest in a center wieghted crank to make the block live a long life. I highly sugest you go with a 400 block also at the power level you want. When you say best, then talk to some of the great engine builders on this board and have them set you up with individual choices for pistons, etc. Your best results will come from going that route. Ask me how i know😀😀 your dyno results will love you for it!

I have Molnar also with JE pistons....excellent quality on the crank and rods.

What cc are the heads? You'll need to know that to pick the correct piston. There might not be an off the shelf stroker kit that gives you what you want. If it was me I'd use a Molnar crank with 7.100 rods and then look for a piston that gave me the compression ratio I wanted.

Are your Stage VI heads any good? I think they would be the weak link in your engine.

Spoiler Alert: Sarcasm ahead!!!!!

He did say BEST.....

If you want the BEST then you start with a Winberg or Sonny Leonard billet crank, Carrillo or Crower rods (there are others but key is they have to cost over $1000 per set), Gibtec billet pistons, pins with DLC coating. You'll have $5000+ in the rotating assembly, but it will be the best at least the best made in USA stuff.

Then it goes in an aftermarket block, because it'd be a shame for a stock block to wipe out that amount of money in parts.

Then you put your Stage VI heads on Ebay and buy heads that really work.

Or maybe you didn't understand the meaning of the word, "best".

Two “problems” I see with the proposed build of “750-800hp”.

The stock block and stage 6 heads.

The stock block will break(at some point), and the stage 6 heads likely aren’t big enough to make 750-800hp(unless they are the big Chapman’s).....without help from spray or boost.

If the goal is a “real” 750-800hp NA for a reliable bracket type build, I think the plan could use a few revisions.

Who is Sonny Leonard? I know Sonny BRYANT makes crankshafts but not so sure about Sonny Leonard grin

I agree with the above post about the stock block, it would be a shame to put all that money into an engine and the block fail and trust me it will.

I believe a 400 block with a good aluminum main cap and good aluminum rods will live for a while at 800hp but only for a while.

I wouldn't spend a bunch on crank and rods for a stock block build b/c when the block breaks, it'll likely take the rotating assembly with it.

Like Fast68 and dogdays said, you need better cylinder heads.

Just dial the expectations down a bit and the combo will be fine. A 440Source kit with Stage VI heads should make 600 hp all day long and last a long time in a stock block.

700 hp would require some professional engine builder help with the cylinder heads and cam profile.

800 hp is very unlikely.....

If the stage 6’s will in fact be used, along with a stock block, I’d build either a 505RB or 511B, flat top pistons, easy on parts roller cam, and it would make whatever it makes.... which should still be enough to cause some issues for the stock block.

With std port stage 6’s, I don’t feel that 700hp would be a “slam dunk” by any means, on the dyno here.

You could always swap out the top end down the road for something more suited towards bigger power numbers......if you feel that you’d like to expidite the demise of the block.

Stage VI heads on a 440 block require special intake manifold or funky spacers.

Personally I'd sell the Stage VI heads and buy Trick Flows but I understand if a person is going to use what they have. I usually build with what I have on hand too.

I have a strong suspicion the OP has the stage 6 RB intake already.

Not sure why everyone sez there's a for sure limit on power being the 'block breaker" cos there's more than a few 400 based turbo motors I've seen over the years in the 8's and living even w/stock caps. Detonation can end an aftermarket blocks life just as easily cos we've all seen that a few times and my lowly 9 second 470 is still ticking and kickin.......... thumbs
