How much HP can a stock rotating assembly handle. Chevy 350. I take it someone doesnt know what a rotating assembly consist of. Your making this question more complicated than it is. Everything on the rotating assembly is stock. crank, rods, pistons, ect.... How much power can I put on these stock parts. I know its more than 1 HP per c.i.

who would have a clue you were talking about a 350? we all have different engines.Are you asking what will break? when will it break? does your 350 have a cast crank or a forged crank. Is your engine new or was it from a 1967 car? Do you have 2 bolt mains or 4 bolt mains. Is the engine original condition? does your engine have cast pistons? Give us some clues,,,

I don't know about that. If it is out of a 96 model truck they didn't have but around 255 hp and 330 lbs. of torque.

A few years ago, a friend of mine used an autozone short block for drag racing. Lasting him about 2 years of racing every weekend and drove it to work. I would say a 600 to 650 Hp build.

200cc dart heads, compcam 292H, Victor jr, 750 DP, 300hp shot N02, 3500 stall, and 4.56 gears.

Finally developed a rod knock after eating 20lbs of n02 every week for 100 weeks.

More torque, lengthen the stroke. More power , increase the revs. So with a stock engine all you could hope for is a longer accelerator pedal to squeeze more hp out. As the piston crown reaches tdc and heads back down at 2000rpm it wants to leave the wrist pin behind. At 6000rpm the wrist pin is still trying to hang onto a cast piston, but the force has increased dramatically between going up, stopping and going back down...........the rest would be history.
It would be a good bet to see what would let go first, valve spring, valve, piston crown, rod, crank, bearing????????

Might I suggest this post isn't the way to get answers.You do know that Chevy did build a number of rotating assemblies.:rolleyes:
The adventures that other guys have taken with marginal parts isn't the good advise the guys on here are going to give you.
But you need to be detailed in what exactly you have before anything can be determined.
Now(God knows why I am posting this)I am the third member posting this request for more info.................the rest is up to you.

I made 806 in a 454 with stock rods and stock CAST crank but with forged pistons - but good cast TRW stock replacement pistons would have held up, as well. It, also, had been turned as high as 8200 in the lights. I used the cast crank because it was 5 lbs less reciprocating weight. Of course, I did magnaflux those parts to find good stock ones.

as seen as the question is somewhat open ended.. with way to many being anal about it..
most chevy 350's don't have forged factory piston, nor do they have forged cranks..
so to answer the question in the way I take the o/p asking it..
if you go grab a 350 out of a junkyard and bolt it in, without rebuilding it.. changine the cam.. and adding headers/etc..
most will make 350hp without blinking,, cast crank and pistons,2 bolt mains.. thats going off the millions of engines out there and the most likely one you'll come across..
even if the one you find has forged everything and 4 bolt mains, it don't mean anything.. it might give up way before a cast piston/crank one will. like anything it's the luck of the draw..
I beat the living crap out of a 100k 350 with cast crank/pistons/2bolt mains.. and had no problems,,
I've had low miles truck engines(forged crank/4 bolt mains) spin a bearing..
but figure you're pretty safe with any 350 handle'n 350hp no matter whats in it.. as long as it's healthy..
cast parts don't like shocks, so if you dump a clutch at 5500rpm you might find the crank on the ground..
cast pistons and happy gas isn't a good idea either.. as you have to be dead on.. with the tune..

having said that.. I sprayed the crap out of a pontiac 326 cast crank/rods/pistons.. for a good 2 years..
but thats was more of being lucker than good.. ;)

No sure about many being anal.Guys will tell us about their adventures with cast whatever and is that the kind of advise we want to provide?? After all that is saying one guys accepted risk is his O/P's risk as well.

But getting back to too many being anal,a number of members have tried a number of times to advise this O/P the best way they could by asking for details on what he has and in that way give him well founded answers. The O/P wasn't for coming in those details. Now I have been on forums like this for many,many,yrs. It is my experience that when O/P's don't post back with more info,the main question they are asking they know what the answer would be and just don't want to hear it.Or can't be taught anything.

We constantly forget the foundation of Hot Rodding isn't a budget or the cheapest found,but building the best.15 yrs ago when imported parts invaded Hot Rodding it took out one of the cornerstones of Hot Rodding and with much of it junk.

So here here is my blind unfounded answer not knowing what exactly what he has.Yes,Chevy produced a 350 hp 350.:rolleyes:

what, the foundation of hot rodding ,, are u daff..
it was bolting together parts found at junkyards/swaps and a few speed parts..

like I said any chevy 350 will handle 350hp without blinking..
getting it to honestly make that is another story..
