I have a chevrolet 350 bored over to a 355 its a four bolt main the internals are lightened and ballanced and every thing is forged, ok how much horspower can it take before it come apart?

Cam will be a custom Chet Herbert Solid Camshaft, and a demon 850. Its hard trying to find a certian year block what about mid to late 70's?

You can check the casting numbers here to find out what year. http://www.mortec.com/

Her are the specs on my cam: lift 525/538 dur 250/256 @.50 LSA112 Its a nitrous cam RPM range is 4,000-7,000 its not to ratical!

Also how much power can a stock rod with ARP bolts and crank with ARP main bolts take before they come apart I am only taking it to 6000rpm my rods and crank are forged I just want to know for future reference?

This is just a rule of thumb, but I would not go over 425 hp on stock connecting rods with ARP bolts, and not over 500 hp with aftermarket I-beam rods like SCAT or Eagle. If you are going to build a killer hiperformance engine that is pushing over 500 hp, you will want to use H-beam connecting rods.
