How high can a bone stock LS block rev?

How much can it handle assuming the head is built?

Even if your head is built, I wouldn't take it much higher than that.

 

Hmmm...


Any other suggestions?

 

safely..assuming everyday i wouldnt go more than 7k. shotpeen the rods, arp rod bolts, block girdle and balance your bottm end then you'd have no prob going up to 8-9k. if you want to rev to 8-9k easy get a VTEC block

 

I rev mine to 85 with crower valvetrain and eagle rods,JE pistons

 

I take my stock B20z bottom end to 8000 RPM and it sees 7500 a lot.

I wonder if that's healthy

 

been doing if for years on this block. Not me personally but the previous owner.

 

stock block stay with stock reline like 6,800

arp rod bolts shoot peened ls rods, ls rods renotched for gsr rod bearings, blance whole roating assemble, and your good for 8k+

Well we had an ls with bullfrog computer (stock block, bottom end, head, cams), we turned this car on the street and dragstrip 8100 rpm everyday more than once a day since mid 1997 till early this year when it finally blew up. Stock rods finally let go, cylinder number 4 rod failure, snapped the rod in half, then smashed the rod cap into two pieces and sandwiched the two pieces against the bottom of the sleeve and the rod journal, and well that was the end of that rotating assembly. Block was usable after boring. Suprised that after all that beating we gave it it actually lasted that long, had pictures of the rod and cap on here a while ago.

here is when it happened. hahahaha

Dang, that sounds pretty good. Any other comments?

 

Stock ls motor can be rev to 7500. Stock shortblock can be taken to 8000.

I could rev an LS bottom end to 10,000 RPM... But how long will it stay together? If you want to rev an LS block past 7200 or so I would at least balance the entire rotating ***'y and use ARP rod bolts. I don't believe that shot peening the rods is necessary for 8000 (or so) RPM.
