while were are at it I havent seen a bent valve, broken spring, compressed lifter or bent pushrod on here

 

Go to the hemi forum for thoses failures

 

Dont dwell just in the truck section. Timing chains do break, stock or double roller. All I did was state my 2 cents.

 

 

From experience, 5.3's are very durable...so far there haven't been any problems with mine and i like to ragg on it quite a bit, as well as some of my friends...if you've seen the videos i've posted you'd know... I've been told that the weakest point of a chevy truck is the tranny, upgrading components on your transmission would be a very good thing...But upgrading your engine parts would be good as well, just depends how much you're willing to go and how deep you pockets go...this gets expensive after a while

 

go to the dodge forum for ALL failures. **** dodge.

at my old dealerhsip 80% of truck engine swaps were dodge (low mileage too), 15% was ford, the other 5% were 305s, 350s and 4.3's, ZERO% were genIII V8s.

i'm not a trash talker but this is the only exception. lol

 

Well Just To Say I Have Turn My 5.3 74oo Alot No Problems With Rod R Main Bearings.
But I Have Seen Rods Break On A 5.3 Looked Good To With Half The Rod Hanging Out Of The Block

 

Would you claim the failure you seen was do to OE rod bolts?

 

The 4.8 and 5.3 engines are pretty strong from the factory....the trannys.... well thats a different story.
