Picked up a 5.3 for 400 Friday complete with the harness and ecm gas petal and the tac modgule,the damn gas petal harness was all wrapped up in the donor trucks harness under the dash it took for ever to get it out

 

 

Not sure if I should do cam bearings or not while it's torn apart i was told it had 200k

 

Well got the engine all torn down and currently at the machine shop for a vat and cam bearings,tonight since I have time and nothing to do I converted my harness that I got with the 5.3 from dbw to dbc.I followed the instructions off lt1swap.com he had alll the schematics that was needed.Instead of running wires to the pcm I used the pins from the tac modgule plug that were already ran to the throttle body so all I gotta do is run 1 extra wire because 7 are needed.Wirings not my strong so I hope I did it right seemed pretty strait forward but I won't know till the motor in and ready to fire up.

 

O yea we got a clean block with new cam bearings!Now for the fun part...to order parts and assemble!!

 

You better pull that barbell out the back of the block. No telling what was traped in there...

Once that's out, You can use extensions to drive the plug out the front of the block.

This should be done to remove debris and properly clean the passages.

Also for the price, I would recommend replacing it.

 

Thanks for the heads up 1fastbrick!!I would of looked over that,I'll order one,i think you've put together a couple motors would u have any recommendations for a brand for the main and rod bearings??

 

Man good work coming along!

 

I have used the ACL in the stock rebuilds. I haven't had an issue so far.

 

thanks S14serge got more progress done this weekend
