93 1500 w/ 5.3L & 5 speed swap

[91blkstpsd]

Im gonna start a build page here for my 93 Silverado. I've done a lot of work on it so far just to get it lookin decent but now its time for some drivetrain work. It came with a 305 and 5 speed but now has about 295K miles on them. I had plans on just fixing up and daily driving but I found a 5.3 cheap... so why not?!

Some brief background....truck was wrecked in passenger side when I bought it. Got for $600





Fixed all the damage myself, swapped out some things and repainted it




5.3L is from a 2004 silverado with DBW
Came with accessories on it but wiring was cut


Parts already collected:
Transdapt motor mounts
Russell fuel rail fittings and connectors
GM EP-381 fuel pump kit
WIX fuel filter/regulator
4.8L flywheel
Pilot and throwout bearings

I plan on gathering few more parts for the swap soon and stick this thing in! Schoenfeld headers will be used and Powers AC relocation brackets.

This is my first LS swap into anything so I'm sure I'll have questions and any tips would be greatly appreciated!

The only downfall so far is this has a cracked head.. The donor truck was wrecked and pulled the manifold bolts out. Hairline crack from one bolt hole to an exhaust port.. Already have another head but its casting #706 and mine are #862. I believe they are the same though..

Where's a good cheap place to buy top end gaskets at?

I got the Felpro MLS and head bolts from Rockauto.com for around $60, not sure if thats the cheapest, but it was the easiest for me. I would look at the Novak adapters AC kit if I were you though.

Thanks man!

Got a little work done this weekend. Sorted thru most of the old engine harness and pulled aside the things I know I wont need and the things I will. Got the motor mounts put on the engine and waiting for the new poly mounts to show up so I can test fit it in. Also cleaned up the trans cause it had a thick layer of grease inside the bell housing where there had been an oil leak at one time. Got the new fuel pump put in as well.

Then I mounted the TAC module on the firewall. FYI- It mounts perfectly where the cruise control box goes, looks factory.

Also mounted up the drive by wire pedal assembly. It wouldnt fit good as it was so I modified it and made a bracket that makes the pedal bolt in like the factory OBS one. Seems to work out good IMO

BEFORE: (the pedal was offset too far over)

AFTER: reshaped and angled different, its straighter now.

I mounted it where when all the way depressed, its about 1/8" off the floor.

New here, I was wondering if I could get a parts list, I'm looking at doing this swap for my 98 Silverado 4x4 with the 3500 and am not sure of things like what I need to do wiring wise and like what you used for a fuel system, my 5.3 motor is out of I think an 01, any help would be greatly appreciated thanks
