March 29

Months later I've finally painted the other side of the block.



March 26

FINALLY landed my new cam from Texas Speed!

March 22

Few more parts came in. I decided to order new rear main seal and front seal. The new covers that I bought have new seals on them BUT will be difficult to align the covers. I will remove the seals, align the covers correctly THEN install the new seals.

March 19

I wasn't paying attention when I purchased the connecting rods. The plan was to reuse the stock pistons and just replace the weak connecting rods. The stock pistons have a press-in wrist pin and what I accidently bought was full-floating connecting rods. As you can see in the photos I can push the wrist pin out by hand and cannot install clips onto the stock pistons to hold the wrist pin in place. Darn (Sarcasm). Guess I will purchase forged pistons too. Luckily, found pistons that use stock ring land sizes so I can still use the new piston rings I've already purchased.

November 06

Removing the tape from the day before. I missed a spot! Taped off the block. Attempted to use a wire wheel to knock off the old paint, not successful. So I used a flattip to scrape off chunks of the old paint. Coated with primer and finally a coat of black.



November 04

This is the rear main area of the block. You wont even see how good this came out when everything is assembled. But I'll know it's perty.



October 23

Picked up the block from the machine shop. He did such a great job getting it cleaned up! New plugs for the block. Honed cylinders. New cam bearings installed. Decked the block about 0.004"



October 07

I purchased an OBS Builders Guide which has some articles showing off installation of products. New products lists, etc. Inside there was an article of Boyd Coddingtons build for Eddie Van Halen. What makes this sad, Eddie Van Halen passed the day before I purchased this magazine. You will be missed Eddie.



September 26

FINALLY, FINALLY, FINALLY found a simple fuse/relay box that I liked for the 5.3 harness. I can make this water tight and will have a cleaner look. Purchased a Rear Main Housing w/seal. I must have blanked because I bought the alignment tool that is used to align the housing to the crank WITHOUT the seal. Oops.

September 16

Getting the block ready for the machine shop. The lifters were stuck. Reason? Quite possibly this engine sat for a while before I purchased it. Few careful taps with a long flattip and they came out. Picture showing the new lift plate in action. I'M IN LOVE



September 12

Purchased a lift plate to make lifting the engine easy peasy. Purchased cam retainer and bolts. The revised design of the retainer REQUIRES new bolts because of countersunk bolt holes. Ridiculous how expensive these bolts were!!

New OEM piston rings because I'm still going to use the factory pistons. Put up some new signs in the garage. Fancy.

September 05

Finally finished polishing the combustion chambers on the other head. Lapped the valves and assembled the head. Perty.



September 04

More goodies came in! LS2 Timing Chain, ARP Timing Cover Bolts, Camshaft bearings, rod bearings, main bearings and of course Plastigage.

August 29

Lapped valves on one of the heads and now assembling. Highly recommend using a tool like this Matco LS Valve Spring Compressor.

Valve Spring Compressor for GM LS (MST1656) - $30.95 - Matco



August 26

The MUST HAVE tool for any engine builder. Throw away those old ratcheting piston ring compressors and feast your eyes on this beauty. Brian Tooley Racing Solid Ring Compressor (Many companies make these, need to know your cylinder size). The tool is tapered on the inside. Just place into the cylinder, this allows the piston rings to be compressed evenly into the cylinder with a very, very, very slim chance of breaking rings. Genius.

BTR Solid Ring Compressor (BTC-BTRRC3780) - $39 - Summit Racing



August 25

All trunnions have been upgraded and ready to be reinstalled.



August 24

Installing the Brian Tooley Racing Trunnion Kit. Left hand is the upgraded trunnion vs OEM. OEM trunnions have limited travel while the upgraded one can physically rotate 360 degrees. Solves the possibility of valvetrain bind with larger lope cams.



August 23

Short and sweet pictures comparing the factory valve spring to the new COMP Cams valve springs. They are much larger and taller than OEM. With this spring you cannot use the factory type valve seals. Dummy me already purchased OEM style valve steam seals some time ago. Second photo left hand side is OEM style and right hand side is the new COMP Cams valve seal. Must use the COMP Cams spring locators also, seen in first photo (Black locator on "bottom" of spring).



August 22

Knocked a few things off the parts list on this order! Cam cover, rocker arm trunnion kit, valve springs, spring locators, valve stem seals, spring retainers, pushrod length checker and valvetrain lube.

January 27

New GMC front grill emblem. It's so perty.

Grill Emblem (12542030) - $75.72 - Dealer



October 12

Decided to put some character into the heads and splash some paint on them. Used a black ceramic paint, hopefully the paint will hold up to the heat. Dad also gave me some of his old analog meters and I found a perfect spot to show them off.



October 11

Dad bought me a couple neon signs for the garage. I also moved a 32" TV paired with a Roku. I haven't purchased anything recently for the truck but was itching to do something. Cleaned up the old 4.3 heads and inspected them. Sadly those are too worn to be used again.



April 03

Not bad for a newbie! This took me about three hours for one combustion chamber. Being SUPER careful not to scuff the valve seats. I used a combination of sandpaper cones from Harbor Freight Part# 62394 plus a Dremel with drum style sandpaper. After the power tools I followed by hand sanding with 60, 80, 120, 220, 320, 400, then wet sanding with 600 and 800. By this time it's stupid smooth and ready for polish if you want it. I wanted it. Why not?



March 28

Tested out a polishing kit from Harbor Freight (Part# 98707). BUT, before that is prep!! Sandpaper hands-on in stages with 60, 80, 120, 220, 320, 400. Then finally wet sanding with 600 and 800 (I don't claim to be an expert, I may be doing it wrong...but). This took about one hour because a flat surface is always easy. **KEEP IN MIND, this is just like polishing paint on a vehicle. If you spend too much time polishing in one area you will burn it. Keep a steady hand and move swiftly. I messed up in a few spots but you'll never see the mistakes haha** The Harbor Freight kit comes with Brown, Gray and White polishing rouges. This awesome chart found on Google below shows what else you can polish with Aluminum HB kit and what proper stages! And just like sand paper you want to follow the "color" rouge grits for polishing finishes. Fancy.



March 27

Cleaned the heads and look almost new!



March 24

I won't be using the factory springs from the 5.3 heads. Decided to use them to test a degreaser I mixed up. This is how one looked that soaked overnight. Looks fantastic!!



March 19

Disassembling the 5.3 heads and inspecting them. They are still in great shape.



March 17

Thanks to Brendan at LT1swap with his idea and guidance to keep the 4.3 harness and mate it with the 5.3 harness. This way the factory gauges, factory A/C, Cruise Control, etc. will still work. 5.3 harness gutted. I will wait til truck is together to route the harness and shorten/lengthen wires. I know for sure I will extend the new 5.3 fuses and relays to the storage box underneath the hood. I'm not satisfied finding a decent aftermarket waterproof fuse box, so that's where they will go. Check out September 26, 2020 post!



November 20

Cold winter won't stop me from buying new parts! Purchased all OEM trim, wheel arches and "GMC 1500" emblems. I was ecstatic that GM still offered the parts so I rushed to buy everything I needed before it's too late. This truck will look fantastic!!

Cold part of the year and finished in the garage for now. Truck wrapped up til Spring.



October 29

Wasted little time to get it on the stand and tear down.



October 22

HERE WE GO!! Picked up the 5.3

5.3 Engine with ECU and Harness - $650 - Local Seller



October 14

Gathered my Toyota and ASE patches to show off.



September 21

Purchased a cabinet to store chemicals. A fold out table to keep parts off the floor. Going to need room when I pick up the 5.3!



September 19

Found a 5.3 with ECU and harness for sale.



September 16

Was bored one day and decided to clean the firewall.



May 08

Starting to get crowded.



May 01

Buddies wife reupholstered my Harbor Freight stool for me. LOVE IT



April 29

Deterioration of cylinder walls and visible wear. 363k miles and WAS impressed to still see cross hatching in the cylinders, until I measured the cylinder bore. Tapered. Closer look at the crank, the rear crank seal was so hard (Never replaced) it cut HUGE grooves into it. Repair sleeve on top of the machine work just to keep the 4.3? 5.3 swap sounds like a better alternative like I originally planned.



April 28

Tearing down the 4.3 to see if it was worth rebuilding. Sadly, the engine is worn out. The OEM bearings are trimetal and you can see the wear patterns in them. On the third picture, the left most main bearing you can see a clear crack... poor engine wouldn't have run much longer.



April 22

Removed the exhausted 4.3



April 05

The truck survived the move and progress can move forward!



August 18

Same glass company came out to the house and replaced the windshield. It didn't NEED a windshield but the weatherstripping around it was in horrible shape.



July 19

Took the truck to a local body shop. Replaced rocker panels and cab corners. Fixed some damage to back window area and front bed panel. After that was done a local glass shop installed a tinted back glass. Perfect.



May 28

LS engine adaptors. New 5.7 clam shells to be installed on the adapters. New 5.7 motor mounts from an OBS to be installed on the truck frame. The 5.3 will be in perfect placement.

April 22

Passenger side of truck after graphics removed. Purchased a Trickflow flexplate spacer. Don't believe I will use this as I will now install a T56. Original plan was to reuse the 4L60 transmission that was original to the truck.

Trickflow LS Flexplate Spacer (TFS-30675700)- $79.99 - Summit Racing



April 21

I've tried and tried to find the same decals to install on the truck but was unsuccessful. Hour or so later with an eraser wheel they were removed.



April 06

Earliest photo I could find of the truck with the graphics on it.
