A look back to the heads installation photo_2021-03-01 22.13.29.jpeg photo_2021-03-01 22.13.33.jpeg sharp edges taken off in chamber with a sandpaper roll photo_2021-03-01 22.13.25.jpeg gasket i chose this one because it was thinner i think .030 as compared to something like the .045 Felpro photo_20...

photo_2021-02-22 23.49.50.jpeg Another view with the preemptive intake installed. The valve covers are also the older style because the later Vortec plastic ones don't fit over these 1.6 rockers and the way we did the valvetrain. I ordered these from eBay they are for a Marine 4.3 stock stamped ste...

photo_2021-02-22 23.49.55.jpeg I cut the EGR pipe off and went to a later intake. photo_2021-02-22 23.49.59.jpeg photo_2021-02-22 23.50.02.jpeg I used a bearing (5/8"?) to plug the hole in the exhaust manifold and cut the tube. Used the old hardware and chamfered the pipe part to mount it down...

Work, life, weather and everything caught up with me but the motor is ready to go in. I installed the intake on it and realized I had to take the intake off again so that I could install the engine into the compartment... the way it came out...with no intake... Updates and more details to come.

It takes TIME to build a motor! All the little things that can come up and surprise you. Had to order the timing cover and install the oil pump after welding the pickup tube in place. Welder broke so I got an exhaust shop to zap it. 66 ft lbs on the pump bolt. Day trip to drop welder off. Cleaned an...

After some research and checking, I ordered a Cloyes C3211 timing chain. It's twice the size of the one listed for the '99. Hopefully it all works because it is numbered for "up to '98" but it installed perfectly and the hall sensor pickup lined up properly. Here are some pictures comparin...

Cloyes has a high performance chain for balance shaft motor listed as C-3211 (Napa interchange: 103211) up to and including year 1998 https://www.cloyes.com/part-finder-single/?partno=C-3211&part_type=Heavy%20Duty%20Single%20Keyway&pl=High%20Performance&lookup=applicationhp&appmake=C...

Just doing some reading. I see that plastic runner... https://www.s10forum.com/threads/is-there-a-better-fix-for-the-timing-chain-rattle-yet.116300/ I never had any really annoying noise, it just sounded like a Chevy at idle with some ticking and was always reliable. Maybe I'll just run this timing ...

Looks like there is the updated cover and the updated tensioner assembly to install

Timing Cover - GM (89017259)

Well I just found this

99 balance shaft engine rebuild I feel like this replacement is kinda loose(r) than I'd like... anyone have any experience doing chains on balance shaft motors? Are they normally this loose? I remember doing V8 chains and those things are tight. The middle moves side to side about 3/8" but the ...

IMG_5445.JPG Installed the timing chain made by PBM Performance Products, part number T3212 It installed nicely but seems a little loose, about 3/8" play? The old chain is about 1/8" longer IMG_5447.JPG The 2004 Blazer manual I am using for assembly info has some sort of adjuster but mine...

For other engine rebuilds I would coat lots of motor oil on the rings and walls but this time I opted for a more clean and simple manner. There are many theories on the dry vs. wet piston install. Some people literally install them dry and coat only the skirts and pins. Some people use a thin coatin...

IMG_5443.jpg 1 @ TDC ; KB-193 pistons 4.030 The KB pistons require more ring gap on the first ring. It's because the alloy these pistons are made of transfer more heat and the ring landing is higher and closer to the combustion chamber. So if you leave them spec to standard, the rings will close up...

IMG_5411.JPG Had to retap the crank bolt to 12x1.25 metric. Long story short I used the old bolt to turn the engine over and I didn't use washers, instead I bottomed it out and it messed up the bolt end on the inside of the crank bolt hole. Hence removing it messed up the crank threads. I cleaned i...

Here are some other pics of the same work on the mains and dropping the crank in. IMG_5247.JPG IMG_5249.JPG This upside down pic views correctly if you click on it. The mains were torqued in stages 30-50-70 IMG_5250.JPG Here you can see the ARP bolts that have the washers; ARP sends some moly assemb...

IMG_5165.JPG Block all prepped and bolt holes chased (most of them anyway). I painted the lifter valley with a coat of VHT cast iron grey with the holes all masked off, and I tested an old lifter in the bores to make sure the new ones would fit and move. (not sure why this picture is 90* sideways) ...

this spec sheet was for the rod bearing bolts from ARP
