Along with checking Rod side clearance.

Cam installed and being degreed in to verify cam timing is correct .
Also time to check PTV( actually did this after the 1st piston was installed although I've done enough camshafts now to know this cam would fit beforehand)

Next up timing components along with the lifters and lifter trays ...

Time to add some heads . We used a Cometic .045 thick MLS gasket on this build. A OEM head gasket would have been cheaper, as these are overkill, but I wanted to set the quench at .040" since the pistons sit out of the hole .005", and there are no GM gaskets that thin.

Didn't get pictures of the oil pan and timing cover installation , but we just used the old stuff after some clean up of course. Time for the removal of the original 5.3 and the addition of around an extra 150 rwhp !!!

Engine back in a finishing up a few odd and ends ...
Added a later model L96 truck intake and 50lb flex injectors in case we wanted to go with E85 fuel down the road .
We also ended up adding a Circle D 3200 stall speed and some 1-3/4 ; headers, Y pipe w catalytic converter delete pipe . We also used on of my Borla mufflers for some added airflow and louder HOT ROD sound of course .
Doesn't look like 500+ hp now does it

We could have use the Sunnen to hone the block but I wanted him to get the real hot rodders low budget experience like I did back when I was 18 and had no money ...
So a brush hone and some cylinder lube and here we go ....

The ol “dingle ball hone”.
