Great information! One thing is the engines out of the Envoy,, Trailblazer an Ascender that had the 5.3 LM4 engines had that power steering pump not just the Trailblazer SS. I suggest that you replace the rag joint while you are at it.
your engine mounts must sit high or something for the pulley not to hit. Hell my whole damn pump is sitting on the box atm so im going through a bunch of videos trying to find a solution lol but its gotta be the ebay mounts I got. Ive got a 05 5.3 envoy engine that already has the smaller pump pulley but I had to pull the reservoir off it just to get the engine in. Using a knock off holley pan from ebay, clears the frame nicely. Fired up the engine on the ground. Seems good, but ran into issues with the dod due to the second pressure relief valve no longer being in the pan, think ive got it solved atm but ill find out for sure once its in the truck. not in the position yet to delete the dod but itll be getting yanked after the truck is driving for a bit. Cant wait to see how this thing moves tho, its a cheapie build so I got some fb marketplace corvette wheels for it so it has a little more meat. Still gotta do something about the open diff. Hopefully can get a posi carrier at some point but I liked the gearing in it with the 4.3. Sounds terrible but it has 2.73 but it was a perfect match up with the getrag 290 factory 4.3 tranny. That 4.3 would get it one wheel peelin easy so the 5.3 is gonna be spin city, likely even with a posi. the envoy 5.3 is all aluminum aswell and lighter than the 4.3 it replaced so the truck will be lighter and much more powerful. Weird crossover 5.3 being an lh6 still 24x like gen3 so I can keep cable throttle but has the flat top pistons and stronger rods from the gen4s.
Yeah I'm always on the lookout for the early aluminum 5.3 24x motors, not many in the junkyard but I still find one a month or so. One of the reasons my pulley cleared is I angled the motor back a hair more then normal, just lowered the transmission mount a little which raises the front of the motor up.
It's the stock location. The holes I drilled in the pulley are so I can un-bolt the pump without removing the pulley. Normally you have to pull the pulley to remove the pump, then press the pulley back on, down in the engine bay when re-installing. This just helped with future maintenance since GM decided to not drill holes like they did in the past.
2001 tahoe 5.3 into a 1987 2wd s10. I used stock 2.8 frame mounts with amazon block brackets. The stock PS pump and bracket for the 5.3 and changed the pulley to a dorman 300-202 and its about 1.5in smaller than stock pulley. Will clear steering box
I didn't check the balance, but with opposite of center drilled holes done on a mill I wasn't too worried, it's been working fine and hasn't wrecked the bearing...yet. Good to know the Vette accessories and holley shaft work also.
I read that too, but in the end the stock S10 steering shaft worked fine, but I'm using modified TBSS manifolds instead of headers so I have a little more room then normal.

Thanks for the info!
What kind of engine mounts?
what engine mounts did you wind up using? Love the videos man, giving me lots of motivation!
Poly mounts from Chi-nah.

I’m confused. What did you do to modify the power steering pump location? I see you’ve drilled the holes but is it still in the same oem location?

@@wilsworkshop noted, thank you sir!
Love the videos keep it up
What is the exhuast manifold you use ?

I used the 2005 Vette Acc and holley steer shaft! Did ya check the balance on that pulley after drilling it?
I didn't check the balance, but with opposite of center drilled holes done on a mill I wasn't too worried, it's been working fine and hasn't wrecked the bearing...yet. Good to know the Vette accessories and holley shaft work also.
If the stock 5.3 pulley does not fit I'll just use the 2.2 pulley. I'm not to worried about spinning the pump a little faster.
Jeep steering shaft
I read that too, but in the end the stock S10 steering shaft worked fine, but I'm using modified TBSS manifolds instead of headers so I have a little more room then normal.
