Thanks LT, it is nice to have you on here. Videos I can watch and I don’t have to turn the volume down because I am worried my kids will hear something they shouldn’t. That’s a rarity these days. I like that this truck is something not commonly done and has used a bunch of what GM had already built for these trucks. The best/cleanest builds implement as much factory stuff as they can. Keep it up, I send the links to these videos whenever you lost to my buddies.

Man i love this truck I’ve still got my old 2003 Silverado ext cab, it was my first truck after it was handed down from my great grandfather to my father and then to me I’ve never wanted to sell more or less for sentimental reasons even after the fourth 4L60 blew up it although i did have to get a newer daily driver truck but i didn’t really know what to do with the 03 either but watching you plant a big block in it gives me a bunch of good ideas for where i want it to go i grew up turning wrenches with my old man on his hot rods and it might be cool to turn it into a hot rod truck, man keep up the cool work i can really dig it

Awesome build dude. Love the Fab, and staying away from a remote mount system. My old man is a welder and always told me not to clean with break cleaner because it can react and release phosgene gas which is poisonous. Looking forward to the rest of the build!

[@LawrenceTolman]

thanks for watching! supposedly the non-chlorinated brake cleaner (the stuff I'm using) is safer, since it doesnt have the chlorine which makes the poisonous gas

[@StavTech]

Great video, you are a natural talking to the camera, very very pro. And the video is very informative about how you did it and why. Great work! And I agree about not remote mounting it, which is a bit ironic as two of my best known builds were remote mount turbo V8s, BUT when you got room, and you have, hell yes keep it under the bonnet/hood. I remote mounted mine as underbonnet would've been ridiculous work, more effort than it was worth, and the results were amazing. But do I think they'd be better if the turbos were in the normal position? Hell yes they would've been.

[@Finchweldingandfabrication]

small tip. argon is heavier than air so when you purge your part it is better to put the purge line at the lowest part, then poke holes in the top so the agon fills up the bottom and displaces the air out the top. anything works. this just gives a more efficient purge.

[@krishiatt7203]

Damn, LT welds up a nice exhaust! Well done brother, I think you have a bit of OCD and that's a good thing. Nice job man, looking forward to the rest of this build. Good luck with the sub's BTW I did my part.

With so much displacement I would of put a giant turbo So that there would be no back pressure issues also a camshaft something like a 212-218 and whatever lift you can fit in there on a 114 lsa

I felt like the S480 with the 1.32 AR turbine was a pretty good sized turbo which should also be pretty responsive with the displacement, and hopefully the 60mm gate will alleviate any possible back pressure issues.

I'm surprised you didn't bring up the minimum inner diameter of your oil drain fitting and an oil restrictor for the journal bearing Turbo... very crucial to the setup. I've gotten three "blown" turbos that just had way too much oil flow to them all I did was clean them up put them back together put a oil restrictor in and they worked great. Always remember 11 mm inside diameter from the fitting on the turbo to the oil pan cannot be any smaller.... .100 nitrous jet works well for an oil restrictor.

[@LawrenceTolman]

according to what I've read, on the S400 family of turbos, a -4 AN. (1/4" or 6.4mm) is adequate for an oil feed, with no need for a restrictor. And on the drain to the oil pan, I used a -10 AN (5/8" or 15.8mm). But you are correct, the drain needs to be as large as possible to prevent pressure building up inside the journal.
