I'll check in with Circle D right now.
OK, checked in with Chris at Circle D, he's a guy who knows his stuff. He sold me on the 3-disk 10 1/4" converter. I'm going with a 2600 stall. He's putting the billet LS front on it to go with my heavy flexplate and ARP bolts.
Now to order a Transgo kit.

Guys, I changed the title of the thread. The thread had outgrown the title and I wanted to describe it a bit better. For the mods, if you'd like to throw this into the projects section, go ahead.
I don't know why they don't recommend the smaller converters at PI but the guy seemed pretty set against it.

As For Precision Industries, always always ask for Terry, the owner, dont talk to Jack.
Terry is the guy who specs my converters and spec'ed me a multi disc vigilante 10.5 converter that will work great with my blower and still be able to tow if i want too, but thats what the Dmax is for
Just posted above info for any future guys who might talk to precision, thats stupid that the guy told you 13.5 converter and such.

I'm pretty excited about the converter, it looks like an excellent product from a great company.
I was messing around with the 8-rib pullies to see if it was all there. The tensioner might need a bit of shimming and the power steering pulley jammed up when I pressed it all the way on. I had to back it off a bit. That concerns me a bit.
Does anyone know how to remove the power steering pump? I got the four bolt up front but it still won't go. I think I'll change it as it looks to be seeping some oil.

Late to the game...
I agree. A few reasons I built a 383 over a 408 were:
1. I already had the heads. They would have been too small for a 408 and too big for my 5.3
2. I didn't want to max out my blower. It's more suitable to a 383 than a 408.
3. I wanted some semblance of fuel economy. This is the truck I commute with. It's a short commute but I do drive it around town.
4. the 5.3 blocks are so easy to find, and cheap. I got the whole engine for $200 and have sold a few parts from it to further offset the cost.
5. Everyone's doing a 408. I know it's an excellent engine but I like the size of the 383. It's halfway between the 6.0 and the 408 and it's different, especially with a blower. Not many guys have done one.
6. It will have some awesome torque, bar none. Especially if I upgrade to a TVS2300.
I know there aren't too many good reasons for building a 383 over a 408 but now that I have it I'm glad I built it. There's a kid in a town nearby that I know and he just built a 383 Vortec for his '98 4x4 Sierra. He thinks he'll have a good chance against mine even after I'm done the swap. It's a nice truck, but boy is he in for a surprise this summer.

I have a 408 in my GTO that I would love to bolt into the Yukon for comparison, but (for me) that's just too much effort for "reference purposes".

At the time he was not a fan of the stroke being larger than the bore when combined with the positive displacement blowers
Did some more work this morning. Took a break for lunch. All I have left is the headers on one side and the hood. Then this sucker is out.
I had some good luck last night. A guy came over to buy some O2 sensors and it turns out he's somewhat of an expert with HP Tuners, He's going to help me set this thing up and get it all dialed in. He's also going to help me with the crossmember mod. He only lives 5 minutes away! Too lucky.

The old 5.3 is out:
I went to install the valvesprings on my new heads and ran into a problem. The new bronze valveguides are wider at the bottom and the valvespring seats wouldn't fit. I guess I'll be looking for a set with wider holes in them. Maybe I'll call Patriot and see what they recommend. Otherwise, I can put this engine together and get it in:

So how much boost do you think you will make?
I know our engines are different, but i might be looking at the IW OD pulley to add more boost. Just wandering what 10% OD equals in boost #'s. I 'd like to see 12# with my 2.85 pulley and the IW pulley.
