Some random picts of stuff I have that I will use on this project first is the original turbo 400 trany I had that bolted to the np203

Here is the adapter that bolts the 400 to the np203

Some picts of the 203 low range portion that will be used in the doubler

Here is the adapter that bolts the 400 to the np203

I sorry, but that adapter is for a T350/NP203, not a TH400.

The big block that will be going under the hood

Mickey thompson valve covers elderbrock intake hooker headers and mufflers Holly carb

The 14 bolt that will be going in still needs all the work

The bucket seats that will be going up front on top of my captin chair brackets

The 38x12.5x16.5 Tsl's that will be The blazer's first set of tires I hope to be able to run 40-44 when I'm done

Trying to figure out what gearing this 14 bolt has here is a pict you can't see the #'s well but here they are. crap I left it at the shop so I won't be able to tell you what the #'s are till wed. I think they are 4-10 or 4-11 any help would be great

The 350 I pulled from the truck I got from the junk yard

The turbo 350 and 203 that came out of the blazer both should work for sale$$$

Ok that's all up to date and now I'm off to bed

I assure you that that bracket bolted together that turbo 400 and that np 203

 

[joecowap]

Are you 100% positive. Beacuse in the previous pic your turbo 400 has a round six pattern which all turbo 400's have and your adapter is the square 4 which is what a turbo 350 and 700r4's have. UNLESS this adapter was a weird adapter that only used 4 of the 6 holes on the tranny. Is this true or did you take a pic of the wrong item??

May want to double check this. Unless you're a magician, these two parts have no way of joining together at all:

I think he may have an advance adapter kit. He is not showing us a piece.

Awesome build! I'm jumping on board. That Blazer looks like it was originally Lime Green, just like mine...and Gus'...and Colby's...hey it's a popular color.

 

[74Chevy454]

Well today I didn't get to mess with it any I was going to cut out some bushings that are stuck in some lift springs that I baught a while back so I could get some new poly bushinhs on order. I also wanted to put that adapter on the tranny and T-case I know they were together at one point I think there might have been another ring I'll see and I'll let you guys know and get picts and correct myself if I'm wrong. I got in my 3" body lift today I know I could have just made my bracket's 3" higher but I have them now so i guess i'll use them. I found my pad also that I wrote down the #'s from my gear so if any one can tell me what gears I have that would be great the #'s looks like 21 GM 3977334' 10 41 1 8C So what does this mean?

 

[y5mgisi]

Should be 4.10's.

 

[74Chevy454]

Ok so for S&G's I went out into the garage just to see if the adapter would directly bolt the tranny to the transfer case and you guys were right the adapter is not a direct fit I believe there is a collar thar bolts the adapter and the tranny If I can find it I'll post picts I think I still have it sitting around. Here are some picts of adapter and other items that will go in the blazer

other parts

Today I ran some first pass welds I only got one side welded now and I also found the adapter that bolts between my th400 and the adapter to the 203. My camera was not working today so I don't have any new picts when i get it working I'll post more picts.

With a stock frame with Kert's B-52 kit or relocated factory spring mounts, you would need a 2" lift rear spring to get 6" of lift in the front. I don't know what you going to need with your custom frame.

Edit-here is a thread with a lot of info.

I take you have this kit then.
