Default 106MM 347 in a GN build thread

Here's a few quick shots... I'll post more when the headers come back from the polisher.

Stock LS1 block and crank with a cleanup hone and Eagle/Mahle combo
Ported 317s with GM MLS gaskets, stock diam. studs main/head

400 with a brake and NC converter

Turbo system- 321 double slip merged headers, 3" crossover and 5" DP

This is just a "get it running" engine to be replaced with a Warhawk later on.

Did you custom make your mounts and crossmember? I am gathering parts for my TT 402 L92 GN build and just trying to find those parts before I have to start fabbing them myself .

Oh man, Im gonna have to keep an eye on this thread. Im looking at parts now to do a 370 single turbo in my GN. I was just looking at the OFI 98-02 kit. The headers and x-over look like they may fit the G Body chasis. What are you using for headers??

89WS6, I have heard that the Fbody headers will fit into the Gbody without any mods. I havent tried it myself, but just what I have been told. On my TT, I want to retain the AC and I want it to fit to my specs, so I am custom making mine. Have you looked into motor mounts and a crossmember. Just wondering if anyone is making one, or am I also going to have to fab that up?

It's got custom solid mounts with custom merged 321 headers. They're being polished right now.

There are mounts and a x-member available. Im at my sisters but as soon as I get back to my place I will post the link. Im also thinking of using a 4L80E which I already have. I have a TCI TH400 with a JW Ultrabbell also but Id like to have OD back. I also have a FAST on the car now but thinking of selling it and running stock PCM with LS1edit or similair. I would like to make 700-750rwhp, using a single PT88, right now Im at 554rwhp on my v6 @ 22 psi on 93 and alky. For now, I maky get a 4 bolt housing for the T70 I have until I can upgrade to the 88 since I have the 70mm already.
