What year are those manifolds? I don't know the part numbers off the top of my head. I have a couple sets of Zo6 manifolds at the shop. I can get you a pattern or just shoot you some dimensions. Shoot me a PM and let me know.

Not sure if this has been addressed, but the schematic for the S&P style motor mount plate is incorrect. The countersunk hole should be the second from left along the upper portion of the plate, rather than the second from right. See S&P's installation instructions (second photo down on the left shows the countersink well) for clarification.

The LM7 was available from 1999-2007. It used a Gen III (like the LS1) ECU. There was a good article with descriptive pictures of the different ECUs in GMHTP magazine. You should be able to identify your ECU by going through this article with a fine tooth comb:

Good luck.

12sec ss, Would you happen to be able to get the wiring diagram for a 04 z71? It has a 5.3l. If this is possible it would be greatly appreciated!

Thanks v v much.Iknow now i have 99-00 blue and red connector ecm.ihave reworked the harness.How do i delete bcm/vats.read somewhere cant use the 555 method i pulled on the lt1 95 obd1. Also i have no maf sensor somehow i want to delete that too,as well as the 2 o2 sensors at the back. Also egr and other peripherals.I looked alot on inet but didnt find the right info.Want to do it myself on shoe string budget otherwise all the fun is gone. I am also looking for a optispark optical sensor and slotted wheel.Want to try and make a lt1 HEI big cap dis to run the orginal pcm.Also needed is a obsolete lt1 waterpump to be converted to electricl.I bought lt1 without dis and wpump to get the intake for a sbc intake swap but saw the lt1 was overhauled.Thougt it would be a sin to just let the lt1 go to waste. Prepaired to pay for plus shipping. regards abi

To delete VATS, you have to turn it off INSIDE the PCM through either HPTuners or EFILive. To delete the MAF sensor, you would have to get it tune to Speed Density Mode, (which also requires HPTuners or EFILive); this isn't really recommended for a car that sees all types of weather though, due temperature differentials. O2 sensors, EGR, and the like are the same deal; turn off DTCs in PCM, and delete from harness.

2SEC SS, if you have the chance, could you potentially post the diagrams for a 99 GMC K2500 with a 6.0L / 4l80e / NP241HD? Dunno if there are any differences between it and the others posted, haven't seen any wiring diagrams for a 99 truck yet...

The truck is the new body style, never put a 350 in them as far as I am aware

The door sticker says 03/99 for the build month / year

I'm not sure which letter indicates the engine code, but the VIN of the donor truck was 1GTGK29U8XE53xxxx
