first, thanks to all for answering a ton of questions just by me lurking on here and searching topics. i've got an 84 olds cutlass that i'm swapping an ls1/t56 into. my question to all g-body t56 guys is does anyone have any pics and/or tricks on installing the clutch master cylinder in the car. i have the whole clutch setup from the 02 T/A donor car. i've installed a borg warner t56 in an s-10 years ago, the clutch setup is similar to the tremac but there was a ton more room in the truck. thanks for the help.
I bought the one that jegs sells call their jegster for a g body with a 700r4 trans only because i wanted the dual cutouts for dual exhaust but i had to modify it to fit. I cut both mounting tabs off the ends where it mounts to the frame and made new ones. This was mounted on a 86 elcamino with a 4l60 trans and john b engine mounts.

can you post up some pics of the modifications you did to the crossmember that would really help I like the cutouts for the exhaust to thats why i wanted to get one like that ive seen them retail for $300 how much is it for the jegs crossmember
It cost lest than 140.00 at jegs. I would have to pull it off to show you any pictures. The mounting holes did not line up and i had to extend the mounting flanges that they had. Maybe because of it being a elcamino or because of the location of the engine mounting. I did not even try the stock one because i wanted the dual cutouts.

RE filter [QUOTE=81cuttysupreme;13487569]is anyone here running a corvette style fuel filter/regulator? If so where did you mount it? And what kind of connections did you use? Do they come with the GM quick connections? How do you convert these to AN fittings?[/QUO
Just did and LS7 '78 Monte. Use the Corvette filter/ regulator. The plug in factory style filter lines are availible at any parts store (got mine at NAPA) and ther are about 3-4 inches long. You will then use a compression union to AN fitting ( 3/8 and 5/16 availible from Street and Performance) Mark at S&P also sells the whole filter, fitting kit. Just plumb from there with AN fuel line. I used braided. Mounted mine on the rear crossmember between the coil springs on the front side. Easy setup.

fuel pump i have a walbro 340 and a grand national sender and tank. i'm trying to figure out how to wire the pump now. i ended up putting the regulator on the slanted part of the bottom of the trunk. off to the driver side of the pumpkin. i just hope the exhaust wont get too close to it.
speaking of wiring does anyone have a good source for information for wiring help. i'm moving my battery to the trunk in addition to the conversion. i need some diagrams or some type of wiring for dummies.

Hey guys. This thread is going to be my bible over the next few months/years. I currently have a 5.3 LM7 motor that i'm going to be in process of building up and swapping into a g-body. It came with none of the front accessories, my question is what accessory drive systems have worked on gbody swaps?
Keep in mind the important fact that i'm going to be deleting A/C, so i wont worry about mounting a compressor or having to re-locate it due to its position. I've heard that the compressor is really the hardest thing to get past- so if that's gone I probably have any option available, correct? (depending on what intake i want to run, obviously)
What about the aftermarket as well- i've searched around and have heard about LSx swap accessory kits, but haven't seen them online anywhere?
Thanks in advance!

truck manifolds flipped clearences? I read alot about ppl using the truck manifolds flipped foward for budget turbo manifolds, does anyone know if they will fit in a gbody? I know they fit in the tighter engine bays of the 4th gen f-body, so i assumes it would work in the spacious G body bay, but does anyone know for sure?

lsx gbody swap I've got my eye on a lq4 6.0 motor from a 2005 escalade. I want to put in into my 86 Olds 442 and mate it to a t56 6 speed. Am I nuts to undertake this? It would be soooo much easier to put in another 350 which it already has. Any forums/links on this swap? Thanks

I have custom mounts and I using a 4l60e transmission.
The engine mounts are custom made but I have also used the "re-locator" plates that are commonly out there, that are supposed to put the LS engine in the correct "small block" position. Here is a pic were you can see the "plates" and the mount
here is a pic of the oil pan from the front
