The G-Body Swap Thread
whew, read this whole thread in one night, was making a list summarizing what I need for a swap, helping with a 1980 El Camino build.
Seems the elk needs the 1992-1994 Roadmaster tank, factory sender with upgraded pump?

Tank is the easy part, but the 4.3 injected sender seems impossible to find. The Wagon seems to have the other problem, the sender is made, but the tank is off the market, but I can at least find a few of those in a salvage yard. My understanding is it is a bolt in, but the filler neck is a smaller diameter than the elk and will need some fabrication there.
But if you have any ideas for the eco tank instead, I'd love to go that way! The universal TPI conversion setups are about as expensive as a tank.

Not sure what the deal is with the drivers side but it don't line up for ****! I don't know if they're supposed to line up like this but i wouldn't think so. I've seen a couple pictures of the Spohn mounts but they are always the passengers side and never the drivers side.
well still waiting for my power steering set up i got the engine (2010 LS3) mounted to a th350 trans that was in the car from before the swap. I used the hooker/holley motor mounts(part#12643HKR) that mate to the stock clam shells which the instructions tell you to move rearward to the next mount holes in frame (picture shows the oem mount spot) im curious if any of you have used these mounts from holley and if this looks to be the amount of room you have between the rear of the block/heads and your firewall (pic shows the amount of room i have) seems too tight. trans dip stick tube has no damn room to go where it normally does. that aluminum plate covering my heater box opening is about 1/4 inch thick as well
seems to me the original clamshell mount holes would be better my oil pan is miles away from the frame so theres room there and tonnes of room up front for fans /rad/ etc so..... let me know people thanks

also the holley g body ls swap trans crossmember is not even close to lining up with the trans mount bushing on the th350 trans (came out of a 78 monte)
one thing after another with this damn swap haha

The Hooker G-body crossmember was not designed to work with a TH350 or 700R4 transmission.
The engine inclination angle has a profound impact on the clearance between the cylinder heads and the firewall; what crossmember are you using to support your TH350? That could be the cause of your problem and may require you to use shims between the crossmember and trans mount. You'll want to investigate that in conjunction with checking your U-joint working angles. As a quick-check, you can eyeball the relative angle difference between the bottom surface of the trans pan and frame to get an idea of where you're at...if the bottom of the trans pan is level with the bottom of the frame, or angled down in the rear compared to it, then you will have the clearance issues you are describing and your U-joint operating angles will be non-optimized.

just read the other message haha so there is no way this holley crossmember will work with the th350??????
and i plan on running a built th400 but i cant afford it right now so was just going to use the 350 to get the thing moving the harness ive had made by psi is set up for the th400 not a 480 or 460le so.....

so i broke down and ordered the holley ps pump resivoir kit and idler pully as they were cheaper than an 06 vette by quite a bit and they are designed for the bracket i hope they work!!! probably need another installation kit for them haha

The Hooker crossmember will not work with a TH350 in any configuration; the mount location on the TH350 is more than 5" further forward than that of the mount location on a TH400 or 2004R, which are the same as a T56 (within 3/16"). What year/model is your car? The 78-up A-body/ Malbu cars have proven to have tighter clearances at the firewall than the G-body designated cars for some unexplained reason.
