I finally bit the bullet and started an LS swap on my 1974 260z! It's been a little nerve racking wondering if I'll be able to get it all back together. This is my first major undertaking, and first build where I'm really putting some time and money into the project rather than skimping, and doing little mods.
I've had several mis-starts, and am now trying to keep it simple. Get it on the road, and then refine things as I go. I bought a t-56 out of a CTS-V, but then realized it would take too much to convert. I recently purchased a 2009 6l ly6 and 4l80e that I've decided to use. After receiving it, and doing a little more research, I discovered that those transmissions are quite a bit bigger than their little brother the 4l60e, and so I've been contemplating switching to the 4l60e. Ultimately I decided to stay with the larger transmission because of the cost of buying a custom/alternative ecm to run the engine and different transmission.
I pulled the original datsun engine/trans, cleaned up the engine bay, used my Dirty Dingo ls swap engine mounts, and got the engine mounted in the car! It looks awesome! The only problem is that
1. I bought the wrong oil pan off of Summit. It ended up being 8" deep which was way too close to the ground. So I'll have to grab a new lower profile oil pan.
2. More concerning is even the transmission oil pan is really close to the ground!
The trans oil pan sits about 3.5 inches off the ground. I can tuck the tail up a little more, but ultimately the pan heigth is tied to the height of the engine, so I'm not sure what to do there. Does anyone have any thoughts? The car has been lowered, but not excessively. I'd guess the frame rails are 6-8" from the ground.
I plan on putting the ECM and fuse/relay block near the firewall where the clutch cylinder was.
Toward the bottom I have some pictures of the clearance issues. Thanks for any help you're able to give!
