moving ls1 engine across 60mm, need help with clearance questions?

hi all, have a bagged and bodydropped obs truck in the build at the moment and am sticking a lsx454 engine in the old girl to get her moving! now to my questions.

As the truck is now right hand drive (convertered for australian compliance) the exhaust headders are going to be very tight due to the steering column shaft. From factory the engines sit closer to the rhs (i would say for steering shaft clearance on lhd models. Now my plan is to move the engine towards the lhs about 60mm (2 1/4" roughly) as that will be perfect then and solve my clearance issues there!. Now my only issues i now have are.
1) will moving the engine this much cause me clearance issues with the sump hitting the engine crossmember?

2) i plan to put a 4l80e behind the engine, do you guys think i am going to run into issues with the trans hitting the floor/tunnel? i also i realise i will need my diff built to suit how much i move the engine across also but thats the easy part!

would appreciate any advice! As i have no sump on my ls1 mock up engine or a 4l80e trans at the moment it obviously makes it hard to know what effects it will have without being to see in before i move the engine! Also what would be the best sump to use for my truck, need something that is going to be suitable for a truck that is going to be (driven hard/thrown around so to speak) cost is not a issue when it comes to getting the best possible sump also, so if i could get a link to a good sump that would be great also thanks ryan!

if you have the tools to bag and body drop, why not just modify the crossmember if there is a clearance issue? and if you are body dropping, you will probably have to modify the tunnel.

Use an Fbody/Camaro oil pan/windage tray/pickup tube assembly in 88-98 model trucks for the best clearance. With the engine in the normal location the 80e is no issue with clearance. Moving to the left could cause issue but nothing that can't be fixed with a saw and welder. A column mounted shift linkage could be tricky unless you do it via cable instead. Floor mounted would be straight forward other than twisting the lever to RH drive ergonomics.

cheers for the replies fella's. I wanted to avoid modifying the tunnel but i guess i will see how i go! As for the shift linkage set up i plan on running a cable instead of the way i have it now with the linkage set up anyways (will still retain column shift though). With the sumps is the stock f body one the one to get? i have a link provided to the stock one i think?

With the stock sump what is the depth of the pan it's self? have googled but cant find the answer!!
was looking at getting something like the moroso pan (link provided) that is 6" deep but not sure if it will sit lower than the crossmember!

anyways thanks for the help so far, appreiciate it!

The dimensions are over on www.hotrodlane.cc

I got my conversion oil pan from this guys......

Perfect fit !

cheers for the replies guys!! 2boostedsilverado, do you think the 5 1/2 quarts oil capacity for a lsx with power figures around 700hp at the flywheel? will be a n/a lsx 454

Mine is close to those specs you mention (700+hp) and have that oil pan !

Ok cool, have you actually driven the car around with that engine? can i ask who built your motor? and also you running auto or manual behind it? if auto what size stall you going with?

No
Yes (Mast Performance)
Auto
3000 stall

nice im getting a mast performance engine also! but from shafiroff, seem like a good value for money engine in my opinion!

I got it form Nelson Performance !

Is a nice engine, for a DD project.

For the same money I think you can get engines with more power if racing is your goal.
