Ls engine and 6L80 transmission

[Driftcutlass]

Hi every body!

I am pretty new and wish to swap my Cutlass supreme Classic Brougham 1988 steering column shifter with 307 Olds and 200r4 to a 5.3 vortec aluminium with all injection system and a 6L80 transmission.
I plan to change the cam, put short headers and appropriate intake.

I am wondering about the wider of the 6L80 and the trans tunnel of that g-body, will it fit? The speedo of my olds cluster will work with? I bought another car with the floor shifter console, mine is steering shifter, I don’t know which one use?
The rear end is 3,42:1 ratio and the wheels size is P245/60r15

I am wondering if that set up is possible with that G-body space
I like the overdrive ratio of my 200r4. I think the 4.02 ratio of the first gear of the 6l80 would push the car very well. I surely forget many details and will be glad of any help and council of those who can give me some input
Thank’s in advance and best regards

Hi all,
On a 5.3 liter, if we remove the engine truck oil pan and put a G-body one, is there gonna have less oil?

Can we find a G-body special bellhousing for a 6L80 transmission or the Silverado one fit it well?
Any comments?
