Is it possible to switch to a wet sump system on a LS7 engine to make a swap easier?

And is there any OD tranny that can withstand the vigors and power from an LS7 engine? A standard 4L65E cant for sure i know

 

You can build the short-block with a standard short snout crank for wet sump if you want to. OR, I have seen a spacer that you can put onto the LS7 long snout crank that enables you to run a standard balancer off an F-body or Corvette. That's not my preferred method, but has been shown to be just as reliable in average street/strip use.

 

There's lots of info on this conversion if you do a search!

Here's a "Cliff's Notes" version.

Change to wet sump oil pan (several will work), change windage tray and oil pick up to match new pan. You'll need dip stick with matching tube (you get to drill block for tube).

Change crank timing gear to Ls2, change oil pump to standard type, change front timing cover to ls2 type (has crank sensor).

Shorten crankshaft (about 1" AIR) or have sleeve machined to push crank pulley back against crank timing gear. I'm told the crank can be shortened with a hacksaw??? However, if you've got the $$$ to buy an Ls7 why "shade tree" the crank snout?

You may (or may not) be able to reuse the Ls7 crank pully. If not, buy a pulley that matches your accessories (Camaro, Vette or truck).

4l80E (or 6l80E/6L90E) tranny should work fine with Ls7.

I suspect it's just as cheap (cheaper?) to purchase an aftermarket 8 qt. dry sump oil tank, tank breather and the required hoses. All depends on what you can get used. That is, assuming the dry sump pan clears and you have space to mount /route the dry sump accessories.

I'm sure if I've omitted anything someone will chime in!

 

Thanks.. Great info. It will be more "cool" to run a dry sump setup, and probably cheaper and certainly better so i'll try and forget i've ever asked

It is going into a c3 corvette. A 71 or 74 vert. Not sure.

Thanks for info
