98 V6 to LS1 Swap

[cade75]

With a 4L60E on the V6 woud I be better off changing the bellhousing and input shaft or just getting a 4L60E off a V8 for this set up?

There's no difference in the 4l60e between the two v8 or v6 other than bellhousings.

Any info on the oil pickup tube, from comparing the pans it looks like I would not have to change it but I am not sure.

Yes the oil pan will be different as well as the pcikup tube. If your dead set on getting a motor from a truck (nothing wrong with that) try to get an lq9 6.0 found in escaldes, denalis etc rather than a 6.0lq4. The lq9 came with a higher compression ratio an full floating pistons (the lq4 didnt have them until 04 iirc). The price difference in the engines shouldnt be too much. Also the wiring harness, pcm, front accessories, and intake are all different in a truck and you will need to find these from an fbody to complete your swap i suggest you browse ebay or other boards and classifieds to find them. Its a little easier to just buy a donor wrecked fbody because that way these things wont nickel and dime you to death but I cant fault you for that lol it looks like a cool build.

The trannys WILL NOT work sorry, the v6 fbody tranny uses smaller clutches and valve body routings for the v6 and will grenade pretty quick behind an ls1 not only that but the input shaft and torque converter are also very different so it wouldnt even work even if you got rid of the bellhousing. To the OP when your at the yard see if they have any 4l60e's laying around from the v8 trucks any of those should work nicely.

Nothing to be sorry about you are correct.. I dug into it a little futher today and they are in fact different.

I am sad to report due to some financial issues the family member I was getting the car from has found a buyer for the V6 camaro. I am not to upset because they need the sale, and I was getting it for free. I cant tell everyone how much I appreciate all the advice and tips this has been the most help I have every recieved on a site like this. I am going to save what I have aside and I am hoping that it will be in the near future, but if not I will be sure to check in and post the buy. Thanks everyone.

Hope it works out for you. Lots of good clean F-bodies still out there for the picking.

I’m looking into doing a similar swap but but having trouble finding an aftermarket kmember there’s so many… any help???

If you're going with aftermarket you can't go wrong with UMI Performance K member. As much as I praise UMI I'm not sponsored (unfortunately). I just love their products. Worth every penny, quality and fitment is top notch. I didn't have to resize holes or make header clearance like some of the other choices out there.

If you get one, some pointers if you're going to do it yourself. Harbor Freight sells an engine support bar that will make this job so much easier. Be prepared to replace your bushings if you're reusing the stock upper and lower a arms. In fact I strongly suggest you do. Chances are they need to be replaced. Lower stock k member slowly becomes there's hidden bolts that the brake lines attached to that you need to free up. The rack and pinion - flip the bolts when you go to install them. It makes it easier to take it out in the future when it goes out. Otherwise you'll have to lift the engine to get the bolt out.

Also this is a great time to update/upgrade the engine mounts. I recommend going with poly over stock.
