Re: Doing LS Swap - I have no idea what I'm doing!
Yup! are you setting in for good or are you pulling it back out? I'd get the old broken hardware out of the head before putting in chassis for the final time.

What broken hardware are you talking about? |
Re: Doing LS Swap - I have no idea what I'm doing!
I think he's talking about the broken exhaust manifold bolts. Those are way easier to do outside the truck.

Yup, was referring to the broken manifold bolts still in the head, much easier to work on with it in front of you, not sprawled out in an engine bay. .

So, went to measure my frame rails last night. This never even registered that something was different. But, I realized that the frame rail has been "adjusted" to make some clearance. Don't know how they did this, or why, but maybe it'll give me some room to keep the a/c?

Yep, I'm pretty sure that bend in the frame is for fuel pump access on original engines, they're all that way.

OK. Good to know. Thanks, guys.

Re: Doing LS Swap - I have no idea what I'm doing!
Looking at this oil pan kit from Jegs: https://www.jegs.com/i/GM+Performanc...QAvD_BwE#qaTab
Anyone used it, or know for sure if it will fit in the trucks? |
Re: Doing LS Swap - I have no idea what I'm doing!
I would set my engine in place first and see how low the truck pan hangs down then look at pan dimensions to see what will fit better
Placement how far forword or back and how high the engine sits will all play a large factor on which pan you will need Give two strangers the same c10 and the same ls motor chances are both trucks will have different placement of the engines needing different clearances for the oil pan |
Re: Doing LS Swap - I have no idea what I'm doing!
Well, by my estimates (took some rough measurements last night), the current pan drops below the crossmember about 2.5"-3". Now, a normal truck height, that might be ok. But, my truck is lowered 3.5" in front, 5" in the rear.
I don't really want to put the motor in to see if it will work, then have to take it back out and order new parts. I want to have it ready to go, install the motor, and be done with it. I'm borrowing an engine hoist that I need to get back to it's owner, and have to have help and/or guidance putting the motor in. |

Here are snapshots from a post I read on facebook. I think I am going to go this route on my swap. |

Re: Doing LS Swap - I have no idea what I'm doing!
from what ive been reading, the Cadillac cts-v pan is the best bet for lowered trucks. thats probably what i will end up using since mine has air suspension
|
Re: Doing LS Swap - I have no idea what I'm doing!
The other good pan is the holley pan or its fleabay knock off lots simaler to the fbody pan but the sump forward is shorter
The muscle car pan is deeper then the fbody pan Personally I will set it in place and order from there or just go with the holley pan which is like the fbody pan 2.0 |
Re: Doing LS Swap - I have no idea what I'm doing!
The f body or one of the holley (or copy) swap pans is your best bet for fitment. I don't know who said the CTS-V pan was best, it's almost an inch deeper than the F-body. I'm pretty sure I've posted this here before, but here is a great link with all the pan dimensions. https://www.improvedracing.com/gm-ls-oil-pan-dimensions

Re: Doing LS Swap - I have no idea what I'm doing!
The CTS-V pan is closer in physical shape to an old small block, thats why it fits well. The F body pan, while not deep, has a very long sump which requires the engine to be set back further.

I stand corrected.

I just didn't want to have to shell out any more money. But, I guess that would happen if I bought the wrong kit/setup, then had to change it out for another one due to it not fitting, or hanging down too low. |
Re: Doing LS Swap - I have no idea what I'm doing!
Is removing the front end an option? Otherwise I'd say plan on pulling multiple times for clearances. There are some patterns forming here that you should avoid. The truck pan will work, avoid buying parts ahead of time and you're going to spend more money than you wanted. That's just what it is. Set it in as is then identify what you'd like to adjust. GET IT IN AND GET IT RUNNING. This is a really simple swap for these trucks, don't go making it difficult.
