Which oil pan?
 

I've got a new project. A 68 SWB fleetside with a 5.3 LS engine in it. The stock oil pan is too low and I'm planning on replacing it with a Holley 302-1 or a 302-2 or something better if there is one. Anybody have any ideas?
Thanks.

Re: Which oil pan?
 

I cant answer your question but Im going to move this to the Ls section for you. The guys there will be able to help you out.

Re: Which oil pan?
 

The H3 pan may be a ton cheaper and I know the S-10 guys are using them for that type of truck so it should be plenty for yours. Jim

Re: Which oil pan?
 

The f body pan was $300 to my door. Read up on the Holley pans, you need to modify the windage tray which scares me

Re: Which oil pan?
 

Thanks... I'm not sure where to ask this.

Re: Which oil pan?
 

ooops

Re: Which oil pan?
 

What is the H3 pan?

How low is the F body pan in a 68?

Re: Which oil pan?
 

The "H3" pan is another name for something called the LH8 or "Hot Rod" Pan. Allow me to expound: The Hummer H3 got made for a few end-run years in a model called the Alpha, which replaced the 3.7 5cylinder with a setup for the 5.3 but still retaining hummers AWD system. When GM did that version of the truck, they approached it much like a hot rodder would, and simply went into the GM parts locker for a solution.

GM had started selling crate motors and replacement motors by that time, and they had an existing part # in their "Hot Rod Swap Kit" which, sure enough, just happen to be the SAME pan that fits the Hummer. For most purposes, its the universal solution.

It WILL still hang about to crossmember level, but not below, and clear the crossmember just fine.

There are multiple sources, but searches for "GM Hot Rod Pan, LH8 Pan, or H3 Alpha Pan" will all return the same part #'s. I suggest checking places like Nalley (which sells GM part #'s for a few $$ less than most local dealers and no tax).

Could always look at ebay for a CTSV pan. Picked up a new one including windage tray and dipstick for $100 + the ride.

Not fitted the engine yet but looks like it will give plenty of clearance over the stock truck one.

P.:D

Thanks for all the help everyone. The muscle car pan kit at jegs for 149.00 with all I need sure beats 350 for the Holley 302-2. The Holley looks nicer and holds 3/4 of a qt. more oil but when you're on a budget........
Thanks again.

Re: Which oil pan?
 

The GM muscle car pan is a great deal when you need to replace a truck pan. Unfortunately, it's not much help for gaining clearance over the truck pan. The H3/muscle car pan is just over 1/2 shallower than a truck pan (7.75" vs 8.34"). For comparison, a CTS-V pan is 7" deep, and F-Body pan is 5.62" and the Holley 302-1 is 5.71".

Here's a link to various oil pan dimensions:

Re: Which oil pan?
 

Yup Dayj1 is right. Don't know how I missed the actual numbers on the jegs page too. Thanks for the correction Dayj1. For some reason I thought that pan was closer to the fbody pan.

Re: Which oil pan?
 

I installed the "F" body pan and made my own motor mount brackets using the organ donor 2001 ls mounts. I chose the "F" body pan for the additional reason it's the thinnest up front below the timing cover. My steering linkage center section ( stock linkage) almost rubs the pan as it passes under the front lip. The clearance is 1/4" max. The low sump area is still higher than the factory cross member by maybe 1/2".

Re: Which oil pan?
 

Jimmy,

I just did this and I used a stock truck oil pan. I can take picture tonight and post them but the truck pan is just fine and fits like a glove. Personally I don't see any reason to go with the lower profile pan. Have you already installed your engine and realized that you want a lower profile pan? If not, and if you are on a budget, I'll say go with stock and spend the money elsewhere. Believe me, there will be more i$$ue$ that will come along with this swap.

Re: Which oil pan?
 

With most mounts the truck pan is going to be lower than the crossmember. Usually in the range of about 3/4" lower. That is not a problem at all for stock height trucks. But, if you lower the truck enough, it becomes a real possibility that you'll catch the oil pan on something. It's much better to drag to crossmember than the oil sump. I don't know the OP's reasoning behind wanting a shallower oil pan, but this is one possibiilty.

Re: Which oil pan?
 

This is true. I just talked to a guy a week ago Sunday that broke his oil pan because it hung lower than his cross member. He said that it was not a fun experience...... Also had a guy looking at my '67 Panel when I was putting gas in it and while talking to him he mentioned that he had his truck oil pan sectioned and welded back together to shorten it. Not sure how that would work but he said he hadn't had any trouble with it. I would think you would have to get a shorter pickup tube for the oil pump. Dunno what they look like inside the pan.

Re: Which oil pan?
 

Oh ok, I now see the reasoning behind the question as a lot of people likes to lower these truck. Mine sits between 1-2 higher since I have HD suspension so probably that is why it was a noticeable issue to me. I'll check when I get home tonight how mine sits and I'll also post some pictures.

Re: Which oil pan?
 

Its pretty straightforward, just a matter of getting all the oil off the weld surface, sectioning it like you would a body panel or anything else, and weld her up. The oil pan is technically a support structure on the engine, so it is important to get a good weld and only use like-material.

As for the pickup tube, its possible to modify one, but its crucial that the pickup tube rests at the lowest/sump point. As long as it doesn't have any kinks or an excessive length, it'll work just fine.

Re: Which oil pan?
 

Thanks everyone for all the help and conversation. It really helps listening to all the suggestions. My 68 has been dropped 2-1/2 inches. The oil pan hangs about 2-1/2 inches below the cross member and about 2-1/2 to 3 inches from the road. I think the Holley pan may be the best choice for me.

Re: Which oil pan?
 

Thanks for the input on that. I guess if a guy shortened the tube the same amount as the section he would be good to go. I am going to be picking up a '01 truck 5.3 and all matching components in the next couple of days so that's probably what I will do....

Re: Which oil pan?
 

It's funny that I never paid attention to the oil pan when I installed the engine. Mine sticks about 2" also and I am not comfortable with that, even though my truck has a lot of ground clearance. I hope to build a skid plate soon that will provide protection to the pan, last thing I want is a hole in that thing.

Re: Which oil pan?
 

Cadillac CTSV pan...

Re: Which oil pan?
 

Does anybody know what dipstick and tube is used with the Holley pan? My dipstick is the wrong one for the motor.
Thanks.

Re: Which oil pan?
 

i second this.

Re: Which oil pan?
 

I'm running an Fbody pan with a modified truck windage tray. My truck is fairly low, however the shallow fbody piece gives plenty of ground clearance and is well above the crossmember.

Re: Which oil pan?
 

Does anybody have comparison measurements or pictures to compare the F body and CTSV pans? If the CTSV pan is about the same as the Holley pan I may go with it instead.

Re: Which oil pan?
 

You guys can keep your factory pans I'm using the Moroso Pan: http://www.summitracing.com/parts/mor-20142 because it offers 7 quarts and the usual standard baffles and trap doors. I'm future proofed to build a big inch engine too.

Re: Which oil pan?
 

Which motor mounts/engine stands are you using?

Re: Which oil pan?
 

Won't the fbody create a possible clearing issue as it will be closer to the crossmember? I am at work right now but IIRC my oil pan is very close to the crossmember and my LS engine sits in the same place as the SBC. You can gain clearance if the engine sits a few inches back though.

Re: Which oil pan?
 

If you use the ECE LS swap mounts, the Fbody pan won't work because of the crossmember interference. That was the reason I switched to the CTSV oil pan. If you are using some slider mounts such that you can move the engine back, then the Fbody pan will probably work.

Re: Which oil pan?
 

Boosted C10 Thanks for the pictures! That really helps! Hart_Rod I'm using transdap 4575 mount adapters and the stock C10 perches and mounts. It fits in there really good. The CTSV pan looks like it may be the one to go with but I need a part number. I don't want to be poking around the wrecking yards looking for this pan and trying to remove a good used one so I'll probably buy a new one at the dealer or from the aftermarket guys.

Re: Which oil pan?
 

I would recommend the Holley pan. It may be more money, but I love it. Just be sure of which one you need. I ended up installing the 302-1 at first and then found out I had an interference issue with my cross member and had to go to the 302-2. Fortunately, I was able to return the 302-1 to Summit. You need to understand though that my chassis is a custom chassis with rack and pinion. The 302-1 hit my rack and pinion and there was no way to know that ahead of time.

Don't be scared by the windage tray modifications either. They are no big deal. The 302-2 pan requires more windage tray modification, which I didn't want to do, so I bought the right windage tray (PN 12558253) from Summit for $24. The 302-1 windage tray mod is easy. If you go to Holley's web site they even tell you what windage tray you need and what oil dipstick to use. Lots of info at their web page.

Here is the comparison between the 302-1 & 302-1 pan. Also a picture of my LS3 with the 302-1 installed first.

Re: Which oil pan?
 

Here are pictures of the Holley pan install with windage trays. The first picture is of the windage tray for the 302-1. Second one is with the 302-2 windage tray.

The windage tray for the 302-2 needs to be cut, while the 302-1 has a minor mod around the pick up tube bolt. That's why I just bought the proper windage tray for the 302-2.

Re: Which oil pan?
 

You can see I had a clearance issue with my rack and pinion with the 302-1 by the first picture. I had to go with the 302-2 (2nd & 3rd pics) in order to get the proper clearance for my rack.

Re: Which oil pan?
 

Here's a couple pictures of my chassis and LS3 with the 302-1 installed. You can see I had a lot of clearance until I installed the rack and pinion. Again, I would buy the Holley pan. You will not be disappointed.

Re: Which oil pan?
 

I think I'm going with the Holley 302-1. I was thinking the 301-2 would be better for me because of the very shallow front end but I'm concerned about the 9.84 inch fore and aft length of the sump may hit my cross member. I think the 302-1 front depth of 2.42" and sump measurement of 7.65" should work in my truck.

Thanks everyone for the help! It really makes a difference!

I use the ls2-ls3 factory road race pan in my lsv8 911. it is the shortest of all ls oem pans and is a gm oem pan with baffles for hard cornering. gmpp 12624617 it is only 4.25" tall.
