Since I will be having this oil pan off, and KED said it would be worthy of installing a new oil pump. While in my search for the cost of these, I found that they have a high volume pump, cost about 20-30 bux more. Would you say its worth it. Has anyone installed one?? Can I get some Pros and Cons??

I'm new to the INSIDE of the engine and not sure as to why I would really need one, or not need one. But any part that is getting replaced is getting the HD or performance part, etc.

 

in all my 400 poncho dealings, I've always hear that when upgrading the oil pump, go w/the high volume, not high pressure. I believe it is a good choice for your motor.

 

I belive it said "high volume", I will look again.

 

KINDA WRONG...
With the high milage of a motor it pays to replace the easy items as they are in your hands &....
An oil pump falls into that catageory.
YET for our f body cars,
I have yet to change a pump for my swapped in 3.4 engines. Remember I got my 3.4 mills with lower milage.
High volumn is the answer or get the one for a S-10 Blazer.
Even when my 2.8 Blazer engine was going I was still able to register close to 60-80 LBS pressure.
I was pretty impressed.
With one of my swaps, tho, I did tack weld in the pick up screen, as I adjusted screen lower.

 

Right ked, my 130+k 2.8l engine still registers about 60-70. But since I might replace, I'm thinking about doing the bigger "better" one. This is also if I can afford the cash. This engine has 71k on it. So do you guys think I will be fine for a few years with the stock pump?

Rem, I am attemping some of this on a budget

 

Id ask around some more but ive heard many time that them bigger pumps are for suckers, it will hurt you in the long run. unless you run a bigger pan/more oil you can pump your pan dry and spin bearings beacuse it pump it up top so fast it cant get back down fast enough.

 

Cheat & Cheap!
Separate both pumps & measure clearances at housing & gears.
Use the tightest specs.
AND
Go to dealer, obtain a new stock pressure spring & gasket (yep a gasket!).

When installing, make sure the pump screen is about 1/2" from bottom of pan, remove pump w/screen set just right, tack weld for a heartbeat (just a good solid quick spot!).
DONE!
You've rebuilt oil pump.
NEXT!
IN THIS INSTANCE
V-6 oil pressures are higher than V-8!
Our gauges read to 80 lbs.
V-8, 60 pounds!

Pretty much keep it stock & it's just right. Your current example proves this point!

Incidentially, that current 2.8 block is good for a quick 2.8 swap for someone.
Sell that engine before you remove it.
Get paid to remove the 2.8!
I once sold a bad running 350 with rod knock for $200 because I drove the guy around in my car with the engine he was gonna buy.
Made my effort to remove engine better feeling!
Start making money right away!
Atleast for the gasket funds!
You have purchased the complete engine gasket kit by now, right?
And again, purchase a new rear main seal, too.
Cheap insurance for a lousy spot to get to again.

 

I'm prob gonna keep the 2.8l, but as soon as the 3.4l is here, the flywheel, starter, oil pan, manifolds is all up forsale.

Will keep stock pump, that saves me cash too.

This swap will be slow, so I'm in no hurry to buy gaskets and such.

Plus, I don't get payed tell friday. No cash right now

 

Keep your spare starter!
You keep the 3.4 flywheel & Balancer.
2.8 stuff can go, tho.
I've got three 2.8-3.1 flexplates now!
I'd keep the spare manifolds, too.
The V-6 manifolds crack easy!
Don't remove the 3.4 manifolds, they mate up to the exhaust system, perfectly!

You have my original 2.8-3.4 long block swap boogie thread, right?
Most if not all tips in that thread.
And when the 3.4 arrives at your door step.
Money
MUHHAHHAHAHAHAHAHA
FEED ME MORE!!!!
I NEED TO TO RUN!!!!!!
I AM CUSTOM ENGINE SWAP!!!!!!
Enjoy your packages!!!
I had a blast opening up boxes of vintage 1947-1950's Lionel trains I bought from guy in New Jersey!
I'm awaiting the insruction manuals to arrive anyday now from an ebay purchase!

 

Engine is coming from an automatic car, I have manual. That flywheel plate wont work.

I also have headers, No need for stock manifolds. If you want them ked I will swap oil pan for manifolds. Hopefully I wont have to cut the EGR tubeing off to make work on my headers.

Starter are diff. I fig I'm using old flywheel, better of using old starter. Plus, dunno what the difference is

 

You're gonna have to find out how to make that flywheel correct for a 3.4!
Different BALANCE than a 2.8/3.1!!
Same size but give me a shout about the starter.
I have plenty of 3.4 manifolds & 2.8, too!.
Remove thoughtfully & put aside in nice condition for future usage.

 

get flywheel from 93-95 manual f-body. problem solved I think starters are same, I never had to change mine. & old 2.8 AC Delco starter tests just fine.

 

Damnit, I gotta find a new fly wheel?? ^&@$@&

Ok, manifolds will be gone.

Starter looks totally diff, not sure which I will use. If I have to go with 3.4 flywheel, I will prob stay with 3.4 starter


Engine looks good, will have pics up this weekend.

Karl, please check on that oil pan for me

project 85, did the power steering hoses screw in to box just fine??? please tell me how you did that.

 

You need the old style pan?
What about timing cover?
I'll keep ya posted

 

Still unsure on timing cover, I want to get a pan and see whats so different before I get that part. Shouldn't be to hard to find.


Yes, need the old style/s10 pan.

 

I dont think you would ever run the pan dry with any pump. I highly recommend a high volume pump. The factory is only going to give you what is sufficient.
The more volume/ and pressure of oil that separates the metal from the bearings the better. I wont rebuild an engine without installing a high volume pump.
I raced 9 years and only lost 1 engine due to crank failure.
