Im starting a job at autozone next weak.
I get a 35% discount – durning July I get 50%.Iv been looking around and I can get – crank -PRO_SERIES oil pump (50% more psi) – main bearings – rod bearing – for 138$.
Soo I would like some advise on how to replace them….
Heres what i know.
Trans. Place trans jack under truck – remove bell housing and torque convertor/fly wheel bolts – remove trans coolent lines- drop drive line from rear end – unplug shift solenoid block on top of trans on passenger side – unplug shift linkage – remove all other wires.

Ok thanks guys!!! Well let me ask this.
Do yall think it would be a good idea to pick up a good running 302 for less then 500. Then take it to a shop and have it rebuilt???
Im sure yall seen my post about the bad rocker arm!!! I ended up pulling both heads and fixxing them my self. I had a friend who builds race cars mic the clyender walls he said they wear well within spec the best he could tell with out pulling the engine apart.
I installed a after market oil gage and it shows. 60psi at cold start and then 20 psi @ idl then 40 psi driving…..
What do yall feel is a good oil psi for this engine???
I got the truck back together and its running great just as good as before….
Thanks all.
Honestly, if you can get a good running motor for under 500 bucks, why rebuild it? How many miles are on it? I would just swap it in, and then look at rebuilding your old one as time/funds allow, and then you have a backup/parts motor. Just a thought.
Oh, and as for oil pressure, a rule of thumb I was given at school was at least 10psi per 1000 rpms. I’m curious what everyone else thinks about that figure though.
I agree with Beefy on the engine idea. I would purchase a low mileage salvage unit and rebuild your old motor as time allows.
+1 for Beefy’s advice.
If you’re going to buy another engine and invest in a rebuild, start with another V8. The 351 Windsor is the Ford with the improved bottom end. The 302 began as another dumb Ford idea 50 years ago. The main bearingOk that makes really good since… I do have to disagree tho with yard dog and the 302/5.0 being junk. Iv had a few of these engines/trucks and iv drove them threw hell and back and have yet to see one – Kock – snap a rod – spin a bearing… and let me tell you im no easy driver on my trucks.
I dont do alote of towing or 4X4ing but I do drive it.
I had a 1990 ford f150 with 498k on it. and i put 200k on it my self and never once did any real work with it…. I drove it from okc to Nashville Tn dong 110mph the whole way!!!
I will say one thing i have noticed about these engine are rear main leaks.
Dreamer i would like to know more about the e7 block brother!!!
Everything ealse yall said makes perfect since….
How hard would it be to put a 351 in the truck???? Would there be alote of modding or converting???
I don’t believe the the 302 Ford is “junk”. It does have weak main bearings, as we would expect in an old 221 cubic inch engine intended to run 150 hp. That’s not much stress on those little mains. When Ford bumped the displacement up they finally beefed up the mains in the 351 Winsor.
It’s not just me who prefers the stronger mains in the 351, it’s Ford.
Those engines are all very light and compact. I think they’re a good choice for some applications like Trans Am racing, but then they need a main cap girdle to add strength.http://www.carcraft.com/techarticles/11 … index.html
That will be a good read for you.
If you decide to drop in a 351, you need to figure out if you wanted to use EFI or carb.
This engine gets bigger by the post it seems. Something to consider is that I’m pretty sure with what’s happening in the Middle East right now gas prices are going to do nothing but go up, that said you might consider this when figuring out what displacement you go with because the bigger the engine the thirstier it gets and it would be a shame to have a really great engine that you can’t afford to drive. The Europeans figured this out some time ago and went to smaller displacement engines with forced induction in some cases, same or greater power, less displacement and weight.
Eric you just love breaking my heart dont you.!!! lol.
Next to my son my truck is the only joy i have!!! I dont care how much gas it drinks. I want the best i can get for what i got…. In the last 3 years i havent so much as got my self a new pair of shoes… Infact my glasses i have on -well theres missing the whole right side ear peace…. Lol
Im not one to care much…Just as long as my sons taken care of and after him my truck.
anyway. dreamer thanks for the site. Eric thanks for the smart advise verry strong and good point.
Yarddog i do see what your saying and thanks.guys idk what to do.
I found alote of 351 blocks on craigslist for around 150$…Most of them had some kinda bore work or such done to them.
I coulden find much as far as a 302 block goes.A -Im thinking that buying a 302 with low miles for less then 500 and swaping ]- rebuild mine in the mean time.
Or should I.
B – buy a low miled 302 or 351. and go threw it and rebuild it peace by peace and in the mean time drive mine until it wont go anymore????
If i do B i would probably push more for a 351 efi.POLE!!! vote A or B and The favored on I will do!!!
Agreed with dreamer -that is what the smart money says. I do plain to go EFI….
I dont pain to do this over night or within a weak……
I plain to buildd it as i go.
This way i have time to get my parts and engine hoist and all that???What is a roller motor??? I had a friend of mine who has been racing sprint cars for over 30years come by and we got to talking about the truck.
He wanted to take a look.
He said it had a damn good engine in it… He said it was a roller motor?
He said the oil psi is normal and does believe the engine has the miles the truck says.
He did advise i put 20/50 oil in the engine with some lucas.Soo what is a rollor motor???
I just changed the oil… I used Rayol purple 20/50. Rayol purple filter.
The oil pressure hot now is – 45/50 idl and 70/75 at 3000rpms.Maybe she just wanted a oil change….. Come to think of it. I may have put synthetic oil in it a time or two….I know i put motorcraft part synthetic the other day bc It was the cheapest. Maybe that was the problem.
A roller motor just means it has roller lifters instead of a flat tappets. Basically there’s a wheel that rides along the came instead of just a flat metal surface.
But anyway, 20/50? WTF? Now you are looking at starving the top of the engine at cold starts, especially when it’s cold out, and hurting yer gas mileage. If you need to use that heavy of an oil to keep oil pressure up, you’ve got some problems bud.
You said the truck is a factory 5.0. If you have the means to find a low mileage 302 long block, just swap it in. Then you don’t have to worry about new PCM’s/wiring etc. Quick and dirty. Then MAINTAIN the engine. Don’t skip oil changes. My ’91 has 150k miles on it’s 302, and it only does work (towing, hauling etc, it’s not a daily driver) and runs good, so I know they will last, as yours already has.
