ughhh some people...

the silly things i argue with people about


my friend has a '77 maverick siting on flats for years on the side of his house with the original 302 in it but siezed up. anyway he's telling how he was going to buy a '77 maverick 302 engine off ebay for $1000 down in NC but the guy was trying to screw him or something so he didnt get it. so i said that we can probably roll down the junk yard tomorrow and get a running 5.0 for a few hundred. he tells me he doesnt want to convert it from fuel injection. i explain to him that thats not really a big deal since his current 302 can provide us with all or atleast most of the conversion pieces. he then goes on to tell me he doesnt want a 5.0 cause theyre crap and actually less cubes then a 302. according to him "a 5.0 is actually a 289 or something less then a 302". thats when i just gave up lol. the only reason i suggested a EFI 5.0 is because i know there wonldnt be any carb'd running sbf's in our local yards since there so old, on top of that i figure a roller motor might be a little better anyway.


ive already tried to buy the car off him but he's not budging so i figure i could atleast get him in the right direction to get it backon the road. its a '77 2 door with small bumpers, grabber hood and spoiler, buckets, floorshift c4, v8 p/s, p/b, in black primer. he paid $2300 for it and blew the engine in 2 weeks a few years ago. been sitting on the side of his house since

 

Blew the engine 2 weeks after getting it and thinks that a 5.0 isn't a 302 ...

If he is that dim-witted, give it a couple more years and you'll own that car cheap.

 

a 5.0 is a 302 a 289 is a 4.6L

 

5.0L is actually really a 4.94L (301.9 cid)

289 is a 4.72L (288.5 cid)

4.6L is a 281 Mod motor.



I've heard that the 5.0L blocks ARE weaker. They say the block will split in half much over 550 HP (Mustang guys). But for a daily driver...


I'm with CaptainComet, sounds like he'll give up and sell it eventually.

 

Yep. I think about any stock block 302 is a ticking time bomb past 500 horse, 5.0 or not.

 

I've seen mexican blocks (302m ) and the main webs are a lot thicker than a regular 5.0 . BTW, Mexican 302's stopped being produced until 1984.

 

JUst tell him to put a 460 in it.

 

NAW....... He just needs to put a 427SOHC motor in, complete with the Tri-Power intake with three Holly 2300's and a Paxton supercharger........ Although with that set-up.... he'd probably be too scared to even take it out of the driveway....lmao

 

Better make it three Paxtons, being that it is a tri-power and all...



Assuming the car doesn't flip over when you turn the key, sounds like a plan .

 

Graflexmaster...I think you have room in your garage for at least one more car....

Love the avatar...I missed the one aurora that occurred when I live in Kent, WA due to overcast skies. Still need to see them before I leave this place.

 

I have A blow 289 and my question is. will the parts off of a 5.0 motor fit onto a 289? if so please help on the conversion.

 

the crank and rods are diffrent between a 289 and 302

 

What an idiot lol. 5.0 isn't a 302.

 

what i ment was .will the intake and heads off of the 289 work on the 5.0 ?

 

Physically, the 289 heads and intake ought to go right on a 5.0 block. You want to be sure to use intake manifold gaskets for the earlier heads because the water passages are shaped different. I believe the chamber size on the 289 heads will be smaller and you will need to check your combo so that you aren't running the compression up higher than you want to. Sorry I don't have more specifics there. You might want to start another thread in the Tech section. Somebody here will know more.

If your 5.0 is a roller cam motor, you also will want to run a distributor gear made for that. A roller cam will wear an old style distributor gear out in no time.

You will also want to group the accessory drive. You don't want to mix and match, because some later water pumps are reverse rotation. If you stick with the early stuff, you ought to be OK, and your heads have holes in the right places, etc.

Balance on the later 302s is 50 oz, not 28 like the 289, so you need a flexplate or flywheel balanced for that. The harmonic balancer used should be the 5.0 unit also. Don't know if an earlier crank pulley bolts to that.

Firing order is different on 5.0 (I think) and you will need to change to that.
