1. well up north in wisconsin mudding for a little fun in the mud and well it didnt come out of the one mud hole not running. the 4.9l might be dead cause it wont turn over, it tries. took a breaker bar to the crank and it turns so far then stops. turned it so far and tried to start it and it stops and hits the one spot then stops. so going to drain the oil, take plugs out and look inside and see if their is somthing hitting the piston.

2. got out to hook the tow strap up and the water was up to my waist about half my grill. was on the other end front of truck out of the water and it wouldnt start. time for a v8


<!-- / message -->3.what would be a good option for a v8 if i have to replace the motor? im going to see if i can get the motor to start. but for the v8 im thinking the 302 cause the computer would be easier to find for a 5spd. it might be harder to find a 5.8 computer. i know they made them with 5spds. or are the 5.0 computers about the same as the 5.8's? and how about doing a carburated motor? easier to find a computer just have to get the fuel pumps done. their is a guy i work with who has the same color and year truck but has a 347 in it(5.0l built up), he told me to do carburated cause you can get the power out of them, cause its hard to get the fuel injectors to work with the power add ons

4. well got it home, drained the oil which did have water in it, took spark plugs off, had some water in them. tried spinning it and it would stop, couldnt even turn it, took the head off to see the valves and they are good and tried spinning it and it just stops after spining it so far counter clockwise and then clockwise. i will pop the oil pan off to see wheat it could be next, but from what im thining i will just see if i can find a v8 that is either rebuilt, or has low miles, or get one rebuilt myself and just take the 6 banger out, and drop the v8 in in one day

Heh. You're talking about lots of sensors, lots and lots of sensors, new flywheel, new PCM, probably a new ignition module.

And I wouldn't put a 302 in a truck, in a car it may be fine but for the time, price, energy and gas mileage you will probably be happier with a 351 if you decide on a V8.

If you're going to swap to a V8 and change out all that junk, you may as well do the SD to MAF conversion.

 

well got the oil pan off and seen the #5 cylinder connecting rod is bant and twisted so got to pull the motor. im just going to do the rebuild on the 6er cause otherwise i would spend a lot of money on the v8 swap cause you have to change lots of things. and all i need is my block done on my truck cause the head was done in april. so it would be pretty cheap for a build.
and i also give the truck a beating

 

Let me guess, you didn't pull the spark plugs out before you tried to crank it and then force it with the breaker bar did you?

 

You can't compress a liquid, but I guess that's obvious now :-(
Amazing how it only takes a few ounces of water to bend metal...

 

poor 300 thats called Hydrostatic lockup, Water up to the grille means the poor thing pulled water through the air intake and straight into the engine which trashed a rod your lucky it wasn't more than one.

 

kids these days... hehehe... Next time your truck says: "i don't wanna turn over" you better hear it. Good thing it seems like you didn't cause too much damage.

 

well i knew about hydrolocking engines but what happened was i went through the mud hole on saturday and made it to the other side it died on me cause the plugs got wet and then started right back up so then sunday i decided to try it again made it to the other side and tried to start it but i have starter problems and so we trried droping the clutch which didnt work and stuff. the truck was never burried in water just flew though a puddle. when my friend went to pull me out i got out of my truck to hook the strap up and the water i went through was only half way between my knees and waist. im thinking it is mainly cause i have a k&n type filter in their. i usually put a paper one in. so it just let the water right in. i knew when mudding their was always a risk of this happening when i started doing this. before i tried cranking it i got out and checked the oil and didnt see any differences either and also when i flew through the mud hole i had it in 4hi and floored it in 1st gear so im guessing the high rpm already screwed me over when the water got in their.

how big can i bore my cylinders? i got a quote of 900$ to redo the bottom end cause i got the head redone when i had it apart in april..
i can get a 351 for $400 from a friend but not sure what all comes on it for parts. has 25k miles on rebuild. and then just adding the price of converting it might be cheaper to do a v8 swap but from what i read the m5od is bad behind the 351. i will see how bad my block is before i make a decission.


i know for sure next time im taking it carful. i have driven thought puddles that have been as high as this one before but like i said i always had the paper filters in not the aftermarket k&n.

 

When the water is between knee & waist deep (dunno how tall you are), that's plenty high enough to suck water into the intake. Doesn't really matter which air filter you're running, you'll suck water through a paper filter just as quick as a K&N


As far as a V8 swap, I second the "don't waste time with a 302" sentiment. Put a 351W or a 460 in it. No replacement for displacement

 

yep agreed the 302 wants 2500 minimum to start growing a set of *****. on top of that it's neither significantly more powerful than a 300 straight 6(although hungrier) and no where even close to being AS powerful as a 351W. In my opinion they should have only offered the 300Cid Straight 6 and the 351W for 1/2 tons and then offered those two plus the 460Cid Big Block gas engine and 444Cid Power Stroke Turbo Diesels in 3/4 and 1 Ton trucks

 

$900 sounds like a lot for that. If I were you I'd check the junk yards in your area. These engines are pretty bulletproof and if one turned over and had good compression, I wouldn't hesitate to drop one in my truck and run it.

 

i think the guy thinks i am bringing the whole engine in with the head on so it is 900 and it might be a little cheaper for just the block. all i want them to do is the crank, cam, and pistons and crank rods. i would like to build it up a little bit but like i said i can get a 351 for $400, but the thing i read online is that the m50d cant hold up to the abuse of me that i might put on it.

i would like to do the v8 for sure cause i have the engine out and then just get it ready to go in.

 

Its a rare site to see a 300 struck down so early in its life.

Anyways, i think you should stick with the 300, i know a 351 swap is tempting, but i have never been impressed by it. I always think it would be nice to have a v8, but my 300 seems to keep up just fine. And you can make good power with a 300 if you put a little work into it.

In terms of the tranny, if you do any work to the 300 you will trash that tranny. Even just the stock 300 will kill the weak M5OD.

Good Luck
