Project: 5.3 4l65e 4 door blazer

01blzxtreme · 09-05-2009, 11:50 PM

good to see your still working on it bro...
i am still gathering parts to start mine....

**platour22** · 09-06-2009, 12:19 AM

Yeah im slowly getting there. I just went back to work about a month ago, plus i just moved. So funds are a little low, but still gathering small things i need. Nothering really major i need, i don't think. Maybe exhaust and kwik alternator bracket, computer reprogramming. The rest is just pennies comparied to those i guess. Another $1500 it'll be running.

mknight759 · 09-06-2009, 12:44 AM

Idk 1500 will go fast I've watched a pile of money go into that heep I have out back but as long as your moving foward your getting closer and I guess you decieded to keep it

zx9rgreen · 09-06-2009, 12:55 AM

Where did you move to Paul?

Yeah im keeping it as long as i got a place to keep it. Its in the shop at my Dads now, but he's trying to sell the place so if he does, then i'll have to sell or find a new place. I live in an apartment now, so i can't keep it here.

As far as $$$ i hope i don't need much more. $300 for Kwik Alt. bracket. no more than $300 for exhaust steve gave me his mufflers, hoses, belts, bolts and nuts $200, tranny cooler $250, A/C lines $250, fuel lines and fittings $300, tranny lines $150. MAF $100 = $1850. So maybe $2000 to $2500 is closer. Just guessing on some of these.

mknight759 · 09-06-2009, 01:42 AM

maybe it will work out for you to keep it you have put the time and money in I know you would hate to see it go but you have to do what is necessary i don't think i live all that far from you im about 1-1/2 hrs east of phoenix city al

**platour22** · 09-06-2009, 01:50 AM

If it makes ya feel any better the MAF should be less than $100....I bought a new one off ebay for like $55 shipped....Or you can just go to the junkyard and pull one...Is yours supposed to look like this?

mknight759 · 09-06-2009, 10:18 AM

jared at cp sells new ones for 85

**platour22** · 09-06-2009, 01:02 PM

Yeah i was suppose to buy one from Jared but they were on back order or something.

atl is about 3-1/2 hrs north of me and columbus ga is about 1-1/2 north west of me

**platour22** · 09-07-2009, 07:55 PM

Well put the spark plug wires on and it don't look good to me. They sit pretty close if not sitting on the headers. Are they suppose to be like this. Can i see some pics of someone elses. The last wire on the driver side also hits the steering shaft. Also tried to fix were the throttle bracket hits the water pump. Tried grinding it down, but it don't look like its gonna work. Probably just get a throttle body spacer.

Only good news is the last wire on the passenger side has plently of room so no need to relocate coil.

Petro · 09-07-2009, 07:59 PM

The orange rubber boot looks like it's gonna melt off if you leave it there.....

**platour22** · 09-07-2009, 08:02 PM

Yea its getting cut off anyway. I'm also probably gonna space the steering box out so it kicks the shaft away from the headers a little. Maybe it will clear the plug wire also.

Petro · 09-07-2009, 08:10 PM

I dunno about the one hitting the headers...Have you tried the fit without the heat shields?

mknight759 · 09-07-2009, 08:27 PM

mine looks the same on the drivers side but mine has not been run either just as well thou we gonna run it till it quits don't know about the water pump mine looks different

Didn't know you could take the heat shields of the wires. Would it make them sit in further

Paul I'll help whenever you need with the wiring. With the plug wires when I run the stockers like you I put the DEI heat sleeves on and had no problems. I now have the MSD and the boots are bendable to position them away from the tubes.

**platour22** · 09-07-2009, 09:32 PM

Cool man thanks. I'll run it like this if they melt i'll get the MSD ones. You think spacing the steering box over like you did will help it from hitting that last wire.

It will only take about 5 minutes to try....But it couldnt hurt it.

**platour22** · 09-07-2009, 10:15 PM

Yeah i'll get a few washers tomorrow and try it.

or do they just look like that on the pic?? so would this be a 4.8??

**platour22** · 09-08-2009, 01:16 PM

I guess they are flat top pistons. But i don't think that would make it a 4.8.

**platour22** · 09-08-2009, 01:49 PM

01blzxtreme you got me questioning what i have now. My block has 4.8L and 5.3L stamped in the side of it. Guys how do you determine what is what. All the parts i been ordering have been a 5.3 and nothing has not fit yet.

**Kampz69** · 09-08-2009, 03:26 PM

you check the crank? i thought the 5.3's had dished/domed pistons...

zx9rgreen · 09-08-2009, 03:50 PM

do you have the PCM or VIN

**platour22** · 09-08-2009, 03:56 PM

What do check on the crank Kampz

**platour22** · 09-08-2009, 03:56 PM

Yea i think i have the VIN somewhere steve.

**Kampz69** · 09-08-2009, 04:17 PM

not sure, i do think they have specific stampings on them somewhere. you could measure the stroke too i guess, the 4.8's are only 3.27ish and the 5.3's are 3.62. found this on another forum, maybe it will help:

12552215...364.......cast....medium journal...3.62" stroke, Gen. III, 6.0L
12552216...325,350,364.......cast....medium journal...3.62" stroke, Gen. III 5.7L LS1, 5.3L, 6.0L
12553312...293.......cast....medium journal, 3.27" stroke, Gen. III, 4.8L
12553482...293.......cast....medium journal, 3.27" stroke, Gen. III, 4.8L

**Kampz69** · 09-08-2009, 04:17 PM

the VIN would be easiest lol

**platour22** · 09-08-2009, 04:36 PM

Yea im trying to get my dad to go to the shop and get it. ^^^ won't help cause my motor is Gen IV

**platour22** · 09-08-2009, 04:49 PM

Well heres the number 2GCEC13JX71684545 . If i looked it up right i came up with its a 5.3. As far as the pistons i don't know. But if someone wants to look it up with carfax or something if they have axcess then be my guess. Thanks for info guys.

**Kampz69** · 09-09-2009, 11:14 AM

http://www.carfax.com/cfm/check_orde...opUpStatus= 0

says its a 5.3 there...

meant to ask you this earlier, was there a paint mark near either the 4.8 or 5.3 on the block?

**platour22** · 09-09-2009, 01:34 PM

Yea it does you can see it in this picture. didn't realize thats what that was.

mknight759 · 09-09-2009, 01:40 PM

so whats the paint mark for?

Tim99Zr2 · 09-09-2009, 02:06 PM

stating if its a 5.3 or 4.8?

**Kampz69** · 09-09-2009, 02:16 PM

i had read online that they would make a paint mark on the block near whichever motor (4.8/5.3) it was...

edit: isnt the 4.8/5.3 block stamping on the rear of the block?

It's on both front and rear. It's stamped "4.8/5.3"

It does not have only 4.8 or 5.3 so people have difficulty figuring which one it is.

Older 5.3s had dished but I think the newer ones are commingwith flattops. Not sure.

**Kampz69** · 09-09-2009, 03:46 PM

ah, i assumed it was just on the back. it appears that the paint mark is near the 5.3 in the pic, who knows about the flat tops...werent some of the 5.3's designated as "HO" engines? that would explain the flat tops...

badaSS98 · 09-09-2009, 11:27 PM

Depends what the 5.3 was used in. They were used in a bunch of different cars/trucks.

**Kampz69** · 09-10-2009, 01:48 PM

well his is an iron block out of an 07 silverado....i thought the aluminum blocks were the HO engines, but i really dont know

AmericanMuscle · 09-13-2009, 12:13 AM

if the 5.3 had 799 heads they came with flatops, if they had the 706 or 8xx casting they were dished.

**platour22** · 09-13-2009, 09:42 PM

my heads are 243s

01blzxtreme · 09-14-2009, 12:24 AM

try measuring the stroke, like someone stated above, that should give you your answer....
idk i was just wondering sincei opened up an 02 engine had flat tops and i was told it was a 4.8, plus had water in one of the cylinders,so i just got a 6.0..
the only ones ive seen that only have one stamp are 6.0's and 5.3 aluminum blocks...
it would be best if you measure the stroke, thatll clear it out for everybody...
plus 6.0's also have lq4 and lq9, they are suppose to be defined with flat tops or dished...

**platour22** · 09-14-2009, 12:40 AM

The VIN says 5.3. Its a 5.3! I'm not going to pull the motor and tear it apart again just for second guessing myself for a min. I have no doubt its a 5.3.
