Re: having issues
ok.. just got to the shop.. first thing i did was check resistance on the wires.. heres what i got
1-733, 35" length
2-657, 33"
3-543, 27"
4-576, 29"
5-544, 27"
6-532, 25"
coil- 251, 13"
they all are around 19-21ohm per inch

Re: having issues
map is plugged in and egr plug is on passenger side aint it? this is driverside in the picture
egr had been eliminated already when i got the truck.. so it might be i duno.. but its only about 3"s long comin out of the stock harness loom.. im uploading a vid in a second.. i tried the plug wire thing.. pullin one off at a time, couldnt really tell the difference.. there might have been a slight change in cylinder 5 couldnt really tell because of how crappy its idling

Re: having issues
Is the engine at TDC with the mark on the balancer also at TDC when you put the distributor in? You've probably checked this.
There are two marks on the balancer. As you look at it from the front, with the correct one at the 12 o'clocl posn, there is another one at 2 o clock. I painted the correct one with white out to distinguish between the two easily.
Have you done a compression check on all the cylinders? Mine wouldn't start and I had messed up my rocker adjustment. Rechecked them and it fired up great.

Re: having issues
yea everything lined up.. the only thing i can think of is the rocker adjustment.. i was gona do that first thing today.. but wanted to try some other things first.. but thats what im goin to go over again.. machine shop assembled the short block since i ended up having a bur on the oil journel on the new crank.. tore up a bearing just from assembly.. so i let then just put it together after they fixed it, but no i havent checked compression.. i guess i just trusted it to be good since its all new and the machine shop did the work

Re: having issues
Do that and try again - hope to read about a successful running engine. What lifters have you got in there btw?
Are you happy doing the rocker adjustment? 850s needs a 1/8-1/4 turn and the 875s are 0-1/8 lash.
Just offering - if you need any tips, click on the project thread in my sig and it links to two methods. I like the one where you only turn the engine over once to do all valves.
Good luck - should take you an hour

I have no idea wst exactly they are .. I know the cam.. Rockers and lifters are comp cam, push rods are diamond racing.. But dont know the specs as they came already in the motor with the truck..

Re: having issues
Reason I ask is you need to know the specs otherwise your rocker adjustment will be off and you could collapse the lifters.
875s are also louder so I wanted to know how they sounded to you. I hate mine and will replace them with 850s.
Did the builder not get you a build sheet with parts etc?
You need to find out if you're adjusting the lash dude.

Re: having issues
I guess a compression check will verify if you need to make any rocker adjustments - perhaps do that first. You should get around 150-160 psi on each cylinder if it's new.

Re: having issues
I never knew that. I like that check, I will tuck that into my memory for the future.

Indont have a clue who built the motor last.. I just used what came with the truck.. Only thing new is piston and rings.. Crank and bearings and headgaskets etc. How can i or how ambi spose to figure out what they are .. Beleive me i been lookin online from other forums about the truck to try n find what the specs are but allni find is that they are comp cam..
Tye post above u.. I will try that with the balancer i have done all the tdc stuff and yes its with the correct mark.. Second one on rotation.. I did buy a new balancer but havent got to that yet.. Another thing i had wondered aboit is if the cam is out of time.. Whenni got it back from the machine shop i checked over all of it before i put the rest of the motor back together.. And the timing marks were alined on the gears with the chain on.. So i figured that was all good.. I jus hope it aint that.. If it was wrong wouldnt valves be hitting pistons etc? Id hear that i would think.. If it aint rigt ima b one pissed off mofo.. N the machine shop is gona hate ever seein me again if i go up there

Re: having issues
Stock trucks had 850 lifters and it is highly likely they still are 850s. The only way you could possibly tell would be with a probe - the clips on the 850s are different to the 875s. You would need to remove the lower intake (BIG PAIN IN THE ASS) or get a fibre optic camera/cable and insert it down the hole where a push rod goes. 850s look like a paper clip holds it together whereas the 875s are a bit more secure - can't remember what it looks like but I think I may have a pic.
If your valves were hitting pistons, yes, you'd hear it. I think it's either an ignition problem at this stage but you're rapidly ruling those out, or a simple compression problem.
Do a compression test and post up the results of the cylinders. Like I said, 150-160 psi is what you should be seeing.
Hold off on screaming at the machine shop - I called up my guy and thought he put the rings on wrong and it was my dumbass not doing the rocker arms correctly.
You'll get it going :tup:

Re: having issues
875 lifters
I did not realise that the designs were different - it would appear that GM makes the 875s and 850s. If you can see a paperclip like the left hand one then you have GM and that is better it would appear.
