    Well, we found the problem with mudnutts oil pressure. Remember the problem was it had lots when he fired it up but after it warmed up there wasn't squat.... The main bearings were the wrong ones!!!!!!!!!!!!!!!! They were marked right as .010 over on the box but the bearings were wrong, they were standard. When we put them in we got into too much of a hurry because we both had to work that evening and did not plasti-gauge the bearings, bad move......
    After we checked everything else that could be the problem we decided to pull the engine. We pulled the main caps and put the piece of plasti-gauge on it, re-applied the main cap, torqued it and removed it again. When we pulled the cap back off the plasti-gauge just rolled of the journal and fell into the engine. We just laughed, it was all we could do... Being the good, kind hearted, generous and loyal friend that I am I loaned him a set of Clevelite .010 bearings I happpen to have and they gauged out perfect. We also went ahead and installed a Pete Jackson Gear Drive just for giggles.
    I hope this oversite on our part will be a lesson to everyone, don't get complacent when you put an engine together, measure and gauge everything.
    The engine is going back in this morning. We will let you know how it goes. There are a couple of pics of it on the link below.
    Talk to you later.......

    Everybody has to screw up at least once. [​IMG] I installed the freakin' intake gaskets backwards on one engine. Just wasn't paying attention. I had even noted that they were marked "front" and "rear", then put 'em in wrong anyway later on. Had to remove the entire TPI system and intake to install new gaskets the right way. [​IMG] The engine ran way cooler without the front coolant ports blocked! [​IMG]

    Yeah we all gotta make a few mess ups [​IMG]. Actually this is a good story when someone is watching me do a motor and goes why you do that? why you do that... so you tell them... and they awww... that will never happen. Building an engine is kinda like cutting a board... measure twice, cut (or in this case assemble) once. Glad you found the problem...

    I did that once and got lucky ... very bad move! I didd end up with a nocking sound after some time ... ended up being piston slap? At a connecting rod?

    Just knocked a bit at start up for 120,000 miles 350/350

    IT RUNS!!!!! IT RUNS!!! We got it back together and it is running like mad. That thing has some serious power with those Vortec Heads. It sounds good and has all the oil pressure in the world. I will post a couple of pictures in a few minutes of today's labor.

    first off i would like to thank chevyracing for all his help with this engine build. if he had not stood around watching me work and giving me bad technical advice i never could have screwed it up in the first place. thanks john[​IMG]. seriously, thanks could not have done it without ya. well maybe without you but not without your garage, tools, air, airtools, electicity, partswasher, gasket sets, all those nuts and bolts, zip ties(and i know how attatched you were to those things),<font color=blue>lol!!!!!!!!

    BowtieBlazer,
    The wheels are made by Centerline, but I forgot the Technical name of them. They are 15 X 10. I have had this Blazer since 1981 and I love it too. The body is absolutely pristine and it is a very strong truck.
    The thing I hate about having one like this is now I need to build one I can go tear up. I have had death threats (jokingly) from some collectors if I mess this one up.

    Have a good day..

    Hey Bob...mudnutt...,
    Someone had to operate the camera and open the beer.. (remember, you couldn't figure the camera out....LOL)
    Seriously, no problem, glad it is fixd..That thing is a monster now for sure. It has all the power you will need. Don't worry about helping me pick up the tools and cleaning the garage, I went ahead and stayed til midnight and got it squared away..No problem ..LOL.
    Enjoy your truck bro, I am looking forward to muddin' on the 25th of November, It sounds like a blast.
