awesome car man. glad to know someone in Fresno has good taste lol. cant wait til mine looks just as flawless. props man!

I havnt looked into the actual tests yet, i dont wanna overload myself early one thinking about passing certain tests and having to study one certain area and neglecting others. As of right now in class, my engine instructor will give us the "go ahead" and register for this cohort program through the school which pays for each ASE test i take for the first time. I basically want to become a master mechanic. I just make sure to study and read before lectures, get as much hands on experience outside the classroom, wether it be testing my own vehicle for electrical problems i learned how to diagnose, or how to properly clean engine components and measure using micrometers, end play gauges, ect. I dont wanna lag on this program

The bolt was too long and broke off a piece of the block casting, wedged in the timing chain, jumped timing causinh all the valves to smack pistons. Head was thrashed. sorry i was tired when i wrote the story i seemed to have left that one out

Ok first off, sorry my profile ans signature are misleading and i left out lots of information (I will shortly change that). Second im only 20 years old enrolled full time in an Automotive Technicians program so most of my time is spent studying for my ASE's so most of my time and attention is devoted there. Here's the story, i found the 74.5 260z at my grandmas house last year and me having mo car decided to restore it and use it as my daily driven vehicle. The motor was orginal, P30/E88, garbage smog control carbs n36 manifolds. My father being stubborn would not let me junk them for original S.U., triple mikuni, or webers. I spent weeks fighting those dreaded flat tops. The best i could get was an idle at 900 and a drive that was less than pleasant. After much debate he gave in and decided that it was not the most effective fuel delivery system. He opted for the clifford/holley kit. Yes i know that money couldve been spent on triple mikuni or nice rebuilt pair of S.U.s but being the muscle head he is i settled for that, i wont argue with someone whos willing to spend that kind of money for me. So that was that and the car was now operable, but not legally. While i waited to save money for registration and several months of insurance, i stripped the car inside and out, sanded her down and primered , cleaned up the wiring, bought recaro specialists, and MSA victory spoiler and front air dam with cooling ducts. Heres where it gets interesting; I decided to overhaul all my gaskets, so i pulled the motor (p30) disassembled it and replaced what was given to me in the gasket overhaul set including valve stem seals. Heres where i foolishly did not think AT ALL. I replaced one of the smaller water pump bolts with a new one from a assorted set of fasteners i ordered from eBay from a private seller. Upon doing this i broke of a piece of the block casting, creating a time bomb. I had no knowledge of this and when i was ready to turn on the car, i turned the ignition and was only greeted with spinning of the starter. I could tell that no compression was being created so i did a compression test and lost all compression in all cylinders. This is where i pulled this motor and started looking for another one Part 2 Down the street was a 79 280zx sitting because it could not pass smog one year due to a fault in the smog system. When i popped the hood i.could clearly see wiring performed by someone who.clearly did not have any.experience just some.extra wire and electrical tape. This is the motor i pulled, junked the fuel delivery, well i still plan on using the EFI manifold for turbo, but cleaned this motor up, used ORIGINAL fasteners, new gaskets and blah blah. I pulled the 5 speed from the ZX as well.So now this is where i stand. A 74.5 260z with a 79 N42 block with n47 head. Sorry for the novel but hopefully this cleared it all up. Thank you for the info, it really has cleared up my question, next time i will be sure to post adequate information

I guess like car fax? Haha

I may have been mislead*

Not being rude, but it is to my knowledge that this is the motor from the factory. I have been mislead. The tranny also had some kind of code that was etched into it. Is there a service online that i can find. This motors history?

I was pressure washing my motor today before dropping it in, and after finishing this intake/exhaust side of the engine, i noticed these big white markings. At first i thought it was something of unknown substance that had melted onto the block years ago, but as i cleaned it up more and more i seen it was a set of numbers and letters. I have not seen anything like this before..(I'm only 20 so i have not really seen anything) it looks like maybe some kind of service number? i know this motor was never picked up from the junkyard as the PO bought the car brand new, didn't pass smog one year, and parked the car. im thinking that it might be rebuilt? im not sure any one else got any idea that can enlighten me?
