stock around 15.3 with the fuel injected engine
It would be either the Engine or the Battery.
Whatever you do don't buy a junkyard diesel engine. The 350 car diesel was built off of a 350 gas engine at the time. So it did not work well and was very unreliable. I would suggest rebuilding your old diesel, or purchasing a new orre manufactured unit from GM. Theses routes will fix the common problems that made these engines hideously unreliable. GM basically killed most diesel engine car production with this unreliable engine. Everyone assumed every diesel was this bad. That is not the case, most other diesel's such as the Chevette 1.8 Isuzu diesel, and the VW diesel's of the time are very good. Hope I didn't sound preachy, I was just trying to help.
most likey dont think they changed it in that time or even changed it at all
go to autozone.com and enter your vehicle info, then click on repair info, and you will find help
the last time i changed the spark pluges in my 86 subaru gl wagon, i took the engine out. seriously, it needed a clutch at the time.
??? Your question makes no sense. Ask this question again and this time in an understandable manner. List the engine size.
Same as you would any other engine, get a chiltons manual and it will explain the process however get some help. The first time you do an engine swap its easy to get in over your head.
Yes - probably a long time ago
The 1986 Chevrolet IROC-Z, equipped with the 5.0L V8 engine, typically had a 0-60 mph time of around 6.5 to 7 seconds, depending on the specific configuration and conditions. This performance was considered impressive for its time, contributing to the IROC-Z's reputation as a high-performance muscle car. The vehicle's lightweight design and powerful engine helped it achieve these acceleration figures.
sounds like you need a new timing set, it probably jumped time
The cast of The Time Machines - 1986 includes: Brock Yates
