Re: 1987 GMC V1500 Sierra Classic LS swap/build
Got it back together.
What was odd was apparently at some point a checkball fell out... No clue where it came from. I didn't drop valve body at this time to check, I just put it back together.
Started up and gave me codes for IAC and now both knock sensors but runs fine. I drove it and seems like the check ball must have been for 1-2 kick down b/c it isn't wanting to drop back down to first but oh well.
It ran well enough I could justify pulling it now!! So next step is to find me a cherry picker and another engine stand and pull it all out!!
I will drop valvebody once it has already been removed from the truck and check for checkballs. I probably will take top end back off as well when I paint and really clean the engine.
Still plan to go look at a lower mile 5.3 just in case.
Time to make or order me some mounts and get the swap started!! I need to find a buy for my 350tbi/700r4 setup with less than 8k miles!
