This was an excellent thread but IIRC the OP finished the swap didn't have any oil pressure but rather than replacing the oil pump (easy BTW) he scrapped the project. Just wonder if he ever got the 4.9L working.

???

If you are referring to me - the swap was completed and drove daily for several years, this car then became a project once again when I swapped in the f-body interior after seeing JScott's thread - and then I drove it daily some more. I then changed jobs and had too many cars in the garage, so this one was cut (sold to a young kid in Saskatchewan). Sometimes I miss it.

Also, never had an issue with the oil pump - the only issues I had with the car was destroying a SPEC clutch (back when they used cheap metal on the pressure plate and the springs broke out) and and early overheating issue (which was attributed to an air bubble in the system). Edit: actually I killed a Centerforce clutch early - piece of crap would not hold when the beans would be put to it - SPEC at least sent me the new modified pressure plate, Centerforce basically said too bad...

This car had gone through a lot of transformations: originally a 86 4 cyl coupe, then a 4.9l "SE", then custom tail lights (design based on the 91 GTA), then a "GT", then the f-body interior. lol

Oops, sorry about that. I was referring to Josef644 build that lost oil pressure. He did a neat 4.9L swap but lost oil pressure, then gave up and put in a 3.4L P/R engine.

I'm still driving my 88 4.9. Puts a smile on my face every time I turn the key! A bit worse for wear cuz I drive it year round. On my second isuzu 5spd; (stripped second gear), but kept the centre force clutch. So far so good!

I don't have a specific thread, but I took all the information from this thread. There were some challenges mating the tach with the 4.9l, but got it all sorted along with some other novel solutions to some problems (HVAC controls). My pictures in this thread are also probably dead, but they are too spread out over many pages for me to really go back and update the links. I probably have some pictures laying around of the finished product if you are really interested. lol

I never resolved my code. Runs pig rich so I stuck E85 in it and it seems to not run rich but has cold-start issues. Blew a Getrag transmission mount. Waiting for a replacement. Can't seem to kill it...
