Picked up an 84 Cutlass mainly because i lost all motivation on my 72 nova rust bucket and this was very solid.

I want something i can take the kids cruising in, teach them how to work on, see what it turns into.

Goal is to be driving sometime in July, so here it goes.

2 sundays ago I went and drug it out of a guys back yard.

Don't know what this bracket is so off it comes.

Cropped its ears for some extra room.

Bolted up a bare block so i can drop it in easier and figure out mounts, oil pan, exhaust, and driveshaft length

Sounds good, just curious why 80e trans instead of 60e? Wouldn't 60e save some room?

I originally planned on pushing a lot of power in the nova so i picked up the bigger trans. I still may turbo this winter or next

First snag, didnt realize the olds v6 frame mounts were dofferent then the chevy small block. Anyone know if mounts from a 72 nova will fit? They appear way different.

The engine side mounts I had did not fit the advance frame pads.
I ran to summit this morning, they sold me the wrong mounts, that got me pretty frustrated.

Now i either drive out there again tomorrow, or wait for them to ship it. My luck i wouldn't get it until Wednesday if they ship.

Cool project. Glad to see you aren't wasting time and money on a 4L60E. They are only useful in a completely stock application with no abuse, in my opinion.
