69 Cutlass motor swap

HawkX66 · #1 04-19-2017, 07:27 PM

I know it's pretty straight forward, but are there any issues that I should be looking for when swapping a 70 454 into a 69 Cutlass? I'm about to pull a NOM 350 Olds out of a friends 69 and put in a 454.
I'm planning on finding something with an overdrive to replace the TH350 that I'm assuming is in it. Any flavor better than the next for that? 4L60? I'd like something with the most straight forward, non-invasive install. The body is nice. He's a car enthusiast, but knows nothing about mechanics so I want to keep it turn key for him after I'm done. He wants a nice reliable cruiser with plenty of power, but no more than a stockish 454.

I have seen lots of people use A-Body frames as they interchange so mounts should work on the frame.

PS: You may get a rash installing a Chevy in an Olds. :-)

I've seen plenty on the Olds sites. They remind me of the Mopar guys lol. Very territorial... I'm thinking a 700R4 and the 454 should pretty much slide in. Maybe extend a couple wires for alt. that's on a different side possibly. Driveshaft might be an issue too.

I agree.

I was all Chevy till Dr Olds arrived:-)

Dave -- been there ... done that. You'll need to move the trans crossmember back as the 700's mount is further to the rear. The driveshaft will need to be shortened. Use same year Chevelle frame adapters for the motor mounts. TAZ

You'll have the fastest '69 Cutlass in town

The driveshaft will end up being a pain I think. I haven't got the foggiest idea where to have that done around here. I'm not too far from Detroit and Toledo though, so I'm sure there is something out one of those ways. I'll have to take some measurements once I get everything bolted in. When you moved the trans mount, was it a simple, "drill four new holes" or was it more involved than that? Modify the crossmember?

Now you wouldn't be saying the Olds motor isn't up to snuff against a BBC now would you?

Here come the Olds die hards with their pitchforks!
I probably would have just rebuilt the 350 Olds he has, it's plenty for his needs, but it's like 2-3 times the cost of a Chevy. Not worth it in my book.
