Comtemplating buying a '64 Jetstar I, supposedly solid body and complete, 394 that hasn't run in at least 23 years and a bad Slim-Jim. I have seen several threads involving LSx engines and '64 A-body cars, as well as the occasional B-body inquiry. I am aware of the motor mount and a crossmember (?) issue but haven't seen the solutions to those (have searched) as well as driveshaft length. Are there other issues specific to the B-body that would arise in this swap, such as rearend ratio and durability? I had a '64 Dynamic 88 4-door a while back but didn't get into it much...

 

Ok, guess I need to be more specific here...

Which engine: 5.3, 6.0, 6.2? Definitely staying with FI.

Which transmission: 4L80 or 6L90?

Disc brakes are a given...

Rear end ratio?

 

Since that motor and trans setup is in everything from 'vettes to 'burbans, I wouldn't worry much about the rear ratio - high 2's to high 3's will be fine with overdrive.

 

I would imagine that the driveshaft will have to be custom made

 

So the stock ratio should be fine...figured on custom-length driveshaft...

Ideas on engine & transmission mounting?

I was waiting on you to chime in, sir! I woulda googled it as a last resort as I was hoping for info from one who had actually performed such a swap into an Olds...in any case thanks for the link and any other pertinent info you could provide!

 

Just emailed them to confirm application, they said "not that we know of." What is different frame-wise between '64 Olds and '64 Chevy?

 

Never mind...looks like I will have to have some kind of custom cradle...anyone have a pic of an empty '64 full-size engine bay?

 

Just get a junk block for mockup and make mounts.

I still have a 71 Cutlass wagon a few miles away. Motor is out ready for an LS1 if thats the direction you want to go

 

Sorry, I'm not on this forum that much anymore.

I highly suggest you go to http://ls1tech.com/forums/conversions-hybrids-28/
Start asking around there, you'll find far more knowledgable people with swap info.

 

I would add the trans on the back and fab it all at the same time. There are many ways to skin that cat! Good luck and keep us posted!
