how difficult to convert from PG to turbo 350 in a '64 SS hardtop?

anybody in the group done this before? Would like to keep using the stock shifter/console. Still running a 327. Clearance issues for shifter? Which neutral safety switch do I use or do I have to modify the original switch? I have the kit which changes to a cable, has new shifter detent, etc. Is this even a possibility to do without difficult mods? Thanks for any help.

Yeah, we're runnin' a little bit hot tonight,
I can barely see the road from the heat comin' off,
You know what I'm sayin',
Ahh, you reach down, put it between my legs 'n
ease the seat back,
She's runnin', I'm flyin',
Right behind in the rear view mirror now,
Got the fearin', power steerin',
Pistons poppin', ain't no stoppin' now,
PANAMA!

Its a very easy swap. Shifter linkage hooks the same, trans xmember stays in the same spot, and all you need to ad is a detent cable for passing gear.

Your just jealous because you can't hear the voices!

Super easy swap...done it a few times.
Same length, same driveshaft yoke, same trans cooler lines, same speedo cable, same flexplate and starter.
Just have to run the kickdown cable to the carb.

Re: how difficult to convert from PG to turbo 350 in a '64 SS hardtop?

thanks for all the input. So I can use the original neutral safety switch for the powerglide or do I have to change it to something else? I had a feeling it was an easy swap, but that switch is the one I was unsure about.

You can still use the original neutral safety, park reverse and neutral basically stay within the same positions, the only issue is that the 1st through D are squeezed together into the old 2 position area and don't line up 100% correctly. The above post can correct this, I just count the detents as to what gear I'm in with a 2 speed to T400 conversions.

Thanks, Troy, for the link to Shiftworks. I totally forgot all about them! Time to place an order

When I switched from PG to TH350 in my '69 I had to do some cutting and welding on the shift linkage between the frame bracket and trans. Also had to do some bending of the cooler lines. Added a TH350 kickdown linkage too.
