66 St400 BS code Nailhead

Hi all,

Curious if there's anything special about a ST400 nailhead bell housing BS coded trans and what is the going rate for a core?

Regards,

 

looks like a Riviera GS code

 

BS should be a desirable core.

 

I would of thought the BJ would be more desirable.

 

Now that's the kind of humor I expect from car people. Lol

 

Hey! I resemble that remark!

Whats worse? Getting the shaft or a tranny BJ?

 

There is value to someone with that bolt pattern, and also with a switch
pitch oil passage. BOP cases are far more common. Bruce Roe

 

I was trying to find the things that were upgraded for the 65 GS transmission... found this:

The 1965 Riviera Gran Sport benefited from an improved transmission introduced a year earlier: the Super Turbine 400. Dick Sweeney notes that the Super Turbine 400 featured a reinforced valve body. These transmissions also benefited from recalibration that allowed the Gran Sport to shift at higher rpm. The three-speed Super Turbine 400 featured four pinions in each planetary gearset, versus the usual three.

from Hemmings, but that is why it is a desirable unit! (He said unit )

 

Hi,

Thanks for the info, any ideas on what they're going for?

I got it with a 425 core so no clue on what condition it's in.

Regards,

 

Since condition & workings are unknown it's only value is core value which would be around $100.00 give or take.

 

I know the location of one if you’re interested

 

65-66 nailhead st400 cores go for about $250 from what I have witnessed. a 65 Riv GS core probably has a bit more value

 

A TH425 being a front wheel drive trans used in Eldo and Toro. Bruce Roe

 

Hemmings, huh? All 400s have 4 pinions, why would that massive cast
iron valve body need to be reinforced? He should have talked about its
switch pitch feature. Bruce Roe

 

Often wrong, seldom in doubt!

 

I believe he's referring to a 425 nailhead core not a th425 transmission

 

Hi,

Yes a 425 nailhead engine, MW code, 704 casting number, rwd trans,

Guy I got it from said it came from a Riviera but never know if its factory or replacement
