I got this old Special. Didn't really need it or want it. It has a V6 engine with auto tranny. Is there anything I can use on a V8 car? What kind of tranny did a 6 cyl. have? Wondering if I could use the converter in a T350 or 400. Would it have a low gear in the rear? This thing has not run in 10 years. I only looked at it for 5 mins last year and this year the guy begged me to buy it, so I did. Now it has been hauled in to my place. The wife is :rant: :rant: :rant: . It must go soon. Thanks in advance.
V6 shares the ST 300 trans with the small block V8 cars. That torque converter is a switch pitch so it will not work in a TH 350 or TH 400. Chassis and body parts obviously swap. Are you going to part it out, if so how is the grille>>? :Brow:
Thanks for the info so far. What year T400 would it fit? Just the earlier SP ones? Now about the car. I don't know what to do with it. It is complete, but has rust. Quarters are bad. Since it has sit outside with flat tires for a decade, I would assume the floors and trunk are weak (not opened the trunk yet, and never pulled up the carpet). I do have a clear title, but assume it is only a parts car. Does have a complete grill, but after closer inspection, I saw a crack in the center. What do you think? Should I part it, sell it as a resto. or push it to become a race car? I might take some pics this weekend.
I think the torque converter will only work for the two speed SP (ST300). Pretty sure the ST400 used a different converter. Up to you whether you part it, if you do though, there are plenty of '67 guys on here that need parts. :grin: Forgot to mention if it's a 2 door or a 4 door? If it's a 4 door I wouldn't recommend dumping money into it. If it's a 2 door you could do a big block conversion fairly easily (or make a GS clone). Fender vents and hood scoops and it's pretty close...
Well, I will have to figure it out. It is a 2 door hardtop car. I don't want to sink any cash into it. Got too many irons in the fire. You may see it in the for sale section soon.
gears If its an A/C car it should have 3.23 gears if not it would have 2.93. (At least that's the way it is for '66 so I would think '67 would be the same)
That V-6 torque converter will fit the ST300 and ST400.....in addition, it will give a higher stall rpm when used on a V-8! The 65-66 GS used a converter similar to the 300 V8....it'll give a higher stall than the converter used in the BIG Buicks with a ST400...... Rear ratio...I show the same info as Mike posted (for a '66).... IMHO, Specials make great drivers, or race cars.....since there's no fear of hurting the value of the car by modifying it....
Thanks Mike and Walt, I thought the stall would be better than a stock big block one. Now, what years did the ST300 and ST400 reside in Buicks? Is the 300 similar to a Turbo 350? I have a 67 Riv tranny that I hope the converter would work in. Guess it would work well with a slightly larger cam. If the rearend would have had a low 300 ratio gear that I needed......
Check the driver's side of the trans, it should have a electrical plug. If that plug is a 2 prog then it is a sp trans and if the input shaft is an inch long it should work.
ST 300 Convertor willWork in 400 with switch pitch! I have switched these convertors in 67s before. A Super Turbine 300 convertor will work in a 400 that is switch pitch. Where's this car and what do you want for it? Thanks Jim N.
