Title: C4 Converters????
Post by: licketysplit on April 28, 2008, 01:03:45 AM
I am building a 1973 pinto that i converted to a 2,300 with a C4 trans. I would like to find a little bit higher then stock stall speed converter without breaking the bank! Would a V6 converter from a 83 or 84 T bird with a C4 trans work to rise the stall speed? Any help? Thanks Howard

I'm not sure about the T-bird converters, but I just bought a TCI Saturday Night Special converter with a 2000 stall for $200.  I'm not sure if you consider that to be breaking the bank or not.

Hi Howard, I have a 78 v-6 converter if that will do you anything. Fred   ???   :)

Well $200 isn't per say breaking the bank! Whats the part number on the converter? As for the V6 converter, i maybe wrong on this but with the V6 having more tork then the 4 cly it should give a higher stall then the 2,300 converter? As i see it the V6 converter would have to stall higher? How much you asking for the V6 converter with shipping to Bakersfield Ca. 93307? Thanks, Howard

From my understanding the reverse is true with most "stock" convertors.  That being the less power an engine has the higher the stall speed to prevent bogging the car. So, a V-6 convertor probably would have a lower stall speed than a 4 cylinder. But, there might not even be any difference between the two (at least that you would notice).
I don't claim to be an expert so anyone please chime in.  My recollection was from years ago when V-8 cars would use 6 cylinder convertors for better launch.

The one I picked up was from Summit and their part number is "TCI-450700".  That's the converter for the case-fill C-4 1970-1982 with a 2000rpm stall speed.

There is only a $6 difference in price between that one and the pan fill version.

Yes, this is true, as I ran a v6 converter in my 302-c4 set up for just the same reason.  A little higher stall, but not overly expensive since it is a stock part.

Thanks guys for the replys. I have the stock 2000 converter that came in the car. The car is a 1973 that came with a 2000 and a C4, I rebuilt the C4 and iam converting the car over to a 2300. Hmm, maybe i need a 1600 C4 converter? He He.........

That's probably for the v-8 which is not interchangeable with the 4 cyl. (different alignment hole size for starters) More than likely you will have to spend some money and have your converter opened up and modified.

And THAT is why I kept the old converter until after we were ready to install everything.  I wanted to make sure that it would work properly in the application... if it doesn't, I'll have to sell off the new one.

I'll let you know in a few months when we are ready to put everything back together.
