LOL see I told u id find it
Thnx ckhd,thats the one i was looking for

Zumo · 11-26-2002, 11:00 AM

I feel like an idiot. I used to know all my trannys. I can't see how I thought it was a th350.

So now. What are the pros and cons of the 400?

crazy longhorn · 11-26-2002, 12:39 PM

Pros & cons? only 1 downside that i see, they take a little morepower to run than a 350t. To the good side, they will handle a healthy BB, or a "hot" sb, in pretty much stock form! I have a 400-2 transgo shift kit, & a TCI converter in an otherwise stock overhual. The 400 turbo has had a pretty warm 455 OLds , & a 425 cad in front of it, then gutted & put in a Chev case with nothing but seals & gaskets, & now being torchered by a 383 chev........just like an old timex

Zumo · 11-26-2002, 12:40 PM

Cool.

Another question: Was this a stock option in 68?

crazy longhorn · 11-26-2002, 12:44 PM

I think it was.....but havent kept up with options on the trucks. My 69 had 1 , & I know they showed up in the cars in 1965.........

Yeah, they came from the factory in these trucks in '68.
