If it is a 4 speed then it will be a 465
700R4 never came factory behind a 454.

I had a 1980 C20 Crew Cab in high school that had a 454 and we pulled the 400 and put a 700R4 in it and it handled it fine. Hell my grandpa pulled his 30 foot fifth wheel with it all over the country and never had an issue. No overdrive was killin what little mileage the 454 would get.

true about the mpg...one nice thing I do like about my 700r is that super low 1st. Sure makes it nice since my gearing is, well lacking.

isn't the 2wd manual the sm420?

In the older trucks they are. In the '73 on up trucks, they are the 465's but some trucks ran a 3 speed manual tranny, too, along with some very rare trucks in the 80's that ran a 3 speed with an overdrive to make it a 4 speed.colbystephens said:

No. The 2wd is still a SM465.
Now if we are talking a '67 or older truck, all the 4 speeds were 2wd SM420's, 4x (divorced xfer) or 2x.
