Re: Chevy Big Block
I used to have a 1968 Impala with a small block, I was told that the big block 427 was a drop in replacement and would not require any modifications other than stiffer springs for the front end. So your 454 shouldn't require any modifications either.
Yes the TH-400 has an electric kick-down for the Drive to 2nd gear change, the Quadrojet carb had a push button on it that was activated when the throttle was pulled back far enough, it worked very well.
