Maybe I've learned a good lesson . . .
Here is the 68. My first car was a 69 and I did a 318 to a mid 70’s 440 swap. I told myself I wasn’t going to do that again, but about 6 years ago I pulled a 68 440 w/727 out of a C Body. I have since cleaned up the block and turned the crank. It was frozen, rough and rusty and hardly any of the parts are usable, but maybe I’m warming up to the idea again. With respect to my question above, maybe a torque converter with a 2600-2800 stall may be all she needs in the short run?
