Boo, Thanks.
In my early years I worked on some of these. On researching I have come to realize it is a maze, with a lot of conflicting info. I have a line on a 55 Dodge 270, but my gut feeling is it won't work for my needs. Hopefully you can confirm. I once had a Plymouth 1957, 277. It was a "A" block poly. At least I know it was a poly. My gut says I need to stay with that block style, Dodge? Plymouth. in order to use the torque-flite transmission bolt pattern.
What I want to do is put a poly in front of a 46rh and put it in our Dakota. Don't ask why, its just something I want to do, maybe nostalgia . So I am assuming from all I have read and what you are saying is I need an "A" block, 227, 301, 303, 318 from 57 to 66. I have a line on a 318 Plymouth, I believe is a 1958 engine. Could use some help figuring this out. Separating fact from fiction in this situation has become quite difficult. I concede to a wiser mind.
Thanks
