well, I just unloaded my 1990 Mark VII that I put a positive displacement (whipple type) blower on. Problem was that in the Lincoln, you had to remove the blower to change the sparks on the driver's side! And the other side wasn't much better. So putting a 292 in my 59 Apache will be refreshing to me because I'll be able to stand in the engine compartment next to the thing to work on it!!! In the end, I got tired of working on the thing, and with all that stuff on the engine, it was hard to fix if one little component in the ignition or induction system went wrong.
Now that lincoln was fast (beat M3's, vettes, etc), and I had it for 100K miles, but it was a case of been there did that.
So in my case, simplicity and ease of maintenance ended up to be important factors. However, I do drive a LS400 with 32v dohc V8 everyday! HA! Go figure.
