Ignition choices

The second one gives you better distributor clearance at the wiper motor and firewall

No wipers! LOL....I am just trying to see which will be better in the long run, if I install the MSD now it will require a MSD box/coil it appears from what I have read.
The other unit looks like like it just bolts in, but would it be enough to run a 500+hp 360 next year?
