170 Slant six fuel injection - HELP

how much power,,
a well tuned carb will get the same power as a well tuned FI system.
The difference with FI is the ease of tuning.
instead of disassembling a carb to change jets or a distributor to change springs, it is done on a FI system with key strokes on a lap top.
The FI system can also self tune itself while running to compensate for altitude and temperature and other changes.
The MS system will allow me to change from gas to E85, you will never do that with a carburetor.
But there is no absolute +power with a FI system,, just saying.

here is the posting that discusses the slant six intake and fuel rails that are available through Gill Welding
