[Spits] Some 1500 questions

[Mark J Bradakis]

Just plug the injection ports.  You can use standard pipe plugs, though
flat brass with a hex opening look a bit neater.

On the 9:1 1500 autocross motor I built I ran regular gas on the street,
no problem.  For events I advanced the timing about 4 degrees and used
a mix of about 1 gallon of 110 octane leaded race gas mixed with 5 - 6
gallons of regular unleaded.

For street use you should be fine with an 87 octane fuel in a 9 to 1
engine.
