thor's hammer ignition and mileage

[KasaRyan at aol.com]

I am currently having some mileage problems with my new engine.  I burned a 
new chip with the proper 713cc/cyl instead of 784.  Everything on the 350 is 
the same as was on the 383.  Same cam (degreed straight up and dead on) 
heads, int, exh, compression, Ign. timing, etc.  Just smaller. 355 not 383.  
Anywhoo, before at 70 mph I was at 2350 rpm, 15% throttle, 1.86V map. 127-129 
INT. Light accel up a hill on cruise brought me to 2.25V map.  Now a 70 mph 
cruise takes 19-20% throttle and 2.20V map.  slight accel raises me above 3V 
MAP.  still 126-130 INT.

  My mileage sucks too because of the increased load or something.  The only 
thing I can think of being different is that before I used RC12YC plugs 
gapped at .050, the new ones are gapped at .035 out of the wrapper.  I have 
an accel 300+ and hot coil, so I guess the only thing for me to try is to 
open the plug gaps.  I couldn't find a leak anywhere.

Can anyone help me out.  I talking less than 10mpg, and that is no fun.

Thanks for listening to my electroyappin!
