and im back... ~1100 miles i think i broke 10mpg on the last tank... first tank was 8.1 second was 9.1..
been pulling timing out like crazy.. up to 10* in spots to reduce the igniton rattle/pinging. on the part throttle where i usually ran 10-15* @ 2500 with no rattle with stock im down to 7-9* still little noisier then stock pistons... it was rattleing like a 6.5 under a load.. also as i pulling timing engine responded better still not snappy like stock was but i have a broke in engine and 45k to prefect the tune...
cruise rail pressue it 20k stock going to bump that up to 26k. it will allow me to get the fuel in there quicker and at a better atomization for better burn.. it was worth ~2mpg on my LB7 in cruise.
while driving.. been thinking the difference between stock and finger bowls... wherre stock has one big hotspot.. fingers has basicly two small hotspots allowing the fuel to ignite faster thuse creating the ignition rattle where the stock pistons didnt.. also anothing to note the bowls are shallower then stock as well making them naturally closer to the head
