Could to much advance ruin the engine performance??

I agree Steve, I wish you could advance the timing at will!! would be nice!

Yea, Mike Leach will give you whatever advance you want, maybe I'll send
mine
back and ask for 5 more degrees???? (10 Total degrees) hmmm??? got me
considering it now...

 I'm sure they are talking about Mike Leach Co.
 
 Milling the heads is an inexpensive hop up. Only problem I see is the
 availability of Head gaskets and head bolts. Are the 4.7's torque to yield
 style bolts???
 
 I wonder if you can tell by a cranking compression test whether your
 particular 4.7 was low or high spectrum on static compression. I can run
 the test, but I wouldn't know what the numbers meant.
 
 I wonder if Leach would put a little more advance in his custom flash for a
 customer. I also wonder what would happen if you had an MP PCM and then
 added a Jet stage 2 to advance it even more! It's ridiculous how far you
 have to go and how much you have to spend just to bump up the timing!!!
