Hey guys, I didn't mean to start a war here. Just wanted to go a couple seconds faster. I'm looking for all the flow I can get from the 440-1s. The motor's 572 inches with over 14-1 compression and with my new cam and rocker combo, around .780 lift. I was hoping to go with B1 MCs but just lost a big chunk of my income so now I need all I can get from my old heads without breaking the bank. I run Super Gas @ around 146 mph and brackets at around 8.90 and 150 mph, but wanted to see something like 8.60 - 8.70 at 155 or more and SG @ over 150.
