Quote: To be honest, your 5.99 in the 1/8 is a 9.40 pass and figureing 3200 lbs thats gonna take 720 hp and to get that 720 hp you need right about 320 cfm head flow.... I dont think you can get that from a stock head
you are probably right about the 320 head flow. i have never seen a factory head flow that much. we had a set here that flowed 305 but i dont think you could have gotten 1 more cfm out of it. but i had a 70 dart that weighed 3310 that had a 400 stroked to 500. it had mild 906 heads that flowed 256 and a comp .650. that car had spinning/ chassis problems like you wouldnt believe. i only made 4 passes and it went 6.59. it was nowhere near maxxed out and would have been 2-3 tenths quicker by hooking it. everyone said those heads were going to choke it to death til they seen it run. thats what got me to thinking maybe its possible to run the 5.99 with factory heads
