I call a real cam something well north of 7000. 6600 is street stuff.
9.25” rear axles are weak too. Why that isn’t the first thing everyone ditches is beyond me.
But yea. Trying to sound smart. I’m not the one spending a fortune on a brick to go 12s
Been there done that in my younger days,cams with shift points above 7200 sound great idling and at full throttle,but aren't really condusive to being a nice driving street cam,lol. My old 68 Z went 10.70's with a 433 BB and a 125 shot shot way back in the early 80's,as a kid I thought it was great,but now I wouldn't put up with a cam with more then 256 dgrees of duration,like I would back then. 4.88's and a 4,000 stall meant the car knew where every airport was.In those days 110 Avgas was you're friend,mixed with 1/2 a tank of farm Purple fuel.Farm purple back in the early days was the same as what you could buy in premium fuel at the pumps,and was a good choice to mix with avgas and keep a big cam/12.5-1 compression big block happy at 7200 rpm.Then I went the opposite way with my old low 11 sec 401 Hornet,it was a low compression /big cam combo,that I could fill up anywhere,but it needed all kinds of rpm and convertor to be drivable on the street,and it ate cranks about twice a summer,lol.Still questioning why you had a horsepower eating 727 behind a little 340,if you were on the ball,you would of had a 904 behind a 340,and went faster,lol
The limited slips in the 9.25 ZF's are weak,but you can circumvent that by sticking a True Trac unit in them. If you swat a curb sideways hard enough,you can break an axle,but that'll happen with the 12 bolts and 9" Fords to,just don't slide it into a curb and the axles are good for a fair bit of power. There's always the aftermarket for upgraded axles to,if you do start twisting an axle,but that applies to the other guys diffs to.
