Yeah, that looks like a killer cam. Have you broken any valve springs with that cam and if yes, what springs broke. What springs are you running now, the ISKY single TOOL ROOM cam that MMT is sky high on and looks like a real battle tested spring?
Also, what heads you running and what dyno numbers does that bad boy crank out?
THANKS!!!
I ran that cam about a year ago. Used 918's with it when the stock heads were on. Fantastic upper rpm performer. Power comes on at around 3500, and stays there till about 6550 or so. Made 403 with stock 241 heads, added some stage 2+ TEA heads, and with better tuning made 449rwhp through a Moser 9".
GREAT cam. Made 417 RWHP with a 6 speed and STOCK heads. Ran best 7.2 @ 94 MPH in 1/8th with a fairly slow 60 foot of 1.6 (damn 6 speeds!! LOL) Can does need tuning to idle well but it is VERY strong from 3500-6800. Took it on Power Tour this year.

First off I had comp custom grind the cam on an xer lobe. F1 is typically a lunati grind. I was running 5.3 heads with 2.02/1.55's unported w/ comp 918's and titanium retainers. I never broke any springs in 30k...same springs. I was putting 438rwhp 418tq down through the stock 3.42 rearend and M6. It pulls extremely hard up around 3000 all the way to 7kl It is a beast. Absolutely NO tuning was used to achieve these #'s. With some tuning I could've picked up another 10-15hp i'm sure. Idle was awsome...just loped like a sob. I constantly had people at stoplights rolling the windows down and commenting on the sound 
There should be no question about whether or not to run this cam in a daily driver. The only thing you should think about is whether or not you ever want to spray it. The reverse slpit cams are not the most nitrous friendly cams, so I wouldn't recommend it without serious dyno tuning and programming. Up until a little over a month ago I never had any trouble with my setup....then i broke 2 rods. I guess that's what 94k on the odometer will do to ya

I'm running the F1. I have never dynoed the car, only raced it. At 3500, it has run a 7.20@95. On those runs, the converter and/or tranny were screwed up. I could only stall to about 1800 to launch....that is with a PT4400.
In a month or two, the cam is coming out, I'll be selling it, so let me know if you are interested.

So in conclusion....418tq really had nothing to do with the demise of the motor. The ultimate cause was Hardware Failure, which was not really detectable and is something that could've happened with a stock motor. Now had you asked me did my 11.5-11.75:1 compression stand to be a factor...i would say yes...It put the added stress on the rod that ultimately failed
