john, were these motors stock ecu?
or dfi/etc?
i am thinking about this cam, too, for an upcoming motor - i like the wide lda as i expect it'll make good vacuum, keeping the speed density moron happy...
how'd they idle/drive?
torque converter?
noted powerband and shift point?
thanks
mike
ps - get your cche yet?

I used the 9-412-8 in my motor.
My truck still has the stock ecm, but I am also running 009(42.5lb) injectors,and 1.6 rockers, so a custom chip was a requirement.
I can tell you that it pulls good vacuum,around 14-15 inches.
It took a little while to get the driveabilty perfect, but Nolan had it really nice by the 12th chip or so. I think we ended the year at #19.
The larger cam really worked nice once I got the shift points up to 5200. Pulled all the way there.
In my opinion its still a small cam, but light years above the stocker.

The 422 worked out nicely for me. I spun the motor to about 5500 for shifts, all the way to 5700 thru the traps. The fastest runs (not sure if coincidence or not) had the 2-3 shift at 5300 or so.
I think either of those cams will work. McCoy is using a 212 cam (I think) that felt very nice as well. It all depends what you want.. a bit more out of a driver, or a max effort truck. Any cam is going to require some tuning work, how much depends on what you pick, and what ECM you use.

im wondering that too :B
My motor had a stock block, stock crank, 2 bolt mains studded with straps, L35 rods & TRW pistons. The motor got yanked cuz the oil pump pickup fell out and lost oil pressure. Bearings were toast.
I don't advise spinning the motor that high unless you do a buildup with 4 bolt mains, Eagle (or better rods), forged pistons, and a good flowing heads & cam combo.
These motors are grunt motors, but to make them fast, you have to build them to make more HP. IMO, the next step past a stronger stock rebuild is one with better (not crazy) flowing Vortec heads, mild cam (412/422 style) and spin it to 5300-5500 or so (with the rest of the airflow mods). I spun mine high because I felt a 3-4 shift at that point would do one of 2 things 1)break the trans 2) slow me down.
I spun the motor to 6100rpm on one run where I forgot to lock the converter. 11.2 @ 120
Locked the converter, gained 2-4 mph, and .1 faster I believe (that day), and brought the RPM down 4-500rpm thru the traps.
It's nice to have detailed logs of your runs :wink:

that is great brian did you always use the stock wheels on those passes and how were the sixty foot times, i dont know if anyone else here is running lighter wheels but the diff. is awesome i am not even putting the cal tracks on it will just add more wieght , i was spinning the stock wheel and drag radial at the track pretty bad but not any more i cant even get them to spin on the street. i have some pics of the truck if anyone wants to post them i dont know how. jack
No, I was always running ROH wheels, with 245 Nittos all around. Best 60 was 1.62, typical 60s were 1.6-1.7s.
I believe the weight was similar to stock.
My belief is that a 315/35/17 rear and 275/40/17 front will give best traction when used with a solid suspension & good tires.
