I have the Crane 208/216-.530/.530-113LSA in my 5.3 and it's awesome daily driver and sounds very "lopey". With the idle at about 550 rpms it sounded like a drag car. With the rpms now at ~750rpms, it still sounds very nice. It's a very noticable cam, I get compliments about the way it lopes pretty often. I wish I could post up some sound clips of it, but don't have any way of doing so. A couple of people on here can vouch for me though. In second gear with the 3.42's it put down 286rwhp. With headwork, cut-outs and a 3rd gear pull with the 3.90's it should put down 315-320rwhp easy.

So far my fav. cam was my 226/.535/112. It loped so hard at 750rpm that the truck would shake side to side at a stop light and the antenna would just shake back and forth. With a good tune it drove like stock and put down some good power. 97mph N/A at 4900lb raceweight is pretty good for a stock 5.3L without a pulley.

truck will be driven every now and then so i big nasty cam is what i want. i usually take it to shows and to take my dirtbike around so i guess il look intot he 226/.535/112 what all did you change along with that cam and what did you use

I would give Rick@Synergy a call. He is the one that helped design, install and did all the tuning on it. It definately required a tune as the thing WILL NOT idle without one. LOL I wish I could get that sound back on this new motor

With the 3000 rpm stall it worked out quite well if you want something agressive. With a raceweight of 4900lbs I ran 14.29@96.8mph w/ 2.0 60'.. That was with the usual bolt-ons minus a pulley. With more gearing or a bigger stall my times would have dropped like a rock but 31" tires and 3.73s isn't the best for drag racing.

97 MPH IS GOOD BUT WHAT KIND OF 60' CAME WITH THAT A BIG CAM WITH OUT A CONVERTER WILL BE A DOG OUT THE HOLE.

Who would buy a big cam and NOT buy a converter?? It's kinda like buying a supercharger/turbo without doing injectors... Or buying 4.56 gears a 3800stall and racing on street tires.. Kinda stupid..

As for your weight. 4040lbs in a NBS is stripped down IMO. My RCSB 4.8L with a couple items removed has a raceweight of 4450 (I weigh 165lbs). So wether YOU stripped it down or not it is still a lightweight truck no matter how you cut it and that was my point.

I agree with you that he will need more than a cam to get to 350rwhp for sure. I feel pretty confident I was at about 320rwhp when I made my 96-97mph runs but since I never redyno'd after tuning I don't know for sure. A well tuned cam only setup should be between 310-325rwhp I would think. Any more than that is great but not nearly as common unless you have low drivetrain loss (IE 2wd vs 4wd) or a loose motor.
