CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? This is what they recomened for my stroker and this is a LT4. can yall give some opinions of this cam????
Well for that kind of rpm in a 409 I would use 3316/3317 HR114 +4. This would give you 288/294 advertised duration and 236/242 at .050. The lift would be .555/.576 with the 1.6 rockers. The lobe separation would be 114 degrees with a 4 degree advance ground in. I think this would be a good choice in a cam for that size motor and would make good power up to around 6200-6300 rpm and still work with NOS.

I want max hp and torque on motor to be at about 6200 rpms(thats where i shift at). I want a cam with goos N/A power but with a lot of kick on n20.

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? Sounds like a good cam <img src="gr_stretch.gif" border="0"> Depending on your head flow numbers a little more lift might be a good idea <img src="gr_grin.gif" border="0">

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? On a stroker, I would NOT be into 114 ls. I would stick with 112. I dont know exactly what lobe series those are, but avoid the Extreme Energy lobes that large on the LT motors. The valvetrain cant handle it.
I guess Im still wondering why you dont want to go with the cc306 cam (230/245 on a 112).
The 15 degree difference in duration will be especially helpfull on the juice.

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? Im really worried about N/A power. Because ill only be on the juice about 5% of the time i drive the car.

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? A little correction.
The comp 306 is 230/244 @ 50.
It is an EXCELLENT N/A cam and performs well on the gas. The lobe design is a bit dated. (circa 95 or so)
But that comp cam that they recommended IS an extreme lobe. As has been noted... they sometimes have probs with the valve train. Sometimes not.
If its set up correctly... the recommended cam you posted earlier is a dang good one.
Good luck. Lift? for an LT1 that is plenty in my opinion.
Again. Good luck.

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? That sounds like a good combo for the stroker. Though it is for the LS1s, MTI has had a lot of success with the "R1" cam, which is a 232/236 114 LSA at .574/.578 max lift. Works very well, and the 114 LSA is not really robbing any midrange torque at all.

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? On a bigger motor you can get away with a litter wider LSA than you might on a smaller motor (sincey ou have more midrange torque, and also because of the later exhaust closing/earlier intake opening since the durations are bigger.
I would stay away from the big comp xtreme lobes - I just haven't seen many people have luck with them. If you do go with them I would run the comp R lifters and a rev kit - with 409 cubes your rpm's might be low enough anyway that it's not an issue.
I think that cam is going to make peak hp right around 6200-6300 or so, though it will really depend on the heads.

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? I have a AFR rev kit and shift now at 6200rpms. If that helped <img src="images/icons/rolleyes.gif" border="0">

If you find a cam that does that, I would be impressed <img src="gr_images/icons/wink.gif" border="0"> <img src="gr_grin.gif" border="0">

Re: CAM EXPERTS This is the cam comp cams recomends for my stroker!!?!?!? Is the hot cam really making power to 6200 in a 409" car? Do you have a dyno? What are the CC's on your intake runners?
If the way your setup is right now is giving you an honest 6200rpm shift point you are going to have a hard time going much bigger at all on the cam and not increasing your shift points.
FWIW if you make peak hp at 6200 you will end up shifting closer to 6500 - if you are going to stick with 6200 rpm shift points then cam the car down a little so you have more area under the curve.
