Hotcam setup buying a hotcam soon (i've heard the negative reviews, let's just keep those to a minimum) along with ls6 springs. I'm now wondering what are the best rockers to go with this setup? obviously the heads are stock. Ratio? also, roller?
i know this cam is extremely mild, which is what im looking for. is a converter upgrade even neccesary? what stall?

Minimum a 3600 stall, anything less really isn't worth it IMO, will need a trans cooler to keep the trans temps down also. Yank, Circle D, Vigilante are all good company's for converters. For the rockers just do the Comp trunnion upgrade, its the most reliable and there is no need for aftermarket rockers in your case.

correct me if i'm wrong, but a 3600 stall speed seems insanely high for a car that will have a very mild camshaft. when i did the math, i was thinking somewhere in the 2500 range. Most of the power is going to be made at relatively low rpm's. again, i'm no expert..which is why i posted here in the first place...haha.

go at least 3200...2500 is barely over stock which is around 1800
the Yank SS3600 is pretty much the go to choice for a street car that doesn't want to give up a lot at the track, but if you are not ever planning that then you could get away with one of Yank's budget lower stall converters
either way the car will pick up more from the converter than it will the cam

The Hotcam would be one of my top choices for an application where longevity and low maintenance (specifically meaning valvetrain, as compared to higher lift/much more aggressive ramp rate cams) are top priorities; you can put it in, tune it, and forget about it for 100k miles.
I agree with the above. 3500 stall speed minimum. 2500 is not even the right choice for a 100% stock LS1, and would be a complete waste. I would pick something in the 3500-4000 range for a street LS1 with a hotcam and the usual bolt-ons. I would pick (and have picked) that same stall speed range for a stock LS1 cam as well. For much bigger cams that fall into the "aggressive" category, for best results you should consider 4000rpm stall speed as the minimum.

Of course, for a max effort race car you'd want to forget about street manners and pick the stall speed that results in best ET with no consideration for anything else. If this was your object I'd say that 4000rpm+ should be your minimum.
For a street car, a 3500 stall might sound "big" to some people but if it's a high quality unit, most get used to the street manners in a matter of a week or so. At that point, many people find themselves wishing they had gone higher. Once you reach lock-up (around ~45mph, but this can be changed via tuning), rpms and driveability will be exactly the same as a stock stall speed. A high quality (such as Yank, PI, etc.) 3500 stall can feel "tighter" at part throttle than lesser quality units with lower stall ratings - so quality does matter.
For stock or mildly built LS1s, stall speeds in the ~3500 range represent a nice compromise between reasonable driveability (for all but the most sensitive drivers) and explosive acceleration gains.

3500 stall seems high to me too. Guess it depends on what you want it to do.
My buddy did a hotcam 2800 stall, and it was a very nice drive. Didnt put down any spectacular dyno numbers, but the car was considerably faster. Beat a lot of other guy with bigger cams. Car was just consistently quick, while being a nice DD.
