LOL! That's funny, I'm glad you like them hah!
Not yet, but I am working on it. I'd be glad to lay out some pricing for you regarding cam cost, spring cost, push rods, and other items I recommend during a cam installation.
Lift isn't always an indicator of aggressiveness. I can easily design a lobe that is .580 lift that has more jerk and higher acceleration rates than a .610 lift lobe. Ramp rate and lobe intensity is much more important than lift by itself.
I've done more 5.3 cams for stock stall converters than I can count. Most of my customers that have camshafts and stock converters are on a budget, like most of us are. Some just have bigger budgets than others!
One of the packages I REALLY like is to custom grind a cam for the stock converter and 5.3 engine and use LS6 beehive springs to keep cost down. The other side benefit to a LS6 spring is it will last much longer than an aftermarket beehive and aftermarket dual springs.
The LS6 valve springs I sell for 79.99 and replacement one piece seals/locators for 25.00 dollars. Push rods would be 95.00 dollars and the camshaft would be 450.00 dollars.
Now, my cams are more expensive than some on this site and in the industry, but they're all ground on 8620 billet steel Cam Motion cores. They are hand polished and cam doctored so IMO you're getting the best product you can in regards to the camshaft itself. Comp does NOT hand polish their cams and although they do cam doctor them, they aren't as interested in accuracy as Cam Motion. Kips camshafts are within tenths of a degree to what they're supposed to be. I've seen Comp Cams up to 1-3 degrees off, and Comp tell me that's as good as it gets and no one can do any better...
I would need to know the weight of the vehicle this engine is going in, the rear gear ratio, tire size and usage of the vehicle before recommending cam specs for the engine.
I hope to get to work with you Parrisw in the near future!

So far weighs approx 2000lbs, will be a little more with this engine. I don't know rear gear yet. But would think 3:55 at most, it's light. Tire size unfortunately probably can't get more then 235 in there. Likely 15". That's about all I can tell you so far. I don't mind changing converter.
I don't have a Trans yet. But looking at a 4L60E out of a 2000 chef truck V6. Will it work? I just started another thread about that. I don't know what gear yet either. Will likely have to swap in a different diff to handle the power. Car weighs about 2000lb. Going to be a driver. Maybe hit a few autocross with it too.

For a driver and occasional autocross in a 2000 pound car equipped a 5.3 with a rowdy idle the cam below will be a ton of fun. With a 2800-3000 stall it will be a rocketship and have a very wide flat torque curve. It is very similar to the tried and true ASA cam, but with better designed cam lobes for more power.
Here is the full rundown on this cam:
XA226/365-XA236/350-10+4
226/236 .620"/.595" 110 lobe center angle with 4 degrees of advance ground in.
For Hot Street or Street/Strip in 5.3-6.0 liter cathedral port engines. 3000-6400 operating range. Lopey or Choppy type idle. Best for 9.5-10.5 compression ratios. Best performance with 3000-4000 stall conveters. Recommend 3.73-4.56 gears. Can be used with manual and automatic transmissions. 1 3/4 headers recommended. Can be used with beehive springs, but our dual spring kits is recommended as well as hardened pushrods.

Don't suppose there are any vids around with that cam? Would love to hear it.
Don't let the lift scare you. .600" lift is average for an aftermarket LS camshaft. These engine are a whole new world. .600" lift in these is like .500" lift in the old flat tappet engines.
Yes, you are right about the gear ratio and weight. At 2000 pounds, you could run a 3.00 to 3.50 gear no problem.
I did not have this exact cam, but I used to have one almost identical. Here is an idle clip:

LOL. I knew you were my kind of guy. The exhaust is 3" dual with an x-pipe and Dynomax Super Turbo mufflers. They are surprisingly quiet when cruising but still sound killer. They flow like crazy too. I have uncapped the exhaust at the track and the car ran the exact same times with or without the mufflers.
