Smaller cam, more stall, Gears Not really sure

[Gus]

I love how my truck sounds but you can check out the video at the following link and see there is quite a bit missing from the bottom end. its a 4.8 in a ecsb 4x4 so its heavy. Ive watched the video a lot and dont know if I should go if the 3.42 to 4.30 would be best, a 3200+ to replace the 2800 I have or smaller cam would be most economical and get the best gains http://youtu.be/NCIzOrbRNgc

Gears and stall. you'll need everything you can get with that 4.8

Yea I wish I would of bought a bigger stall in the beginning but I wasnt really sure the starting RPM on the cam and didnt want to go to big. Now I got to do the work twice and sell the 2800 I got. I think it would be a good choice for someone with the 212/218

I don't mean this in a derogatory way at all, but I wish people would think about LS motors and their setup a little more before jumping into a cam/stall swap. Most people who get into this are scared of a stall the first time. What a lot of people who are new to this style don't realize is that you've got a 5000lb+ vehicle and a motor that likes to rev to 6200 stock. It isn't just any old small block anymore. You're a prime example of someone who got into it, then realized, crap, this stall isn't nearly big enough to support 5000lbs and a small cube motor that likes to rev. Like I said, I don't mean this in a bad way, regardless of how it sounds.

Get a real stall and a set of gears in there and you'll be worlds happier.

Start with the gears. It will make a huge difference. If you still want more add a bigger stall.

Ya it's cool and u have always posted to on my topics with good info. my main concern at the time was towing capability and not really knowing how this cam would perform in a 4.8. I went throught the comp cams book looking at specs of cams that were as close to what i got and comparing their notes for supporting mods. I dont remember which one it was but it was the closest i could find in duration and lsa and That comp had a starting range of 1800rpm which also lead me to my converter choice of 2800 thinkiing it would give me a 1000 rpm of wiggle room to get te engine into a better range. I tried not to go in that blind and actually spent quit a bit of time reading posts on this forum, and pt forum speaking with comp, rci, and I even tried emailing circle d but never got A reply. most of the forum guys with 4.8 were going the 212/218 low lift route which is a completely different animal then what I picked up and the "ls1 hot cam" has the same duration but less lift. It's a learning experience for sure and as mentioned before i love how the truck sounds with this cam. Iguess I'm just going to start saving for the gears first and start there

I think that is a good idea. Gears give the best "seat of the pants" gain.

4000 rpm converter and my gear suggestion would depend on your tire height.
