x2 on this one.. ur truck is light and can afford a bigger cam then the 212/ 218.. altho thats a great cam.. i had it and i loved it... keep the lsa low u dont want to rev to the moon.. 111-112 imo

 

It feels like I may have lost some low end but seems to "kick" a little more at 25-2600 on up. I definitely need to retune. I'm manual but you auto guys would probably see good results with a 3k stall.

 

i have done some reserch today and im starting to lean towards the tr 220 i think. they have a pack deal on there page with the cam,valvesprings and pushrods for 599. and yess i want to keep the revs under 6300 on this motor

 

If you want to rev less than 6300, I agree with the opinion of Grey Matter, the comp low lift will get you great power to 6300 and minimalize the loss of torque. The 220 would be good for 6500 to 6700 imo. I think without revving that high that youd be leaving power on the table

 

Get a custom grind specd out for u. If u go to small ur gonna wish u went bigger. Just my 2centz im on my 3rd cam. I started with the 212 went to a 217 and now about to install a 222... got better times everytime.. and since ur 5 speed u don't need to worry about converter. And don't worry ur engine can hit 6500 np. Just make sure its not all day everyday. Lol

 

i just see a 220 being to much cam for a 4.8 because it will be lacking lowend power
The 4.8s already have no low end and this cam isnt gonna help

say 5th gear n the interstate at 70 mph about 1700-2000rpm and you wanna pass a car probly gonna have to down shift into 4th instead of just rolling in the throttle.
With a torquey cam like a 212/218 it would pull in 5th

 

cough..... motor swap...... cough....

whatever you do dont go to big... and dont get roller rockers... not worth it...
what i would suggest is to buy a GOOD set of valve springs... dont risk it....

cody what LSA is your cam???

 

I'm thinkin a 212/218 with about 111 or 112 lsa would work fairly decent in my 4.8 ecsb... just need funds lol

 

114+2 lsa
