hi there guys i have a 09 denali with no flex fuel.. 4 and 8 cylinder.. i bought it like that which is wierd i thought all new denali's had this option anyways.. i ordered a stage 3 head from livernois motorsports http://www.livernoismotorsports.com/...t.phtml?p=1536

and now i need a camshaft.. to go with it... a friend of mine recomended me a cam but i dont have the numbers till now.. what do u guys think of these with a 3200 stall from yank... (the car is daily driven)

227/239 .614/.624 115+3

231/243 .617/.624 115+3


regards

 

id go with the smaller one if you are picking one of the two,,, id think a denali owner would like more get up and go grunt than winding the **** out of it... especially with a 3200

 

seems like alot of lift to me,but someone else will probably chime in

 

The lift wouldn't bother me as much as that duration. for a daily driver that's bigger than I'd recomend. Of those two I'd certainly do the first. If you haven't ordered the headers yet I'd recomend the 1 7/8" over the 1 3/4" for your setup. Many times over we've dyno'd both at work and at your power level there is no reason to go with the small tube header.
