I have a ly6(6.0) that the heads were milled .40 ths the compression should be between 10.5 to10.8 the cam I was going to use is compcams lsr 269 219/227 .607/.614 on a lsa 112 how will this run

 

That cam will run fine, with the intake side being under 220 it should make power everywhere. What converter are you going with and in what vehicle?
You need to match it up with a good aftermarket converter as well. Might want to get gears later on too, depending on what you already have and if you have a heavy truck with heavy wheels/tires.

 

I have a triple disc circle d 3200 stall for gears I have 4.56 gears and 35" tall tires

 

In a 2004 tahoe I'm looking to get torque to get it moving

 

I would check piston-to-valve clearance with that cam and milled heads. Just as a precaution.

 

True that, only safe way is to measure.

 

Yes I will but how will run

 

Once tuned, it should run really well with a fairly broad powerband, and will also work well with your Circle-D 3200. Do you have anything else done to the heads? I wouldn't let that .6xx lift go to waste, and get a nice port and polish or CNC job. If you have the dough, you should give Richard at WCCH a call and discuss your options

 

Well i have some light p&p done on the exhaust side

 

ly6 have dished pistons, its should be fine with that lift/lsa
