Ok guys
This denali has H&C 220/560/114LC LTs UPD C/back EFI live.Radix.Ran strong for a **** load of miles, engine lasted about 12K with the radix.Do we go 408? go 370? OF course we will need larger injectors,If we bring the shift points down and run some TQ managment you think the 408 would be a better option?

Other option is put back stock sell it and replace it with a 07 avalanche.Has anyone done a stroker?the 5.3 wont cut it,need power options.

 

Its got a 6L in it right? If some forged rods and pistons reuse the cam and call it good that RADIX going to be weezing hard on a 408.

 

I talked to Tever not Jason at Texas speed.He said go 408 over the 370,I mentioned I didnt think the radix was enough,he almost made me belive he wasnt familuar with the radix abilitys

 

Go for the M122HH since you have everything else needed for the system.

 

Everybody knows the radix is running out of breathe on a 6L much less a 408

Think about it he makes alot more money off of you if he sells you a 408 shortblock then if he sells you rods and pistons. 370 will be cheaper and will still make the radix useable, the 122 upgrade wouldnt be a bad idea either but I still would only go with a 370, the 122 is still only a 2L blower which is small for that many cubes still.
