I have a V2 on a 111LSA that I planned to use in my LQ9 with a T56. I've always been researching, of course after the fact, and the DCR will be lower than I expected at 7.55. Am I going to have a pig on my hands with this low of a DCR?

I expect the 6.0 will eat more of the cam than an LS1 will, but I really didn't want to swap heads at this time. With 11 degree's of overlap it bleeds off much more than I expected, but upon researching further there aren't a lot of cam's out there that will give a DCR over 8 in an LQ9 without swapping heads.

Thanks,

What is the ICL on your TV2, 111+?

because 111+2 is 7.89
111+4 is 8.02

and 111+0 is 7.75

So I dunno where you got 7.55

Here are the specs I'm using from the cam card. Let me know if I'm doing something wrong.

232 234 @ .050
281 283 @ .006
111 LSA 110 ICL


I get 11 degrees of overlap at .050 with a DCR just under 7.6. I'm also using 1.5 to account for the flattop piston not being truly flat via another on this forum from speedtigger.

On a 110 ICL I get 7.82

Thanks Pred!!

Will the car still be a pig with the 7.8 DCR compared to the optimal 8.5-8.8? It's going in a 66 Chevelle with 3.73s in the back. I know driveability with the 111 LSA and 11 deg of overlap will be in the tune, but I'm concerned that I've got too much cam due to the low DCR.

No, it should be fine, with the right fuel and spark.
