I am going to be putting a 6L in the Z with some WCCH stage 2 heads like the ones that grippy has. I think Im goin to go with a 224/228 .580 .580 with a 110lsa. This is what Richard(WCCH) recommended me to go with. It is suppose to have a nice torque bubble at 3000 on up to about 5800. Im going for the race car idle and lots of torque. I dont need low down power cause of the 3000 stall. I will be shooting 150 wet shot on top of that. My cr will be 10 to 1. I would like some feedback on this cam selection and see if anyone thinks this will work for what I am shooting for. BTW the 110lsa is suppose to move the power curve down a little to a more useable rpm I beleive.

Thanks, Cody

 

Ttt..

 

I ALWAYS thought that the smaller the LSA the less usable torque down low. 110 is not bad but you need to spin it a little more to use all of its potential. But damn 110 is alot, never seen anyone with a 110 before. But I would say go for it.

 

That cam will be hard to tune.

 

Yeah I know but I think Allen can handle it. If he can make a 245 6L put out 441 after tuning I think he can handle it. Well the cam specs is what richard said would get my heavy *** truck moving and be good for the juice so I am going to talk to allen a little more and see what he says.

 

Just talked to richard he said the reason for the 110 is to add more mid range torque to my power band. So it will create a torque bubble around 3000 and it will also move the powerband down a little lower so it will keep the power more where I need it.

 

Just something to think about...

If I remember correctly, those heads flow near 85% of the intake. Bolt on a stub pipe and the crummy truck intake manifold and now you're looking at around 90%. This in my opinion, and many others results in a intake crutch in one form or another.

I think you'll benefit from a fast ramped intake lobe, slower ramped exhaust lobe. You can usually see this in max lift values.

If it were my setup, I would use a very slow ramped exhaust lobe and a quick intake lobe. Note that your heads intake flow doesn't give out until .575'' lift and your exhaust peaks around .5''... Again, if I remember Grip's flow sheets correctly.

What am I talking about? Just a few examples using the same sized intake lobes at .05'' valve lift.
1)224/220 .581/.564
2)224/222 .581/.566
3)224/224 .581/.568
4)224/226 .581/.570
5)224/228 .581/.572

The better the exhaust flow the less exhaust LOBE you will need.

 

A little bit more exhaust was added for the nitrous.

 

i think for your application it will work out well. if you're running stock injectors you may want to consider upgrading. other than that i don't think the tuning will be all that bad.
