Going from 6.0 to LS3 418 changes in tune?

[CactusG8]

I know the maf tune will change.

In the general tab where it gives a value of .75 for cylinder volume should I just do the simple math and put in as close as I can get for a 418?

Anything else that would be critical?

For cylinder volume, no reason not to make it as accurate as possible. The formula, and calculators are all over the net.

I get .85625.

Here's a fun fact: you can change the units.

Alan what are you doing now? New motor? I thought you were merely swapping cams again.

I did not see your post. Sean thought I might of messed up a rod bearing or something. It turns out it is aok. Otherwise I would of just dropped in a stroker.

The only things Sean is going to do is to put a .040 cometic gasket in, the new 227/231 cam, new morel lifters, some new pushrods, and timing chain. The morels are on back order. I will get her back around the 1st of August.

Cool. Let me know if you need tuning help. I got my 224/ 234 cammed car running awesome.
