Re: On the fence about selling my motor..
Ok.. I'm biting the bullit and buying the 408.. It's coming throttle body to oil pan and will drop right in my truck. The only things I'll need to do is put my electric water pump on. I'll be pulling the cam out of it however and replacing it with a bigger one. It has a little 224@.050 with a lowly.563 lift. I think I'm going to shove a 254/270 @ .050 with .646/.600 in it. I think I'll pick up a good 50-60ftlbs and 70-80hp over my current combo.
It is a 9.5-1 motor though. So the question will be, do I pull the slugs at some point and bump the compression or, do I turbo this one too? It was originally put together with that intention. I don't think I'll gain a ton with more compression. I'll be able to run a smaller verter too and take more advantage of the TQ the N20 will create.
