Thread: Ported Cases

Is this needed or done by most of you that have 1390 setups?

improves acceleration - mostly raises mid range HP
the 1390 pistons will hit the cases so the cases have to been grinded on a bit to provide clearance - easy to do - you can even do it yourself

Yea, I figured I would have to do that. I also remember reading it some where. I think the 1390 Group-K write up. I have tools for taking off metal and an air tool for it so that will be easy.
Thanks for the info, just wanted to see what the whole ported cases thing was about.

After hearing several sides on this. I opted not to port my cases figured I could always do this later if I feel the need.

It costs virtually nothing, so if you're sending out your jugs to get done, why not get the cases ported?

I just paid Lowell 130 dollars to do mine. Have not really pounded on it
next to anyone . Elliott rode that ski at the Tampa drag races against
some tiny fast people and with the set up on the ski it sure ran faster than it should have.

I guess my point, which I didn't make very clearly, is that I have had success with my setup (which includes ported cases) and would recommend it. And since Lowell charges next to nothing to do it, I would recommend it even more. Just my two cents.
