I would agree.

Got it back together last week couple changes ported LS2 intake (for strength) and replaced valve seats ended up with a slightly lower compression. Still need to work out the tune for the changes but it's getting closer.

Since you swapped to the TH400, can you still manually change gears 1,2,3 with it?

What auto trannys can you do this with if setup that way? (sorrry for hijack)
Thanks

Car looks amazing, love the orange and new rubber, get some vids for us!

So you swapped intake mani's for compression? how does intake change compression or did I read your post wrong?
Any noticeable changes with ported stocker?

Yea its a manual valve body so you have to shift it manually there's no "drive". I think any auto with manual valve body you have to shift manually. I know it's common with a powerglide and TH350.

I worded that bad I swapped intakes because I cracked the FAST 90 under boost. The lower compression is because I had material removed from the chambers when I got the valve seats fixed and I went to a thicker head gasket.

I hear a ported ls2 = 12hp over a non-ported ls2 n/a. I have no idea what it will do to my power I changed so much stuff it will be impossible to tell.
