31psi is low boost these days.
Bman, I have been looking into this and plan on doing the same once i get home, I believe tom revs his 2.3 to 8-8.5k, u have probably seen it, but there is the same thread about strokers on link.

I don't think I have, you have a link at all by chance?

I've got a set of eagle rods and wiseco pistons that are 20 over with about 300 miles on them.

I'm not trying to be an ass, I just want to know. Why are you not thinking of using a 2.4 block? I ask mostly out of curiosity, but also because I see more deck height as a great thing.

Did you spin a bearing?
And I don't want a 2.4 block because I just want to keep the stock block the cars came with. Out of curiosity, what advantage does the taller deck height offer?

Improved rod ratio, less cyl wall loading (scuffing) Rings and compression should last longer.

2.4s DO NOT have better rod ratio compared to a 2.3. They use a 100mm crank, just like a 2.3 and the rods are the exact same length (150mm) as a 2.3. However the 2.3 will have lighter pistons, so it's better for high rpms.
UNLESS you're using stroker pistons and longer rods in the 2.4.

I'd also like to add another fact.
The 2.4's aren't really 2.4's. They're 2.3's rounded up since they're 2380ccs and the 2.3's are only 2300. Meaning "2.4's" are 2.38 liters and the 2.3's are 2.3 liters.

As was mentioned, whether the 100mm crank is used in a 63 or 64 block, the rod ratio should be the same.
2.38 is 2.4 just like our 1.99's are 2.0's.
Anyhow, here is a nice little chart to use as a reference in regards to displacement. The pistons I'll more than likely be getting are 40 over (86.5mm) which when combined with the 100mm crank, show that I'm sitting closer to 2.35 (which does round to 2.4). So switching to a 4G64 block really won't net me .1L more. I can get that same 2.4 if I just bore it out further. The 4G64 is a 2.4 because it simply has a larger bore...

Again, I've done the research on the motor itself. What my question was, is this a good idea considering the rest of my setup. Just want to make sure that with the added displancement and airflow I'll be seeing, will I actually lose power or anything because I'm choking it. Maybe my setup works great on a 2.0, but add that extra bit of displacement, just want to make sure I'm going to kill my setup.
Thanks for all the feedback so far though, keep it coming! Right now I'm just trying to locate some pistons.

Have you thought about going with a higher compression piston since you run E85?
Repost but great stroker info here http://www.kidzuku.com/StrokeOrNot.pdf
