My thoughts exactly. This is looking more and more like a "maximum effort" racing engine.

Yep, for the class I'll be running it is. I'm capped at maximum displacement, so anything I can think of that can give me an advantage I'll try.
A turbo would be like giving up and would give me a huge handicap. Installing an LS will also be like throwing the towel plus an even bigger handicap.
Replacing some engine parts is still a lot cheaper than an EFR turbo + hardware or an entire built LS swap.
Now that leaves me as a driver to make up for the rest. Its more fun that way, I love being the underdog!

That is what I thought he was building from the beginning of this thread.

LX9 cranks use a 24x LS1 reluctor wheel, all four that I have owned were forged. AFAIK, none of the pre-LX9 cranks were forged from the factory.

Ahh, ok.
Did the LX9 have 2.000 or 2.250 rod journals?

Is it possible to drop the LX9 crank in the the 3.4L block? Of course, changing rods and make the MS work the the 24x signal.
Thank you.

I'm not the expert on that in particular, but I haven't heard of a reason it wouldn't work.
2.250" journal is the same size as the Chevy 4.3 V6, so it's not such a weird size.

LX9 crank should fit the 3.4 block with some minor clearancing of the pan rail. You could offset grind it if you wanted more or less stroke if you cut it down for a 2.0 rod journal. You would probably want to have the bearing surface rehardened afterwards though. You can find more info on the LX9 cranks on the 60degreev6 forum
