LS2 based 408 or Iron Block 408 ???
LS2 based 408 or Iron Block 408 ??? Inputs??? I know that the knock sensors work "in theory" if you extend the factory LS1 knock sensors... but have they been proven???
i think the ls2 will get you a 402...
but if your asking for preferences.....it all depends on wat you will be throwing at it....
I would get the iron just for a little piece of mind and the extra, though minimal, cubes.
Im not sure on the knock sensors....there tons of 402 ls2 here...check the dyno section and post a question in one of those threads of just contact on of the shops directly.

You really do not need a 402/408. Get a built aluminum block 347 or at most a 383. That will make more power than you can handle Eric. And you told me when you bought this car that you didn't want to do anything "major" to the engine 
. Not a strip car but maybe twice a year? You want something that will be reliable on the street for several years? The 408 is really a race motor. You would need a huge cam and killer heads to use the extra cubes. Fuel economy would SUCK! I just think a 347 or 383 would be a much better street motor for you.
Fix the transmission.
Buy a rearend.
Get some drag radials
.
Then see what you need.

If you think you can handle the big motor, knock yourself out. You might luck out like BUYAMERICAN did and have a half decent street motor that gets good miledge.
This is really just a ploy by me to keep you slower than me

i would go the iron 408 route. but then again... i am addicted to nitrous and haven't dealt too much with the ls2's. i have heard of fixing the knock sensor problems and things working with the conversion... but i have seen too many nasty iron 408's to look else where.
i take that back... i just read your sig. i would look into a rear end and finishing out a good suspension. i went the power route first and hated not having the suspension and durability to handle it. but then again... it was fun grenading the 10 bolt!

I will be getting a rearend before the motor... Basically...
Stage I - (August)
New Clutch (probably Ram)
Rebuild Tranny to handle 600 ft/lbs of torque
StageII - (September)
12 bolt or 9" rearend
StageIII -(October)
motor
Maybe between now and October, the LS2's will be proven to work perfectly with LS1 knock sensors.
