max hp and torque for a 2-Bolt?
I've rebuilt my 350 (2-bolt) motor recently, but now I wondering how much can it handle? I'd like to push 350-400 hp, but does anyone have any idea what a 2-bolt generally can handle? Thanks!

they replace the 2 bolt cap and they have to extra holes at an angle you drill into the block and it supposedly stronger than a 4 bolt

oh I see, I wish I would have known this before building it.

So do you have any idea what this block can possible handle?

Build the engine to make power no higher than 6000 to 6500RPM and you should be fine, spin it faster than 6500 and your rods and crank might give you problems.

Most everything I've read, stock 2-bolts are good to around 430-450 hp at 6000 rpm. That hp rating starts falling off quickly as you spin it faster and faster.

I've seen many 2 bolt engines spin around 6k RPM on a dirt track and not have any bottom end failure.
