Agreed, you can get a shitload of torque out of a big block, but for the street I trust the reliable 350.

Plus I think big blocks cost to much to build for street applications.

I orginally was going to go with a big block for my Blazer but the small block does what I want it to. My torque numbers are in the mid 400s and for what I am doning with it it suits me.

If I ever build another mud car its going to get a big block, I just have other cars I want to build right now.

That's kinda true, but it also depends on how an engine is built and what the application is. A mildy modified big block with a properly selected fuel injection system can make almost as much power, be more efficient and reliable as a daily driver than a totally tricked out 350 small block. I would rather go for something like a Rodeck forged aluminum block. It might cost a good chunk of change, but it would just as strong, if not slightly stronger than a cast iron one and the weight savings would be incredible. Something like that is way down the road, though. A cast iron one is cheaper, but would serverely compromise the handling of the car.
