Balanced, Nitrated 7bolt or just balanced 6bolt crank?

[brain129]

I want to make my motor capable of over 400 wheel hp and I am at the point where I have a choice. Either I get a 6bolt motor and balance the crank or keep my 7 bolt and balance and nitrate it for regitity. just curious of your opinions.

You could either make that with a bone stock 6 bolt and be reliable, or throw a set of rods and pistons in the 7 bolt to make it reliable for 400hp. It can be done on stock 7 bolt but unless you have a very good tune it may not last as long as you need it too.
