Question 428 block strength


I got a 428 engine totaly rebuilt and I got a question about the block.

As I understand it is a 1966 Truck block
Marked: C6ME

The engine made almost 500Hp on the dyno.

Is the block safe for that power?

What are the power limits for this kind of block???

Re: 428 block strength

It's kind of a loaded question. That block was designed to run at 425hp without issue. Many have done 550-650hp with 2 bolt mains with no problems. However balance and rotating assy weight can come into play. Build quality too. But you should be ok at 500hp mark if well built with good parts.
