Hi all, i'm new to this forum as you can see by the count. Just a quick qustion. I've searched all over this site, and a couple of others. I'm looking for a realistic number for what the stock VQ block can hold. I know the rods and pistons aren't too hot, but i was wondering more about the block itself. Any help would be great thanks!

 

BigBri is holding about 550 rwhp I believe was the last count on a stock bottom end. Is that strong enough for you? I would be comfortable with 450 rwhp as a reasonable limit.

Yeah, im only looking for about425-450 rwhp, im just curious, and want to make sure ive got a good safety margin, thanks!

 

I think someone crossed 700 before they ran into problems with head lift but i may have just been dreaming
