What is the current limit of an unfilled sleeved coyote block that is still streetable? I've heard figures in the 1500whp range. At this level is the block a ticking time bomb?

Anything above 1000whp is a risk. Some get luck and some don't. I haven't heard of anyone filling a coyote block yet. I would like to see the results of a full fill with coolant holes made in the filler. I think it would work well.

There are plenty of shops that do full fills on the blocks and dry deck the head. Its just not streetable. Here is an example from MPS:

Cool. Seems like I heard of MMR filling their race blocks after they sleeved them. But I didn't know a lot of shops were doing it. Any idea what kinda power they are making with full filled blocks?

Like I said before, I would also like to see a coyote with coolant holes in the block filler.

Darton Midsleeves aren't very common and don't save the blocks from cracking according to the main guy that does darton sleeves.
