how much can the factory block hold again? its a windsor block. Im just curious cuz i have the motor out, and may end up doing a rebuild and have to weight the cost of what im doing. and i know there is probebly many threads on this but i never seem to have much luck with the search so i just dont try much anymore, so if you dont like it....dont waste your time responding, and let the people who are willing to share the answer speak up. Thank you

 

The general consensus is 450hp.

 

i thought that was the rods?

 

im guessing he thought you ment how much can the stock motor handle.

the block will hold alot, what power level u lookin at?

 

mainly if the stock stuff i have now turns out to be to damaged to fix cheeply i was thinking about forging it...and if i do that, im looks at the mmr 900 stuff. i may not make the power for a while but dont want to put good stuff in there if the block cant handle it.

 

Ah fak.. reading owns me. the block will hold up to "800" so say the old guys.. but iv never read of a cracked block.

 

If you want to go much over 400 whp then you need forged rods/pistons. Crank is good to 600 ish hp I believe.

 

stock block with forged internals is supposely good for 800 rwhp or so.
