Well if the deck height is really 9.0 inches allot has been milled off. Stock is 9.59-9.60 so approx. .060 is milled off. Completely filling the water jacket isn't good for a street engine at all. Means no coolant can now flow around the cylinders. It's my understanding that you only do that on a race only block. You can partially fill a jacket on a street car but I'm not sure how much is ok. Maybe if I'm wrong somebody will correct me.

That's a whopper of a cam too especially with stock heads. Unless your running a 4,000 stall and low gears it won't have much guts on take off.

I'd keep looking but that's just me.
 
A half fill of the water jacket would be OK for the street.

I believe that Badger only makes cast pistons.

i would think that this has to be a miss print because that is .600 which would be over a half inch.
 
That is a lot of cam and... Schubeck lifters - tried TWICE .... I could not get them to live on he street - kept wearing down the lobes.

This is exactly the stuf I needed to hear. I didn't know about the deck height or the water jacket filling...this engine is not for me, that's for sure. Thanks a lot!

Stock stroke, stock bore, badger pistons and a hard fill????

Those things don't go together in my mind.
 
Sounds like it might have had a crack somewhere... in any event, filled blocks mean one of two things. You're running alcohol for fuel, or it's a coffee table.
