I have used this a lot with great results.

Jay is this the same bunch that did the billet FE heads awhile back or a different group? Again not for everyone for sure , but is there a market yes. As we discussed on the old forum , a guy building a 2500 HP engine is not budget oriented.

Guy posted this over on the old FE forum. Says he knows Jay so I hope it is ok to post. I copied the ad text from his post. Thanks Lance

I am working with a company to build a completely billet aluminum 427 sohc cammer engine. The company doing this is no stranger to billet engines and have motors in drag week that hold the world record and also in the racing industry.. So daily driving a billet engine will be no problem cooling wise or anything else wise that one might be concerned about and the car i'm building it for will be driven daily also. 

 Billet aluminum Fe block with water passages, will have options for any bell housing pattern you want from old small ford to big block to current 2020 ford transmissions. We can do anything from raised cam tunnel  and bigger bore spacing for 600+ inch cammer.  Comes with sleeves also.
 Billet aluminum wet heads 430cfm intake and 290 exhaust
 Billet valve covers
 Billet timing cover
 Billet intake manifold. 2 options. Twin 4bl throttle body efi or carb or 3 twin 71mm throttle bodies with fuel rails for efi.

 This stuff will support large amounts of hp with out the weight of an iron block. Imo will support north of 2500hp with ease.
 So anyone looking to build a gasser or blown alcohol motor this would also be a great platform to start with. Block and heads can also be built as a solid block and heads.
 Both Kurt Neighbor and Jay brown know i'm doing this. Jay is local to me and I will also offer or suggest some of his stuff for building one of these billet cammer motors.

 I'm am pretty positive I will have billet parts this year yet.  I will post pics once some of this stuff starts getting done.

When sleeving all 8 most go smaller not larger, due to stress on the deck. My vote is get another block if this one needs 8 sleeves. Nothing really special about a reverse 105 , and still available.

Spoiler Alert! $3.4 Mil and the fees!

Thanks Doug!

Took my oldest to see it with me today . She is 7, was really surprised that the language wasn't that bad and I didn't have to cover her eyes any. I think she would have been far happier watching frozen2 , but she stuck it out. I told her one day she would think back on it and maybe it would mean something to her. All in all good movie, I liked it almost as much as the time I got to spend with her!
