I guess I will have to wait.
How much of a lead time for your block?
Are they cast in the USA, or over seas?
If you are referring to the BMP aluminum block, cast in the USA although I never asked, I'm pretty sure about that. If you call Bill Mitchell Products and ask, post the answer please.
I know that with all of the problems reported by people I trust explicitly, like IQ52 Jim Laroy, and others, who have reported the massive amount of "corrective machining" required for the Indy block, and the horror stories about finished blocks and engines from Indy, and I don't see how Bulldog is going to make it, and I take no pleasure in saying that, I hope they are successful, but between being late on delivery, bad blocks from a "change in ownership" at the foundry, and not returning the emails from late January from a customer who paid in full, especially after promising to do so, there's no way I would give them a look, much less my money.
The place I'm dealing with for the BMP block AND the build is a Godsend to me. Jim Laroy has engines to finish and hasn't and won't take any more business as he wants to retire, so it was really hard for someone like me to have confidence in finding a builder. I'm sure there are others out there, but I have had all positive experiences with the shop I have my BMP block ordered through, I've bought stuff from them in the interim, and they LOVE Mopar people and have a depth of experience with Mopar like few do, and in my opinion, that matter and makes a difference in the ultimate performance of a Mopar build because of the unique properties of Mopar engine design, like the larger diameter lifters allowing for a more aggressive cam profile. If a builder doesn't know that and design a cam and valvetrain around that, I believe they leave power on the table.
