Just wondering, what is the bore spacing on the pro stock hemi head? If someone was to make a tall deck block that would fit that head, would it be a viable option? As i see it, any way you slice it, it will "look" like a chevy engine regardless of what block gets put under the head.

If the pro stock hemi head would serve as a foundation for a big inch mopar engine, lets all get together and have someone start making blocks to fill the void.


I think the guy's name is Goodwin, and they make a billet block for a 5" bore spacing engine, which is what the Mopar pro stock program is built around. Diablo has what I believe is a 655" deal for sled pulling. I want to say it makes around 1350-1400, and the price tag is north of $75,000. He might chime in and correct me, but he will know. Al Alguire also ran 500 CI tamed hemi 99 deal in the 10.5" tire class, he can tell you about that.
That's the point. Al, Boat Racer 572, Steve Gill and I are now working with the predator combos. Boat Racer and Steve Gill, are the only ones I know, and I'm sure there are others although rare, doing it successfully. Indy is useless for information. I have in excess of $1000 just on head gaskets because as I said, Indy is useless with any information/help. If I didn't have help from the other names mentioned here and some I didn't, I might as well be doing this by scratch.
This is where my frustration comes from. Fact, I could have ordered a 665 12 degree GM style race application motor for around $40-45,000 with a dry sump making an easy 1400 + HP. If I needed help, I know at least ten people that have more information and knowledge than Indy, and are ready to help. And if I had my money back, that's what I would do. I've been a Mopar loyalist for over 40 years, but eventually enough is enough. So if or when I decide to sell this stuff and go the easy route, someone will get a sweet deal on this stuff and all the info they want.
