I was at Englishtown with Scott one time when it blew up. In person. He later put a aftermarket block in it. iirc
Should ask Stephen daurity on here how his faired.

But I would think a small block would be easier to package. I would use a w8 head for the thicker deck. You can make plenty of power.

I would love to see some new hemis at 1000 hp in race cars and live. Don't think there's enough of them yet. There's one local to me that will get raced hard this year and am curious to see how it lives.

No cooling issues with those blocks. I would assume extra meat gives a stiff cylinder wall for better ring seal.

Another question is between the Siamese and non Siamese blocks. Obviously you can bore the Siamese blocks more due to the lack of water jackets but are they any stronger than the other blocks? Obviously if you bore any cylinder too much they will weaken, but if you stay within specs on the non Siamese block will it be weaker. And has there been problems with the Siamese block and cooling issues. I know from personal that it was harder to keep the small block Chevy 400 cool which is also a Siamese block.
I have a 48* siamese R3 @4.185 bore in a street driven car. It runs under 180* in the heat of the summer, in extended driving with 900 N/A horsepower.

Might give brett a shout (W5dart66).... he'll give you an idea of what you're looking at for cylinder heads.
Thanks J_Body. I'll send him a message.
