Hold on, lets stop the hp arms race, we know where that will end I believe these are targeted at the high end bracket engines, say a low 7 second rail for weekend big dollar brackets. 1000hp . I have never built a Mopar at that power level but have built 590" 9.800 deck, 636" 10.2 deck Chevys and someday will finish assembly on a 665" 10.72 deck Chevy. A 700+ " Chevy requires a 11.1 deck block. I don't think that would be cost effective at 1000hp. Just my 2 cents.
You might be surprised at how much stroke you can stuff in a BBM soon.....A typical modern 235-242" 4 link car typically equipped these days are 1900-2000 is pounds plus or monus depending on the size of driver and equipment. 1000hp in a 2000lb car will get you 7.30's in an 1800lb car now you are running 7.0's but that would be a light 4 link car these days. But heavy for a non suspended car. Not many people run hardtails bracket racing anymore. But there are some. A good 565 will easily make 1000hp, we did one that runs 181 at 9.05 in vegas in a 2040lb American. Will run low 20's high teens in Vegas. Basically what out Mopar powered Racetech runs.
As for 700" plus as I said if one was so inclined. The point is you can buy a BBC from 9.0 deck to 11.2 if you were so inclined. Then you get into the 5",5.2" and 5.3" BS stuff which are purpose built race engines. A block from Donovan, with heads studs, will run you basically the cost of an Indy block. So I dont think including it in the discussion is out of line at all. Just my
