you also got kasse and steve schimdt. i think these guys are all pro mod drag guys. i think 640 is about all you can get out of a standard big block until you go to the 5 inch bore spacing and than you need all special stuff. i heard that stottler ahd 700 cu in engine in the mystic cintron.
can you say reliability????

08-18-2009 09:48 PMI've seen engines pushing 900 cu in's. The biggest problem I've found, for marine, they are all one off pieces (Big Chief etc.), and every block I've seen in that range have no water passages. Purely aluminum/alcohol drag motors.
There are some big chief stuff in the just over 800 cu in range with cooling passages. That's about the best I've seen. Still one off special parts with giant price tags. I know a couple guys who would be more than happy to help you spend your money on one though if interested.Getting bad advice is unfortunate, taking bad advice is a Serious matter!!

08-19-2009 02:47 PMThe 5" bore blocks are somewhat longer. Probably 3+ inches. IIRC, they're on 5.3" bore centers.
I would love to see someone build an offshore boat with a pair of Packard Merlins.
I saw a boat at an antique boat dealer in Clayton NT last year- looked like a big version of a Magnum 27. It had an Allison v-12 on a gearbox driving a pair of Arneson 6's. Was built by a guy in Michigan I was told.

Hot Rod had a picture of one of the big in Sonny's motors next to a regular big block, maybe 6 months ago, the thing was a monster compared to the Chevy motor.
I'd heard that the big 43 Schiada was built to run V12. Anyone know the whole story?

How about a 1080ci v16? I wonder if they got this idea from Tractor pullers?
