615 cubic inch 1100 HP pontiac big chief!

This is a fairly standard rendition (as such things go) of an all-aftermarket big block Chevy. For the claimed hp level and the displacement, it seems a little under-carbed and over-cammed, though of course that depends largely on what portion of the claimed hp is supported by the nitrous, vs. what portion is all-motor. At this level, typically the block would be aluminum, and often they get a dry sump, or at least one of those fancy billet oil pumps.

 

Would be an interesting swap in a Z - with suitable chassis and suspension mods, of course. :-)

Stock bigblock chevys are Supposed to max out at a bore that would set you to around 614, aftermarket blocks that are bigger built can support upto a 472.

 

My manager is gonna build a 614 alcohal motor for there mud truck, should be pretty stout, his last motor was a 383 alky with between 800-900hp, taking it to the dyno then selling it.
