Notes:

• BPE recommends electric fans that produce 3000 cfm or more, for engines that are 400cid or less. Engines that are over 400cid BPE recommends 4000cfm or more.
• BluePrint Engines 598ci crate engine uses a standard deck height block. So, if you are looking for large cubic inches and replacing an old 396ci BBC, or 454 BBC this engine will bolt right in. Talk about an upgrade!
• The front accessory drive on this engine fits many vehicles, however it is the customer responsibility to accurately measure and confirm fitment. Note this is a low-profile design, but things such as power steering hoses, alternator wiring, and additional fittings/fabrication may be required on some vehicles.
  • Bolt 724hp in place of your Chevy 454 or 396 BBC!
