I should have a copy of the dyno sheet to snap a pic of. Also have cam information, let me dig that up. Should be similar to the 741 that was on backorder forever.

.030 over would make it a 489", .060 from std 454 bore would be 496. Just FYI, still within safe limits of a mkIV block.

$6500 FIRM - no exhaust but otherwise complete. Keep in mind this is a fresh build from one of the best shops out there with dyno time only. Like to keep it but just dont have a use right now.

Also I have no problem swapping out the valve covers for all the non-sunsation owners out there.

How much do you want for the Sunsation Valve Cover?

Dont really want to split this package up as its fresh and dyno tuned. What are you looking for in a short block? I have a short block going to Champion soon that was going to be the base for a blower build but may be interested in selling as I have all winter to build new power.
