Got any moore info on your motor. What bore etc. I am running 750 HP on 5lbs boost bore is 30 over. I'm sure i would see at least 800hp with 7lbs boost. If you have any pics please post.

You said your shortblock is stock? How are your hypereutectic pistons holding up?

Re: 496 CNC ed heads by Tyler Crocket
 

I didn't see a price for the port/polish and valve work on their website? Could you PM how much you paid for just the headwork? Thansk!

Re: 496 CNC ed heads by Tyler Crocket
 

Me too on the CNC work, Thanks

Curious also about your short block. Could you maybe recap your setup i.e. crank, rods and pistons.
