thanks Many say you cannot bore one this much but i am proving this theory wrong..Block has been .125 over since 1997..i have had it 3 yrs its been refreshen and i run the piss out of it..gas and alcohol.. i have also heard that the (512) casting is a little more beefy than some other castings...i don't know about that...some of the guru's on here can enlighten on this subject....check your castings on that motor before paying him.. so yes..the stock 454 block can be a 496ci no problem..and bigger.

We ran our 505 (4.350 x 4.25 stroke) at 7500 RPM for 8 years with the blower on top.
This was with a Cola crank and Oliver rods (3.5 Arp Pro Series Bolts) If you had a tall deck, I have a set of 13:1 JE pistons (7 of them) for a good price. |

The quick way to ID the tall deck is look at the water pump mounting holes in the front of the block. You can see the extra .400" sticking up right there. 8) JB

I turn mine to 6800 every pass.Cam/valvetrain rated to 7500.Have run a few times shifting at 7500,just keeps pulling!!Machinist who setup up the motor said it was good for more.Mine is 2 bolt block with ARP studs and stock caps.You'd be amazed what a prpoerly balanced/clearanced/assembled motor will survive reliably.I'd be more concerned with valvetrain parts( good caps and pushrods) more than anything else
