    over the weekend while at a car show, a guy parked next to me in a very healthy sounding 67 camaro. Once he got done wiping his car down, I proceded to ask him what he had done to his 454? He went on to say it really wasn't a 454 but a 548 with 13:1 compression that he drove about 60 miles one way he claimed this was out of a production 454 block. I really don't know a whole lot about big blocks but it seems like a lot of cubes to stretch out of a production block. I did however see a kit for a 548ci in the Doug Herbert book?

    Most 454 blocks will max out at 496. The after market World Merlin III blocks can be punched pass 600ci

    It's fairly eassy to get 520+ cubes from a stock production 454 block...

    535+ is possible..

    I am looking to build a 496, i have priced out an eagle rotating kit with SRP pistons. Will be 10.69-1 compression with my 110 CC heads. .060 over 454, with a 4.25 stroke crank and a 6.385 rod.

    A production "TALL DECK" block, is the key word. A "TRUCK" block. Not a pick up truck block. I think the old school was a 572 cid. With all the new cranks, who knows what the hell. A 510cid was a "SHORT DECK" with a stroker crank with some grinding to the block to clear the crank...

    Is that just stroke increase or bore too? I recently had 2 454s sonic checked and neither one could safely go .100 over

    I figure this is about the max. on a stock, early '70's/'80's P/U truck standard deck height, 454 block.

    4.350" b x 4.375" s = 520". Should drop right in, imho..

    AND yes, a tall deck block can go upwards to 550"+!! with the same .100" or .125" overbore!!
