The 540 would be a good motor, you will want to do a cam change to take advantage of the extra cubic inches, May also want to increase the CFM of your induction system.

I'm building a B1 motor right now with a World block 4.490 rough bore block bored to 4.495. I selected a Molnar 4.250 stroke crank and a set of his 7.100 long H beam billet rods with the ARP 2000 bolts. Good luck on findind a good 4.500 bore new wedge block now  , aluminum or iron  If you can't find a new block like you want the Mopar OEM 400 block with after market main caps and studs work well with the same stroke crank or the 4.300 stroke cranks   If you decide to go that way have the blocks sonic tested on the cylinder walls before building

Hey Guys, need some advice. This past weekend I granaded my stock block 500 cu in 440. It appears the webbing let loose around the mains in high gear. Anyways... there is nothing left of that power plant so back to the drawing board. I'm planning another big block stroker but I'm unsure on a few things. First is cu in? If I have the opportunity I'm thinking bigger cubes 540 or 572. I plan on using an aftermarket block if possible. If for some reason I would use a stock block again it will have the good caps and less cubes. The heads that I have are Indy EZ1's flow 345int 245exh (so would these heads even support that big of cubes?) Just looking for some direction. If I bolt my heads on a big cube motor would it be a dudd? You say you will use an after market block,,"if possible". I highly recommend that. AND,,if you find one , see if they have 2. I looked for one and couldn't find one(steel block). I was down all this season after first race with a cracked stock block 493". Just my opinion and findings,,,motor had alittle less than 300 passes on it.
If you like drag racing, support your local track.

Well maybe but it might not matter. A 540 with EZ heads is going to have peak HP at 6200 rpm so you aren't going to be putting a huge amount of stress on the rods. With the 7.100 rod the piston is fairly short so it is probably less than 600 grams. So an aluminum rod might go 500 passes in that type of environment. You just have to call up a few places and ask. They do cost more than steel rods and there isn't any market for used AL rods, but if it keeps you from busting a block they'll pay for themselves. I would think with heads that flow 345 and a 286 @ .050 camshaft it should make peek at least at 7000 as long as it has compression and a 4500 carb

The EZ-1 head is only 275 cc so it has the small CSA and the pushrod pinch. A Big EZ head might carry 540 inches that high. My 514 has 15:1 compression with fully CNC ported EZ heads and it peaks below 7000 rpm. I have .900 lift on the cam, a fully ported intake and a 1250 Dominator.
