FRPP Scj pistons ?

Is there an off the shelf piston for the stock strock 460 ? I dont think my 429 domes will work with out major mods. The domes arent made for that chamber in the new heads.
SOO...Whats the least expensive route to take ? mod the 429 pistons and run 429 ? or ?
The pnly thing I see are stroker pistons for the FRPP SCJ's. Hmm.

Diamond will make anything you want. Not much more for a custom set of pistons from them.

Diamond, but they cost just as much for a set to fit that 4.3 crank you have..............add a set of rods.........no lookin' back...................

Run ANY flat top piston and have intake valve notches machined into them if you have a big camshaft.

Well three options looks like any of them are going to require a roll cage in the car... I'm looking foward to this. Thanks for the help
