    Don't ever underestimate a 292 with a couple little mods and it being a stump puller. I'd have one. My only issue with them, is aftermarket mods are expensive. Price a 4bbl intake and headers for a 292. Not cheap, and I haven't even looked in a long time.

    This.^^^

    Stroke a 454 to 496. 781 heads. Deck the hell out of the block so the piston isn't sitting down in the hole.
    Go high compression, like minimum 10.1, and run propane with two mixers.

    You'd need some dome with 781s they are 119cc+ chambers if I remember correctly. I'm running 96cc and a pretty good dome and a .021 metal head gasket to get 10.5:1 in my wee big block.

    Absolutely. I have Probe forged pistons that came with the stroker kit.
    They say they are 10.1 but of course that is relative to the heads used and how the block is decked. Lots of power and efficiency left on the table when the piston tops out below the deck.
    I'll have to assemble the block with crank and two caps, and one rod and piston (without rings) to determine how much more can be milled off.
    There are the kinds of details that make a difference imo. But it's a lot of extra work and if you don't like this... well...
    I must have an easy 40 hrs in porting my heads.
    But I live for this.
