Well I kinda agree especially on an endurance application like mine. The hot ticket would be big bore/ short stroke but the only block that comes close is an overbored 340 unless you have a race block.
I am not a big fan of these 408+ engines especially with heads that can't supply enough air. I would want at least 330+ cfm on my race motor if I went that big.
My son used to maintain a friends large muscle car collection. I drove one of the 408/4speed Darts in the collection... Not impressed. Just my opinion.
