like the title say 700 from a 410. I'm looking for the recipe. What heads,intake,compression and cam? This will probably be molnar crank/rods and whatever forged piston.
Pretty wide variety of combinations will make 700 horsepower with a 200 shot.
Living long is where you work toward.
Steel crank n rods, h beam, forged light weight rotating assembly ..at the minimum studs..but caps sound like a good idea. I don't believe girdles on sbm help much. It will have to rpm, so heads and exh better be up for it.
