Dart Pro 1 heads, Scat crank, Scat I beam rods, Forged pistons unknown brand. Looks like a solid build with good parts. Cam specs Hyd roller 231 235 duration .544 .565 lift 112 LSA That will make 460 HP with a dual plane intake like the Stealth, RPM or Air Gap and a 750 carb. Anytime you buy a crate engine you are taking a chance. Does not matter if its Ford Strokers, DSS, CHP, Blueprint or ATK. They all have issues at sometime or another. I have never seen a local builder put any warranty on a performance build but if something does go wrong you can at least yell at them in person and I have done it.
