2 short blocks, l think one has a lightweight crank 5.2 rods and Wiseco pistons, not sure about that l would have to check to be sure. Been a while since l ran the 2.0 so l honestly don't remember! lf someone is really interested l will take it apart and check. Weiand 4 barrel intake, high rise 2 bbl intake with a holley 2 bbl adapter. Port injection nitrous tubes,Mallory Uni-light distributor, ported/polished head with big valves. Stock head w/ a Ford Motorsport cam, 300/450. Several adjustable cam pulleys, couple of small crank pulleys. And the roller cam set-up, missing one rocker, one spring retainer and 2 lash caps, has springs, big valves. It's an Esslinger set-up, don't know the cam specs but well over .500 lift, maybe closer to .600, still have the ported Esslinger head but the front cam tower is broken, 9500 rpm shifts? Maybe? lol l have a post in classifieds in case l missed something, if there is something in particular you are looking for let me know l might have it,
