umarjg hi,,i think the engine u r talking about is 4500cc not 3500cc..if its 4500cc then its the same engine used in petrol version of grand cruiser/LS470,,4500cc V8,32v,4cam.
As far as i know toyota is using Inline engines in all of its cars including sports,coupe's,sedan and luxury cars..but they use V engines in jeeps.So this engine can produce alot of torque but wont be able to beat even 1.8 Dohc Vtec...correct me if i am wrong..cheerz
