[QUOTE="CV355, post: 15685359, member: 181885"] Numbers seem high, but not unrealistically so. It's possible that the dyno is "number friendly." A good 4.6l 2v is around 210-230 rwhp stock. Full "bolt-on" N/A cars are getting around 250-270rwhp. When I had a KB 2.1 at 9psi, my 4.6 made 330rwhp and then 370rwhp with cams. Granted, a centrifugal is usually going to make a higher peak hp number than a twin-screw at the same psi, but I do not see 450rwhp being feasible without serious head porting or 12-14psi. Numbers aside, the price isn't bad for what the car has in it, as long as everything appears to be in good shape. Just my $0.02. [/QUOTE]
