Can this # from a Dyno pull be right

I don't post here much but I do a tons of reading and research here and 460 Ford sites. Here are my engine spec, sorry if it to long. i think it should be a bit more. The Dyno result is at the bottom. I'm kinda lost on what to do with it. All suggestion and comments are appreciate.

Will be spraying frogger later

something is wrong 100 low

I'd think unless your tune was way the heck off those dyno numbers don't look right at all. Either the operator is incompetent of the dyno setup is jacked.



IMO the carb size is fine for a street machine but you'd make more hp with something bigger at the strip. That combo is stout. I'd bet it should be closer to 500hp.

Looks a bit rich however, chassis dynos are not a good barometer for actual power with a 4,500 stall speed torque converter; the RWH is most always all over the map. Also, looks like what might be gotten with exhaust manifolds instead of headers.
Use it for a tuning tool and forget about how much the actual numbers say.

Here is an updated graph.

Your torque peak is actually about 305 the 322 was a spike you see when the converter locks on the hit
