Default dyno seems low

I recently bought a NBM 01 SS it has a RPM4 cam 232-236 595/601, patriot stage 2 heads, ported throttle body, underdrive pulley, long tube headers, off road Y pipe, K&N filter. On the last dyno tune, it dynoed 410 hp, 380 torque at RPM in Lewisville, Texas. I think that is low as i have seen cam only cars put down that. Just wanted an opinion.

mustang dyno numbers are usually lower than wat dynojet's read.

I would hope you hit atleast 410 with a cam that size.

I was looking at the wires today they look new. I will check the plugs when it dries up outside, the motor ticks a little and i have read on here were someone said it could be the plugs.You cannot buy 93 oct here 91 is the highest.

That would explain a lot if it actually has stock heads.

the guy i bought the car from got it with the mods on it. the only thing he did was put wheels and a panhard bar, which took him ALL day to put on. the heads have been replaced i have a receipt from RPM that showed them putting a set on.
