My 392 dyno numbers

Decided to go with a buddy since he was putting his boss 302 on the dyno so I decided to see what mine put down . Run was done on a dyno jet 3 runs back to back no fans on the car but hood was open graphs are sae and std . Red run was 5th green run was 6th 1-1 surprised to see 6th make less . Numbers are what they are but I’m very happy with the curve 437/444 SAE and 449/454 STD ..

Dynos....blah.
Good to see the strong curves.
Last time I ran my car it made 434.7 or so....but i'm confident you are up a good 40+ rwhp over my stock setup. Trap speed tells that truth.

Exactly can’t wait to try the new setup at the track on the 22nd . Should be couple more mph in it if all goes well

I've seen like 480whp on E85 FBO.

Decent numbers for sure. Not sure you will be able to hit 500rwhp with cam, which would be awesome.

I dont think many people have really tried to cam a 6.4 for max effort.
Hands down, the 6.4 head is amazing, probably the best flowing head from an OEM on the market currently. Taking advantage of all the available airflow these heads offer will yield strong numbers, no doubt.

Buddy already hit 550 wheel with his 392 but that’s with aftermarket heads . I don’t get caught up with the numbers what it runs at the track is all I care about .

Yeah, searching "6.4 Cam" just comes up with people putting a 6.4 cam into a 5.7.

I'd love to have some old school thumpies.

is anyone new cutting cams for 392 or are they regrinds?

N8ce flat curves for sure. What I've read about the intake you have is the oeak numbers arent much of an improvement but the power under the curve improves across the rpm range. Meaning your rpm to rpm power is improved even though peak is not increased. From what I have seen, this indicates that the intake makes more useable power, but there is something else limiting the increase. It sounds like a cam would indeed net you some serious increase provided the heads are flowing.

Nice curve. These cars are not bad. I just bought a 1320 and I love it.
That said, I will never give up my gt500. These cars could really use at least 500 wheel to satisfy the itch that one inevitably gets after purchase.
Just need a cam that adds 75 wheel and still averages 19mpg. Like asking for a 427 in the new Shelby instead of the 5.2.

Sounds like a 75 shot would do it!

Down on power or not, I bet that 1320 would walk a stock 5.4 GT500 in a straight up drag race
Short of excellent stick shift abilities, it might even take it in its current form, they run good!

Isn't because you’ve taken a lot of weight out of your car compared to the others with more hp?

These guys make a lot of custom gen 3 Hemi cams. I've dealt with them before and they were always helpful & professional.
HEMI Camshafts

Look like all stock regrinds.

Even if he put the weight back, its a very strong running 392.

I know, I know, stock coyotes all trap 121
