Just saw this browsing Youtube. Surely this was already posted and if so please drop a link to the discussion. J.Rob

 
They said that the Dyno test would come later, so I guess we'll have to wait...........
 
499hp and 457 tq not bad , why do my builds always get more tq than hp ? my 426 got 510 ho 560 tq , wtf is wrong ,i'd rather have the numbers reversed

Something in the “air flow management” of the engine can’t keep up with the demand as the rpm goes up.
The torque starts falling of fairly quickly before the rpm gets high enough for the math to work out favorably.
In basic terms........ something(or things) is “too small”.
Heads, cam, intake, carb, headers...... or a combination of them.

In a race car, you can often make improvements to that situation by adding more cam duration.
If you do it in a street car, sometimes the trade off for some extra top end HP, in exchange for poorer street manners isn’t what every body wants.
 
Recently i bought a subscription to Power Nation....and the dyno of that 410 Engine never happened....

Make you wonder if they had problems....or did TF pulled the plug on it...

Using 1.6 rockers is problematic due to the pushrod angle and weight of valve train with fast rate cams when revving over 6000. With this much lift they would need a solid lifter, or factory magnum hydraulic rollers to use 1.6 rockers. Also use beehive springs to lighten valvetrain if using 1.6’s. 1.5’s just seem to work easier For most street engines.
 
I just watched the video and I´m sure they did pull the plug on that motor . Magnum block , no rocker shaft oiling provisions , harland sharp roller rockers and solid pushrods . I wonder how it worked out for them. They should stick to phords and chevvies.
 
Just watched that video with anticipation of the dyno pull... but alas no go . I bet they blew it up or it was a pooch and TF said dont air it .
 
They just have no clue how to build a mopar, and they don't care. When they added power to the 360 budget build they used open chamber eddies with the stock pistons. That engine was probably 8 to 1 at best.
 
My guess is the HP was a lot lower then they expected and TF told them not to put it on tv.
That’s the problem with the huge hype of a non tested head. It the labeled the best SB head without any proof/dyno #’s or time slips to back it up.

I dont think it was a problem with the heads as much as the combo choice.
If TF wanted to use this as a hype for marketing they should have specially prepped the heads and chosen a more aggressive solid roller . 260ish @ .050 on a 108 with .600 lift and 11.1 compression.
 
I watched that today . Looks like they got it figured out. Im not sure why they even aired the first one? Surely they knew the outcome beforehand .

Pretty impressive power for a mild cam and unported heads .

so it made a little less than my 426 stroked 360 with edelcrap heads and a smaller cam , colour me not inmpressed

How did they start this build with a ‘stock’ magnum that had 9.7+ CR and after stroking the stock motor
it had 10.7+ CR. Aren’t all those numbers high? I thought stock magnums had 8.7-9.0 CR

A stroker increases the "swept volume"
