Not sure but with that carb and manifold and exhaust 14.0-14.3 around 98-99 mph Need better exhaust and the AFB got to go With a little tuning you could well see 12s




You were closest- Car ran a best of 14.2 at 94 mph.

Car barks the 10 x 26 slicks hard on launch, I had to lower the tire pressure to 9 psi to get some hook!

My power wheel states 249 whp based on ET, 235 based on mph (car with me in it is 3610 on the scales.)

Not shabby, my buddy states a stock Dakota R/T 2WD will rap out 195 to the wheels, so I'm 50 hp over a stock 5.9 motor.

The cam makes to much low end power and the exhaust manifolds are just killing any top end, as I expected.

Tried jacking the timing about, it liked what I had it set at from the gitgo, 36 degrees total. Tried 34 and 38 and the mph fell off both times.

Car really didn't care if it had the stock air cleaner or an open unit. If I had more time I'd run the 750 but there was no more passes to be made before heading for home.

That car needs a serious diet, my 75 BB duster weighed less then 3000 lbs., it had all steel & glass, also had iron heads, those bumbers/brases are a solid 165 lbs. that can be taken off.

Don't know what your Alt. is there but that 360 magnum is sleeping IMO & can do "much" better. Mine likes 30-32* total.

I'm curious, what were you shifting at? Mine is somehow limited to 5100, i can't amagin anything being the limiting factor other then the cam in mine, its already in the mid. 12s.
