Streetable 450hp 390
FordRacer,
SF Firedog is right on the money!! Only thing I would change is the possibility of running either a hydraulic roller or mild solid roller cam!!!
With a CJ crank-422 ci, .060 over, Edelbrock heads-mild porting, 10.5 to 1 compression, Performer RPM intake-port matched, 800 cfm carb, and a hyd roller cam at 236 duration at .050, you will make about 509 hp at 5500 rpm. 553 ft/lbs of torque at 3500 rpm, and 516 ft/lbs of torque at 2000 rpm.
The age of flat tappet cams is over. There is no reason not to take advantage of todays technology in camshaft design!!!!
With the aluminum heads and 10.5 to 1 compression, you can run pump gas with about 38 degrees total advance. And as you can see there is gobbs of low end torque with this set-up. The engine will idle around 900 rpm and definetly be very streetable in a Cobra!!
Call me if you have any more questions!!!
Tom.
