That was pictured a few posts down.
504 ci. 10.75 to 1
CNC ported heads and hand ported intake.
The intake ports are as far over as the pushrod tubes will allow
and are a bit smaller than the heads.
The cam is 262/266 @.050 .691" .697" lift with 1.8 rockers on a 112 lobe center installed on a 107 intake centerline.
It is a mechanical flat tappet with Schubeck composite lifters.
Idles at 750 rpm with 11 to 12 inches of vacuum.
545 hp @5600 at the rear wheels with the crappy Superformance 1-7/8 headers and restrictive side pipes.
603 ft lbs of torque at 4700 rpm...at the rear wheels....
Drives like a stocker... pulls like a freight train...
The power and torque dips about 30 to 35 hp right about 4800 and picks back up at 5200.
It is reversion caused by the really short intake ports. I am trying to tune that out with the laptop but I wish I could put a longer stack on this size engine.
My calculations show it would really like a 12 to 13" stack... Not very practical or attrative on a Cobra...
Also the wide lobe centers help with drivability but ultimately hurts a tiny bit on the top of the torque and horsepower levels... not enough to really matter though...
