Realistic horsepower for the street

[RICK LAKE]

Ron61 There is a winner, It's a stroker windsor motor in the 390-427 range. Unless you have an All Aluminum motor, you loose in the weight department. The bottom end of a 351 windsor motor assembly is about 10-15 pound lighter. This makes for a faster revving motor. The FE weight is one of the heaviest bottomends out there. Heads, The best FE head is now into the 420 cfm range with off set pushrods, and rockers. The top windsor head are flowing in the 370 range. In a cobra with a 2,700 weight the torque of the FE may beat the windsor off the line but catch up in the mid range of the power band. Remember that lighter spinning assembly. Top end is just who runs out of HP last. I like my FE motor and like the way it looks in an SC cobra engine bay. I also like 600ft of torque and 550 HP to play with. This was 100 more of both than I had last year. The only thing I will do different with my car is advance the cam timing to kill some of the bottom end. TOO MUCH TORQUE. For racing, windsors are the way to go, they are cheaper to build and have alot more speed parts to work with. Windsor motor are also 40 years old but have stayed in the lime light better than FE. I will leave the BOSS and CLEVELAND motors go for another time. Rick L. Ps the cammer motor is a whole different animal. I am waiting to see how a KCR cammer matches up with a cobra. BRUTAL with an unlimited speed possibility.
