Rebuttal of the "Less Stroke/Cubes=Rev Faster" Argument

[RICK LAKE]

Rodknock Jay Brown is one for the front runners for helping the FE motor return to being a challenger for top motor ever built. There is a BIG different between a SOHC HEAD Motor and a TP,MR,HR, motor. Valve train alone with worth about 1000-1,500 rpms more than a pushrod motor. I hate when Jay does this apples to oranges stuff.
IMO the only reason a big bore short stroke revs up faster is WEIGHT. Also the fact of the Valves have a little more room around them for intake and exhaust flow. This motor will make a little more power.
If you want high rpm's and high HP you go with a BB/SS motor. If you are looking for a large torque band, a square motor or longer stroker works better. Advancing or retarding the camshaft will also move around the power bands.
Any way you can lighten the rotating assembly is going to give you a quicker revving motor. Any way you can lighten the valve train the motor is going to rev up quicker.
There are a couple of guys out here that are running small bore long stroke motors. They make large power and rev to 7,000 rpms with any problems.
If money was no issue and you wanted a 527 motor to turn 8,000 rpms, lighten up the crank shaft, aluminum rods or titanium ones, run even honda ones if needed. Rifle drill the crank and cut down the weights on it. Balancing will be very critical. Here is the best of both worlds. SB weight of rotating assembly in a BB motor. Lighten up the valve train, Small stem valves, titanium on the intake side, Coated ones on the exhaust. Lighten up rocker arms and pushrods. Go to a larger pushrod diameter, thin wall and have smaller ends. Life on this motor is about 75-100 hours before issues.
Build a torque motor either square or under bore size. make the drive train setup for this power band and you have a motor with a little less power and will last 3 times longer and run easier overall.
My cobra weight is 2705 with 1/2 tank of gas. The 500+ ft of torque is great. Having a 6,200 max rpm also saves the motor in the long run. I can either lightup the 17" 335 tires at will or roll on the throttle and have great accelleration. Suspension also has alot to do with ANY cobra and how it handles both road and power train wise.
I'm building a 498 motor that is under squared, another 80+ft of torque more and about 65 hp over the 482 I have in the car now. Adjustment will need to be redone again with driving and suspension to make is all work togeather. Rick l.
