Keithc8 Keith unlike you that has a machine shop to use any time if you break a motor 98% of us don't. Yes you can spin a 600 cube motor to 8,700 rpm with the right balance setup, aluminium rods, light pistons, and the list goes on. You know all this and do it for a living. IMO and limited knowledge of stroker motors (any kind) I limit the rpms for these motors. The real limit is the camshaft. 500 rpm past the max HP, is all anyone should be turning. You are just wasteing motor. For a stroker if money was not a problem , the crank would go to Falcon machine for lightening, titanium rods, good set of pistons with gas porting for street use. About 6 holes. Solid roller cam with Dodge lifters, rev kit for the valve train. Control of the valve train is the issue. Any weight removed from the system will help in the RPM's and power levels. High rpm causes both valve float and lifter pumpup. There are fast bled lifters on the market, some work some don't. IMO is a combo of
oil pressure and
oil weight. You can run a hydro lifter valve train and not get float with beehive springs until about 6,400 rpm. If you have very little lash on the plunger, like .015" even if the lifter pumps up the valve still closes and you don't bled off power so fast. Harmonics of the valve springs is the other issue. If you being the BOSS can't guy your guys to help build an EMC motor for the event, GET SOME NEW GUYS!!
. You get a check if you win, funnier things have happened at this contest. How many more motors get sold to shops that win this contest or do very well with a certain brand of motor. BES, Jon Kaase, and some of the others are selling motors from this, even Barry. By the why, Barry has a new baby and is not rich yet, and it's a baby girl. We all know what that means, Love you da-da can you say GOLD CARD VISA???
Only kidding Barry. Keith bottom line is we do want motors that make 700 HP and torque can run on high test gas from a pump, can idle all day without any problems, run 9.0's in the 1/4 mile, and whip anything on the street. The edge between endurance motors and race motors is what we are looking for without power adders. We can save this for another thread.
Rick L. Ps wait till the cammer motors get running.
