" So what do I do? How do I build a high revving low compression 305 for. Cheap,"
just toss out reliable and powerful,,,,
This is the time to instead of dazzling them with brilliance,its better to baffle them,,
explain piston speed to the last detail,
valve train harmonics,
torsional stress and dynamics in the crank shaft,
after a few minutes of this,give them some math to come up with their best formula,then add in everything you know about oiling a high revving sbc and again let them formulate a formula for you to follow
I doubt it goes that far and they will call off the build,or share info as to the purpose of the engine and reason for the secrets.You use all these questions to put them straight
