Inliners International Forums General Discussion Engines 261 Engine - Oil Pressure Pump Performance

I've been talking with folks about increasing the oil pressure provided by a 261 engine oil pump.

The discussion started with comments about V-8 engine oil pump pressure being increased by shimming (increasing pressure) the spring to the oil pump pressure relief piston so the amount of pressure going to the block would be increased.

The system in my 261 engine's is the same so why not install a 1/8" shim to improve the oil pressure in the system?

Comments?

Thanks,

Ted
