What kind of oil pressure does a big block Chevy have?

What kind of oil pressure does a big block Chevy have?

This may sound simple, but we’ve seen this happen many times. In a situation that recently occurred at Westech Performance, dyno operator Steve Brule’ witnessed a significant dip in oil pressure above 5,000 rpm on a 600 hp 468ci big-block Chevy.

Which is better high pressure or high volume oil pump?

When this occurs, many enthusiasts believe adding a high-volume pump will help. “A high-volume pump will increase the flow to the engine, which will provide an increase in pressure. The amount of the improvement depends on the amount of wear in the engine or the size of the leak,” states Osterhaus. But, you still have the leak or worn condition.

Is it possible to have very high oil pressure?

It is possible to have very-high oil pressure with very-little oil flow. Just a side note, viscosity is also resistance to flow, so the viscosity of the oil itself obviously plays a role in oil pressure.” As the engine spins, the meshed gears within the oil pump also spin, creating flow.

Where are the plugs on a BBC oil pressure sender?

There’s 5 plug’s that are in line with the main bearing cap’s on the driver’s side of the block that can be used. There’s also 1 on the front of the block on the driver’s side that’s the same galley as the rest. You can use any of those to install the sender.

What kind of oil does a BBC 468 use?

Well it seems as thou my 468 bbc will not hold oil pressure for very long before it slowly starts to fall. It will start at 80 then go down to 20 once the car is warmed up. I have replaced the oil pump with a high volume pump (moroso) running 50w oil.

Is it normal for BBC oil pressure to drop?

It’s normal. too much clearance in the rods and mains will let the pressure drop.. 20 is fine at an idle and 45 is ok at 3k .. id bet its all bearing clearance. I had a 283 i built once that had 40 lbs running at about 3k and 5 at an idle never could kill it it ran forever..

What should I do if my oil pressure is low?

Engines run on a percentage of leak in the oil system. The greater the % of leak the lower the total oil press at operating temp. Check clearances,make sure all internal oil gallie plugs are in place and last check the oil temp>>>>. sounds like the engine was built with the rod and main bearings at the loose end of the clearance scale.

What causes too much clearance in the oil system?

Too much clearance . Engines run on a percentage of leak in the oil system. The greater the % of leak the lower the total oil press at operating temp. Check clearances,make sure all internal oil gallie plugs are in place and last check the oil temp>>>>.
