If assembled properly and the machine work is done right, it should last a good long time and use no more oil than stock.

Driven my 402 7000 miles last summer, used bit of oil, definatly run little extra compression and use a milder cam, would have rather run something around 230/230 112+2 XER lobes with 11.0 SCR for daily driver, I went with XFI lobe cam, springs are holding up well.

I appreciate the post concerning oil use. It does seem to be a common point with forged motors that many are unwilling to speak about (for whatever reason...).

I never realized that. Why does just forging a motor use more oil ?

several variables come into play, but two of the large ones are: required clearance diffs between piston and bore, and aftermarket rings...

My Thunder Racing forged 346 uses no oil between changes. Some of this no doubt has to do with the LS6 valley pan conversion.

My APE 370 uses about 1/2 quart of oil between changes, ~4k to 5k miles. I am certain that all of this is being sucked in the intake as my FAST appears to be coated inside. I need to get a catchcan on this thing. Basically driving a forged motor as a daily driver is not a problem. Keep a quart of oil in the trunk, just in case, and drive.

I'm sure most oil usage is being sucked throught the PCV system, it's very common. If you built motor is using alot of oil, slap the builder.

agreed onebad there is no reason other than the way it was built that a forged motor should use oil. slap that **** in da head.


note this statement/assumption is made with my experience from past SBC builds I really don't think that the motor being LS based should make a difference.

An engine is an engine, forged doesn't make any difference. And I have about 60,000+ on mine and drive it now over 400 miles a week, yup, 400. Its perfect. Oil burn is high though but it has nothing to do with being a forged engine.
For the first 30,000 miles or so I used about half quart in 3,000 miles.

With modern forged pistons, do you have to set the piston/bore clearances to the point that you get a lot of start up noise, like piston slap?
