How long can a stroker motor last ? Iam talking specifically about a 422 CID motor.
If we say that a totally stock LS1 with some occasional street/track racing can go to about 80k miles before a re-build is needed (assuming regular maintenance is being performed), would it be true to say that a 422 motor can go 40k miles ?
This is also assuming that no NOS/boost applications will be applied to the motor.
How would the extra bore/stroke affect the engine longivity ?
Iam asking this because Iam seriously planning on getting such motor within months & I want to make sure that Iam making the right decision since Iam planning to keep my car for atleast another 2 years.
Thank you in advance

Re: How long can a stroker motor last ? It all depends on how you maintain the motor and how much you beat on it. Drive it like a "normal" car (yeah, riiiight) and it will last 100K like any other motor. Beat on it daily and race it often, and the rings will wear and you are probably looking at 50K before needing a re-ring job.
BTW, most reputable engine builders offer warrantees on those larger motors. For example, MTI offers a 2-year, 24K mile warranty on their 422ci setups, and encourage you to beat on them.

Re: How long can a stroker motor last ? Thanks Tony. I know you have one of the very first big cubes motors. Colonel's 422 has been running for a while too.
Iam not really planning on beating on the motor. I might do WOT only once per drive, and my car is not a daily driver either.
MTI seems to be doing some real good work

Re: How long can a stroker motor last ? I would think that a LS1 will go more like 200,00 miles with normal driving.
I have a 422ci motor, and would like to get 80K out of it before I pull it to make it bigger. I was just talking to Nick @ ARE today, and mentioning how I have a couple thousand miles on it now... Uses no coolant and NO oil. <img src="gr_stretch.gif" border="0">

Re: How long can a stroker motor last ? boy do i really disagree with only being able to get 80K on a stock LS1. now ofcourse it all depends on HOW you drive it. if you ONLY run quarter miles at a time, them ofcourse you will not get too many miles! but i would think you could EASYILY get 150K or more out of a car that is not strictly for racing.
now anyone can take a stock motor and break it in a weekend if they really wanted. if the motor is put together correctly, then you will get plenty of worry free miles. beating it and running it past its intended load (raising the rev limiter) is another story.

Also what's your piston and ring setup? I thought it was pretty much a given with forged pistons 1 qt /3000 miles was normal oil usage. thanks

Re: How long can a stroker motor last ? Dean, some of the first resleeved LS1 blocks were using coolant because it was leaking past the sleeves. My motor was one of them, but it was fixed when I did the cam/rodbolt/head updates a few months back. The blocks were originally done by a contracted machine shop, but now are done in-house using a much better method.
2200 miles and no coolant usage, and about 1 quart of oil so far due to break-in most likely. And yes, forged pistons tend to use more oil than hypereutectics. This is because they are manufactured to less diameter tolerances and expand more than hyper pistons. Expect about a quart every 3K miles or so. Probably more if you like beating on it all the time or run it hard before it gets hot.

Re: How long can a stroker motor last ? 1. I thought PSJ's was a 418CI and...
2. With only 2,000 miles on it , how much oil usage testing could he have? Does it really not use any oil? If it doesn't, GREAT! I would just like to know.

Re: How long can a stroker motor last ? The old 422 I had installed about 14 months ago did use some coolant. This caused it to foul O2 sensors. That block has since been replaced with one of MTI's in-house prepped blocks. Result? ZERO coolant loss. <img src="gr_stretch.gif" border="0"> I don't think that problem is an issue anymore.
Re: How long can a stroker motor last ? Ron, I didn't calculate the displacement correctly, and was not able to reach Nick when I did my sig. It is a 4.060 bore x 4.075 crank (offset ground 4.000 Lunati crank).
I forget what the mileage was on the car when I picked it up.
I have changed the oil twice.
Maybe a wee bit of consumption, like 1/4 of a quart.
Car has not used coolant. My old 346ci motor made by somebody else used coolant due to issues.
In good weather it has not been ususual for me to drive 200 miles in a weekend.
