I would read the BBB reviews. According to one customer's review the engine blew up after 23 laps and CNC left a message nasty message written on the windage tray. The other review is interesting too.

The return policy is 20%, you pay shipping both ways BUT apparently no returns on short blocks, engines or cranks.

Some CNC Motorsports stories and a couple of horror stories with the engines. 2010-2015


Doing a search on Yellow Bullet showed a lot of good review around ~ 2016
Parts buys good, the stuff I found engines pretty good.

Some of the stuff like cylinders didn't appear to be honed....probably 80% good & 20% bad

Time to ask..






Getting burned on an engine purchase is about as much fun as staring down the wrong end of a Magnum. I got burned once by Doug Herbert performance who was local to me. Burning $4500 in cash would have been more fun than dealing with DHP.

Best of luck with the new motors.

My impression & opinion based on a brief Internet search is CNC might be OK for simple parts.

No way I would buy a short block or engine or crank after what I read.
If you are local to CNC then you might be OK.
A lot of businesses do better taking care locally than someone a thousand miles or more away.

I the sort of person that's much happier to pay Lingenfelter Performance or Thompson Motorsports or Texas Speed or Reher - Morrison or Bischoff Engine Service or other good LS1TECH vendor a little more and not worry. All of the ones named have a good reputation.

Your right. It's not an LS7 4.125 bore w/4 inch stroke.

​​​​​​I guess my "new daily driver" an 02 Z28 will just have to keep chugging along with the original 242,000 mile LS1 for a while longer...

The oil consumption is about what my ls1 was not much. I have 9000 miles on it. I wouldn't worry about the 4.100 stroke they built plenty of them.
