I brought Greg a 5.3 ls with over 200k an lower oil pressure.
Had him do full over hall on the motor
Now it makes 50 lbs oil pressure at idle an
Looks better then new
It lives in a 1995 Nissan 240sx. So you know it has a hard life  4000 miles later Motor still running strong 0 issues
I can't emphasize enough on when I say hard life it see nothing but redline  rev limiter An high heat because I moved back to TX.
10 out of 10 would have him build my next motor.

Best engine block and head work done hands down. Had Craig work on my Jeep 4.0 motor. Bored .030 over. Install cam bearings. Clean and magnaflux the block. The head needed new springs and valve work done also. I cudnt be happier with the finished project. This was a mud jeep and was really beaten on. Years of cooked on mud and grease. Inside of the block and head was so black and carboned up it look like this thing ran on coal. But its gone now, fresh and clean. I almost was thinking it wasnt the same block i got back becuase it looked so brand new. He even takes the extra time to check your bearing clearances on the crank bearings, making sure they are in spec before getting the block back to you. Most shops do not do that. This is my 1st engine build and he took the time to explain build tips and start up procedures. I would definitely repeat business with him and recommend him to others. Really great work! Craig really knows what hes doing. If anyone is interested and wants to before and after videos of his work i have a you tube channel on the build called "While Ur In There".... Shameless plug, but the videos i have will really show you the quality work he has done. Im very confident that this Ol 4.0 will get another 200,000 miles easily on it without internal issues. Thank you Craig and RPM Engine fir the great work. One very happy customer here
