Well I can say overall im happy with my build that I got from Mitch and his service. Its been a year and half now the engine has been running strong. I dont daily drive my car but I do beat the hell out of it. Drag strip, track events and lots of street racing. Over all the engine is still in tack. Iv had some leaks but its not a perfect world. I made a post a while back about having lots of blow by that Now Iv found to be a weak pvc system and needed to delete it. Mitch has been great to work with and has taking a little disbeileve from me but stood behind his product. Ash had good things to say about the abuse we put it though when we tuned it and it made good number. 673 with a smother of 5 and with a 2 about 689whp. I would trust him to build for me again if I needed it but this engine is still running strong compression numbers. Ive changed bearings in this engine but thats things you will have to do if you want beat on and it last. They are a wearable part. Ash does it and I do it as well. There are some guys that drag race other engine and only make about 30 passes then redo theres as well. Its life. But all in all I wanted to give a updated review on this engine and its life. So other would now its holding up just fine!
