Yeah well I blew the engine last night racing 2 camaro SS's. A silver one had a catback and the red one had I/H/E and a hotcam dyno'ed 359whp. I just hardly beat the silver one and the red one pulled on me, then my engine let go. I am almost positive its the ring lands or maybe some holes in my pistons. I'll do a comp. check soon lol. But whatever, good thing I have engine parts.
