I am going to shorten the sob story to this - went on deployment, wife went buckwild with car and another dude for 6 months, came back, got car back found out daily driver got totalled and she spent the money rather recklessy, que wrathful vengeance and divorce.
Anyhow, the motor was a brand spanking new 454 that I had just done the intitial break in to and drove all of 8 miles. Heads needed to be re-torqued and it still had some crappy springs.
Did some real quick maintenance on it since I had a fat load of paperwork to do at work, didn't see anything too out of the ordinary outside of a really puffy oil filter. Now, being the relatively huge idiot I am (in spurts), I was out of 30mpg and a wife, so I drove it to work while I was waiting for a car loan to come through, about 3 days and 30 miles total. Well, one day I wasn't paying attention and left it in second while getting on the freeway (new trans, forgot that the shift placement dial is off by 1). Probably hit about 4krpm when all the sudden I started getting huge valve float. Backed off and threw it in drive, started going uphill towards the gate, gave it a bit of a throttle and then starting get crazy exhaust backfire. Let off the gas completely and the car idled out while I effectively established a blocking pattern on the road. Attempted to restart the car, started, fired, gave a tad of gas and started backfiring out the exhaust again. At this point I gave up on roadway diagnostics and had it towed to the shop. Went to the shop later that day and drained the oil to find it full of super shweet metal shavings.
My experience with motors is small block top ends, pretty much intake and up with limited carb experience as well (installation, removal, cleaning and rudimentary tuning) so I am in the process of just sending the whole damn motor back to the builders (out of warranty ). I just wanted to gauge you guys to see what you may have thought the issues may be.
I'm sure ya'll which just punch me in the face for driving it...I know I made some pretty crappy decisions starting with marrying a crazy, raging woman.
