Hello Everyone,
Some of you might recall the thread I made about my Small 16g numbers on E-85. Well I made 361/362 on about 25 psi or as long as the 16g would hold it I should say. The car at the time motor wise had Kelford 272s with dual super tech springs/retainers and the GSC lifters, rest of the motor was a OEM 7-bolt with the balance shift removed with 130k miles and enough supporting mods to run a much larger setup. While on the dyno after getting the car across the street I had some serious lifter tick. Thought nothing of it since we prepped the lifters correctly after doing research here and oil pressure was perfect. The lifter tick went away not long after the car got up to temp and before we started doing pulls. Well got home everything checked out fine and the car felt like a Animal! After coming home from a few shifts at the fire department went for a drive and out of no where the car shuts off before I got to a road that is empty and dead straight for over fifty miles...
After getting the car back to a buddy of mines shop we got the valve cover off and rocker arms went flying everywhere and we found gouges in the head on the exhaust manifold side. Went on to take the head off and found all eight exhaust valves bent and chipped, four intake valves bent. My pistons have beautiful marks in them from making contact with the valves of course. On top of all that we found the keyway sheared off the exhaust cam from locking up so bad. Soooo what did I miss for this to happen????
Did some research on Tuners as I always do and come to find out I feel I jumped the gun and purchased the GSC lifters instead of the 3g revised lifters. I had no idea the GSC lifters were a hair taller and it just so happens to be the only part I didn't go into hours of research before purchasing. Now this is the picture in my mind as to what happened and after speaking with the guys from the machine shop. In no way am I coming after GSC cause I understand there are way to many variables when it comes to something like this. Also I believe the machine shop did nothing wrong, the car wouldn't of lasted IMO on the dyno for three hours and healthy pull after healthy pull in my eyes. Next my tuner is a great dude and I'm much better at fixing the human body and putting out fires then I am at tuning but I know for a fact there was no knock in any logs cause we were sitting next to each other and I would pick his brain on a number of topics.
Any questions comments and concerns are welcome. My profile is up to date for my next set-up so just don't mind the info about my 6 bolt block that is being prepped to get dropped into the car or the +1mm valve work and extra porting. Everything else is the same from before I had the issue. I'm bummed out that's for sure I had the car running for well over five years on the small 16g, good street tune on pump gas, and a stock seven bolt. Buuuuuut as we all know the worst drug in the world is boost and the drive for lower times or a faster car. End rant.
