Tuned friend's ghetto-rescue EX w/ebay kit (10.9psi with 57trim, z6), he pulled some 14.1's with steelies, sold it a week later, was blown the next day. Apparently he didn't realize cranking the boost another 10psi with a stock MAP will lean it out like no tomorrow. And throw a rod.
My HS never had automotive, just a half-ass metal/wood shop class that was a complete zoo. Didn't stop me from rebuilding my 67 bird's sb 350 all by my self, before intreweb had good info on it. Graduation day I did 2 mins of donuts & brake stands in the parking lot. :yes:
Too bad you didn't listen to JD, look at the car, offer 75% refund, fix/flip it and have even more money.
