Ben I've been working as often as you, no money.
Of course it's stock heads, original headgaskets, one platinum Bosch plug end went through a valve too, original pistons, crank.....
Rope main seal with 148K on it too.
Only 156K miles on da motor, new timing chain and valve springs however.
If you can buy a car with a BUICK built motor you are at a great advantage over many other cars, rather have that than a rust free one.
Simple combo, extender extreme for Siemens 55's, ALKY. DIY and SMC, double ball bearing Innovative P trim GT70 from Cottons, a V4 with bent up scoop and leaves in it, BSTC boost control, 4" Mark H. chrome air inlet and K+N under the bumper, Translator+ and 3.5" LS1 Maf., Kenne Bell second GSS242 Walbro pump running stage3 for alky. at 23 psi. turn on and a Jesse Jackson ported throttle body and a power plate, pedophile downpipe and hollow cat with KenneBell dual 2.5" exhaust, and Postons headers recently welded, ATR crossover pipe.
12 to 1 A/F flat accross the board.
Bunch of diagnostic stuff I never use too.
Got 380 out of the old TA62 turbo at one less pound of boost.
