This one happened in the 1987 in Winnellie in the NT, at a very well known High Performance Workshop that just happened to be on the road to Hidden Valley Raceway.
I owned at the time a 1972 HQ Monaro with a heavily worked 350 chev. The motor was putting out 400hp + at rear wheels, with another 200+ Nitrous available.
The motor had been freshly rebuilt due too a failed Magna filter (oil filter), and scoring of bearings.
The business that rebuilt engine went into receivership, so I luckily got car out and back to running condition less some parts they decided too steal.
Car was running rough so took it to said performance workshop for analysis remedy.
Their analysis was the valve springs had lost their tension, and the heads needed to be rebuilt at a cost of about $3600 from memory. The analysis for that cost me $600 car still running like shit remember.
Having just spent over $$$ in parts alone in the rebuild, I opted for a second opinion from a diesel mechanic who mainly repaired forklifts.
The problem was the harmonic had slipped and the car needed to be timed by ear which was normal for that car, but the marks were way out and the said expert used that mark. I think he charged me $100 to get car running properly.
The motor threw a rod a month later due too when the conrods were attached to the pistons the brand on one was upside down, when the motor was pulled down that brand name was around right way (no lubrication or very little).
I then had car shipped too NSW to have brand new engine built worth $$$$, as would only trust people I knew. Picked car up 6 months later and never had engine problems till sold in 1991 for about $1000 more than engine cost.
No I don't own car anymore, it was last seen driving around Wollongong 2005.
Poor old pensioner now on 2003 ST1100P
Just did google search and couldn't seem to find that Performance Centre listed.
I love Carma
