You got to be kidding. A thousand bucks for a run of the mill small block chevy? They could never stay in business with a price that high. My local yard gets $375 for a complete Vortec 350. Big block chevy 454`s go for $800 to $1000 around here, but a small block? I just sold a complete excellant running factory roller cammed 305 for $400. I know prices vary from state to state but I never heard of inflation being that high.
The only way you`ll get it out of detonation is:
A. Slow the timing way down, which will kill power in the process.
B. Run 105 octane race fuel for around $10 bucks a gallon.
C. Tear it down and replace the pistons with dish tops.
Were only trying to tell you it`ll be a mistake to buy it. IMO, I wouldn`t give him over a $1000 for it and why is because 993 heads are junk, the cam is based on 40 year old technology. Eagle cranks have a poor reputation and they can`t be used out of the box without machine work. The compression ratio is too high for pump gas so that takes out street duty. Your money, your call.
