$700.00 is a very fair offer IMO .
I know of a guy here in NJ that just bought a 1954 NOS Chev 235 fitted block for $500.00
It was offered to me & I turned it down because of the date code did not work for me .
That's a heck of a long ride from Alberta to below Nashville !
The guy who thinks it's worth $5K is delusional !
It still needs Rods , Crank & Cam & lifters , Oil Pan ,Oil Pump, etc . etc. etc. .
That's a lot of part collecting !
