Re: FS GM Fastburn Heads
Yes they are brand new never been installed worked on ground on etc. In the pics I sent the reason for the various views so each side can be seen on both of them.
Did I get offers? What does that have to do with anything? The answer is yes but in the end thier wife girlfriend whoever did not give them the ok to buy and yes it was at the asking price that was not a problem. I bought them for my C4 Corvette with the plan of shooting for around 425 at the crank then got thinking I really do not have the energy and ambition to update the Dana 36 transmission converter etc.. Don't have a real need to sell them money wise but need them less than I did when I bought them.
These are going for around 1450 to 1500 a pair for exactly what I am asking 1000.00 both never been used.
Let me know if you are interested.
