How much is a NOS 427 tunnel wedge manifold with NOS linkage, NOS carbs and NOS fuel log worth? If you said $3500 you would be low.. That gets you the induction system and you aren't even into the money parts. Machine work, which believe it or not is more extensive on a NOS block than a seasoned block, $4k plus the block which was $5.5k plus the crank that was $1k.. sonic mapping, Eagle rods, Custom pistons, .005 over, $700
oil pan $400 NOS valve covers, $150
oil pump... You get the idea.. NOS (upgraded) C5AE heads $4000, valves, springs rockers, $1500.. Assembly and fitting, misc. costs, NOS water pump, alternator, New Mcloud clutch, 3 hours of run time and a half a dozen dyno runs, shipping from Hastings, Nebraska..
I'm not saying it is a good investment. Or maybe it is.. I'm just saying I know a guy.. (many of you do as well..) You need to pay to play. You want to play NOS, I'm just saying it can be done.. It costs.. Thats all.
