Hmmm, that question could take a page worth of typing. Let's start with the engine. Yes, I did a 90% rebuild...meaning I reused the cam and lifters...everything else new/re-machined. I stayed with the original babbit bearing surfaces as I was able to get clearances within smallest spec of .002"
The only original parts that I scrapped and went with new is the entire pickup box. The original was simply too beat up and not worth the effort to repair. Oh, and the rear gears and brake system is new. Other than a ton of small parts, everything else that came with the truck were restored.
Hope that answers your question. Of the $20k restoration cost, some costs were not technically necessary for restoration such as:
$1500 was attributable to the A/C
$850 for the brake upgrade/restoration
$550 rear gears
$250 for dual grove harmonic balancer
$750 sound system
$250 seat belts.
