I just don't see why you wouldn't have gone for a stage or TA block if you put that much money time and effort into the car.
Think of it like this... By the time you sold a good 109 block core and include the cost of the girdle and machine work it probably would have only cost 2500$ more to have put in a BRAND NEW TA aluminum block and run a 14 bolt head. That's not that much more if you have put 80 grand into the car.
Good 109 block would bring 400$
RJC Girdle cost 400$
All the machine work and girdle install would run at least 600-700$
I'd say this car could/will eventually bring 30-32k, but it would have flown off the shelf for 35-40k if it had a TA block and 14 bolt head.
It's hard for me to believe you have been around since 2006 and have as many post as you do and yet it seems you know absolutely nothing about what it takes to build these motors.
This is not some stock rebuilt motor job that was thrown together in the shade of somebodies oak tree. This motor is proven, built by the best engine builder in our community (or at least he is the fastest and that alone is enough to take the title of the best let alone his obsession with perfection), and has the best possible parts money can buy. Not one penny was spared when putting this combo together, I should know, right Brett

Your little price quotes are just about f'n hilarious, $400 for a 109 block is about right, but guess what sparky, the fittings on this motor to make the external oiling system work will run that much alone. Guess what, we haven't even begun putting fuel fittings and sensors on the thing. And the heads on this motor, don't even get me started, holy moly the time effort and money put into perfecting the flow rates and oh btw that flow matched intake sitting there didn't come cheap either. Then to sit there and say it would only cost $2500 more to build a TA, damn dude that is insane. You obviously have never built a motor of this caliber or a TA for that matter. If so, it must have some really cheap parts on and around it, and that's kind of problem all to itself.
The kick in the nuts is that is only the motor, take a real hard look at the car and it is obvious the people putting it together not only knew what they were doing, but they also obviously had a serious eye for detail. The final product that Otto put out on this one is second to none with the best of everything.
