What's my junk worth? Options

[Franky_Four_Fingers]

Hoping I can tap into the collective knowledge here:

I bought a 1971 914 which was built and raced in CVAR about a year ago and would like to continue my plans to create a GT tribute. The car came with a fresh 1.7 which I'm told was enlarged to a 1.9. The transmission (side-shift) was rebuilt and modified to be "close ratio". There was also some top-end mods done in 2018 in an attempt to find more HP.

I will post what info I have below, but I'm hoping some of you might help me identify what I have and what it's worth. My other question is whether or not I should keep the modified transmission or run the stock rebuilt 901 that I have. I'm planning to install a 2.2 with moderate cams and carbs. TIA

Info from the build sheet:

Engine: New Weber 40 IDF’s / EMPI Manifolds & Linkage / New Distributor Cap / Coil / Wires / Points / Plugs / New Euro Racing Matched Length Headers and Megaphone Exhaust. Heads overhauled by HFM 9:1 compression cut, New Pushrod Tubes and Viton Seals. New SCAT Hi Capacity Oil Sump.
Transmission: Internals Rebuilt by Joe Cogbill: Close ratio 4/5 gears installed, all new syncros, diff seals and gaskets. Shift linkage re-bushed and adjusted.

In case anyone here knows the car, I will post a pic.
