What's wrong with the unleaded VL 304 carby V8 ? They had big valves heads as standard & even with their lower compression ratio went harder than a stock VK V8. They had a Rochester & a HEI dissy, it was quite a good package.
The VL RB30-E was typically Japanese, beautifully built & good in early life but they didn't age too well, especially the electronics. I've now closed my workshop where I serviced & repaired 1,000s of VLs, & now I sell parts for them. Distributors (crank sensors), injectors, fuel regulators, idle motors, air flow meters, ECUs, etc. etc. all have a higher failure rate nowadays than their V6 equivalents, but they are good for business.
As Byron has said, they would have been useless in a commercial application, not enough torque.
