I think with E85 now available to most and considered street fuel it opened up the building of higher compression engines. I have no problem using an 8 inch converter in a street build and know many who run one. Caltracks and Micky Thompson street radials fix most traction issues. A .550-.620 roller cam would probably be my go to with a set of ported Speedmaster or Edelbrock heads flowing 285-300cfm in the usable lift range. Because of the high stall a ported Victor340 and a 750-850 Holley carb. Safely in around 11.5-1 compression and Scat rods. The smart build would probably have a 904 transmission and 4.10 gears. I’m not much of a windage tray guy but for a street build it would require a different type of pan than I am used to so more attention would be spent on drainback and windage issues. Standard oil pump gently massaged for a starting point.
