Street Demon or Edelbrock AVS2 or ?
Had the 750 Street Demon w/composite body on a 410 that was under a doghouse engine cover so it was subjected to more extreme heat than the typical car engine bay. Never any fuel percolation/boiling/vapor lock etc issues driving it in stop and go, or after shutdown for periods and restarting. Ever. Works great. Being used on another car now. Also have the AVS2 625 on a 90 W-150 w/318. It too works great but after shutdown and restarts after a while has the typical delay in wanting to fire. It is mounted on the Edelbrock wood spacer to help with heat soak. But you still have to slowly press down on the throttle while cranking before it starts. Then you have to clean it out by giving a few revs and then it’s fine. Bought it for cheap so...Of the two the composite Street Demon wins out
