Not a Holley fan. I ran a 4160 R8007, 390 CFM four barrel on an Offy intake on my '68 C/10's 292 L6, with Clifford headers for 25 years. Every time it backfired, I had to replace the 8.5''Hg power valve. Then it had to be retuned. I always had to get a Holley expert to help. When I rebuilt another 292 in 2005, after the 500 mile break-in run, the Holley backfired, and wouldn't hold a tune. We suspected, after 250,000 miles, the plate surface was warped. It was cheaper and easier to go to a 500 CFM Edelbrock 1404.
The AFB design has no power valve. I can tune it myself.
