Air flow through hood scoop

Take the Turkey pan off and do the run again - if the carb is jetted properly, the plugs will read perfectly! We proved this out while tuning for a Run & Gun many years ago.

So you're saying if I'm running an 850cfm holley on a 427 so I should take the turkey pan off.

The turkey pan is killing your hp.

I did the cal's on an 8" S&S air filter on a 351W with 400 flywheel hp. At 4000 rpms it was losing 97 hp because of the filter.

use this link to cal your air filter. You can not get the proper size filter in the turkey pan.

Thanks Dwight. I've seen the TP setup before on a small block but thought it looked odd - and constricting on the 427.

We'll be installing the new Holley next weekend and I'm dropping the turkey pan. It's great to live 30 minutes from Summitt too!
