I ran one for years on a 71 340 it was great for low end but is short and small port so top end was realy lacking.
The same goes for performer intake both have smaller ports like a 318 head good for "street use" on 340-360
The engine I used it on was a Ford 400M and it just sang at 6000 rpm. It was tall enough that I had to use a scoop on my Torino with a drop base Moroso air cleaner. This is obviously an apples to oranges comparison though as I was using closed chamber Australian 351 Cleveland heads. These heads are splay valve and a "semi hemi" configuration and the ports/valves are huge compared to chevy or Mopar heads.
