My 79 Ozzy Falcon has a 351 Cleveland (yes it is, there are heaps in Oz and NZ). The guy that dyno tuned it said "ya carb is worn out, dont rebuild it, throw it and buy a new one". It currently has a Holley 600 sq bore vac sec.
The thing is, i've done a few drags recently, the best being 15.8. Now i'm getting a bit less concerned with economy and more concerned with going faster.
Most people said "get a 650 DP". I would like to hear other opinions. But would prefer to stick with Holley.

Cheers
Phil
