I am in the very early planning stages and collecting information on what the 360 build will cost. It will be a street only car. I was wondering what the difference was between the Edelbrock Performer and Thunder AVS carbs other than the ability to make easier adjustments on the Thunder? Which would be "better" for a street driven car? Finally, what type of horsepower can I expect from a 360 with stock ported heads, bigger than stock cam, aluminum intake/4-barrel headers, and other goodies you all are sure to recommend. Thanks in advance. Everyone on this forum has been a great help in getting me to think "realistically" if you know what I mean. :newb:
 
The main difference between the two carbs is the Thunder has a AVS style top cover. The secondary side is now tuneable via a locking spring on the side.
Since it is tuneable, IMO, you can end up seeing more torque as well as not getting that famous "dead spot" when you suddenly wack the GO pedal. The counter weighted air door of the AFB suddenly opens creating a lean moment.

I personaly do not see a difference that would leave me to believe there is a CFM difference.
 
Oh, power wise you could create 360 HP without ported heads and still use a small and streetae cam.

times two

the performer is an AFB and the thunder an AVS

i have and always will prefer the AVS over the AFB
 
I was going to go with the AFB so this was good advice for me to read. AVS is the one I will look into now. 360 hp from the 360 engine build I describe? That would be the ticket for me. This was really good news for me, thanks.
 
You could copy the first MoPar Performance create engine easy with a 9.0-1 ratio, 750 carb, stock heads with2.02/1.60 valves, headers. MoPar used there own purple cam at 284/.484 IIRC.
The heads were the 308's.
Use a RPM or Stealth intake
