Work on my 1972 350ci 200bhp small block convertable is finally progressing. I am now putting my engine back together following a bottom end rebuild.
The previous owner fitted a higher lift, but relatively mild, Summit 1102 cam. The car is fitted with the original Californian Qudrajet carburator but the airpump and all associted emissions hardware have previously been removed. I have been getting poor mpg and having difficulty setting up the carb. I am planning a new exhaust system, possibly with Summit long branch headers. I had a recent conversation with a fellow enthusist who advised the carb. was too restrictive & recommended I replace it with an Edelbrock or Holley 750cfm carb. I have read from another source that 600cfm is best for 350ci road engines, 750 would be too large. This book also recomended an Edelbrock manifold being "far supperior to the standard one".
If I can simply and relatively cheaply gain power, economy and efficiency through period upgrades then I would like to. I am sure there are many club members with tunning experience, could you please offer me your wisdom and is there anyone with suitable parts for sale?
