Re: Packard Six with dual carbs?

For more power out of ANY engine usualy requires a "street grind" cam change along with some OEM carb jetting and or venturi changes and minor distributor advance changes to the oem distributor. But there in lies the problem: WHAT ARE THE SPECS for a street grind cam????? What did Edmunds et-all offer in a cam?????? At this point noone knows.

Even with all of those questions answered then any extra power obtained will probably be marginal. Maybe only 15% increase in HP at best.

Now if u want to spend months and many thousands of dollars on stroker billet crank shafts, special designed high compression pistons/combustion chamber reshaping, and cam grind experimenting which would require about two dozen cam variations then u can get significant power increase.

Looking for simple sunday after noon bolt on hotrod equipment won't get u much and in some cases NOTHING to less.


Quite ofen we will see "high performance" mods made to engines. Those mods may have been made for any variety of reasons NOT related to performance. I've changed to different carbs on a few engines that were "bigger' carbs but only because i couldn't get the OEM carb and had some misc junk laying around here i could modify slightly just to get the car running.
