Forget about what people think when they look. You've got a combination that is maintenance free and works to your satisfaction.

Your heads, cam and intake are basically as weak as OEM and will not support a 650 and you especially don't need a Speed demon.

"I like the idea of the Holley 82651 with mechanical secondaries and no choke.
Is that a good idea, if no why not? "

Forget mechanical secondaries because you have no capacity or velocity to handle an instantaneous throttle application. You need to co-ordinate the whole induction system-can't just bolt on racy eyewash and expect it to behave as it does now.

If you only change a carb put on a vac secondary 550 or 600 cfm 1850 Holley-but I believe the bolt pattern is different than your Ede and an adapter or mainfold change is necessary.


If you alter your present combo-do it all or forget about disappointing viewers-you will screw up a good thing and never stop playing with 'adjustments'.
