Thanks for the information gentlemen.
Fwiw, the dual quad setup was at the recommendation of Kenne-Bell who in fact recommended dual 750's, but I chose 500's as well as 9.0/1 CR mainly for running low or mid-octane gas on the street, but also at the nostalgia drags once in a while.
My aim was mid-range torque with an occasional run up to 5500 rpm.
Since the car is so light - 2300# sans top and 4-point roll bar, 2400# with - getting the maximum HP was not a necessity.
Just a moderate build did the trick and the car's run fine for 48,000 miles so far.
Reasonable gearing (3.70 diff) helps as well, but after Septembers street drags on Beale Street in Old Town Kingman, Arizona in September a 3.00 diff goes in for a little better gas mileage.
I've had four different cams and several intake setups on the car and have pretty much settled on the present combo with it's very mild cam (260 - 266 degrees advertised duration) and the Edelbrock Performer with Edelbrock 750 carb jetted/rodded for the altitude - 3300'.
Granted, not as many changes as you folks get into with dyno tuning et al, but enough to make it interesting.
Subjective, I know, but it seems the dual quads run a little harder than does the single 750.
Probably going to learn the truth no matter which way it goes after our local dragstrip goes in.
From a lot of the Buick oriented reading I've done, it looks like I'm on the right track with this particular combo.
I think too, using one of the bigger cams I have stored away for the 10/1 CR engine will work ok.
Trouble for most amateurs is they don't have a dyno and have to make reasonably good guesses right up front.
In any event, I enjoy this site greatly and like reading what David writes as well as what others have to say.
Thanks again.
