I don't understand this..
"New six pack set up. Dyno last month @715 ft lb of torque."
Was the tune rich then? Doesn't your dyno guy tune the engine?
You still haven't answered how the engine is set-up and how you have the carbs now. I have found the 6-pack is just like any other carb'd car. You have to start from square one and go step by step. For your application, given the cubes I'd start out w/ 70 jets, 35 squirters, 6.5PV and maybe the plain springs. I'd turn the mixture screws in all the way in then back them out 1.25 turns. I turn the idle screw up to and start the car. I let it run at about 2200-2400rpm and set the total timing at 36* (don't forget to unhook the vac advance if you are running one) Then I'd turn the idle down to 900-1000 and adjust for best vacuum and check initial, it should be around 16-18*. Then you can go for a test drive. Check for flat spots, bogs and whatever else. Pay closer attention to how the car responds and no so much the a/f meter. Do that and get back with us.

the fuel pump he installed is the carter high volume. it has a fuel pressure rating at 8-9.5 psi. put in the regulator, get the pressure down to 4ish and then do the above.

Here is the best I can tell you from my mobile. Not at my shop where came data and such is. 543" stroker, ported Edelbrock heads, aggressive cam, long duration, roller cam, lifters, rockers, 10.8:1 compression. Bone ass stock 6 pack carbs. The carbs are at the Carb shop and should be done Tuesday. What he is doing is unknown. He says he does big stroke tri powers on a regular basis. He knows what works I guess. Dyno day was a fiasco. Pertronix distributor advance didn't work. Had to rush home 40 miles away to get my back up dist. High review did do 700-715 torque@ 34 to 36 degrees. Never had time to tune. Idled high . Was not ideal.

Was not ideal. Car still has the back up 440 source electronic distributor which works fine. Only reason I bought the Pertronix to begin with is the internal rev limiter. Timing is consistent and seems to be correct. All advance in by 3000. Vacuum at idle unknown today. Remember runs very rich with both sets of six pack carbs. The 2nd set is off my other Bee and that one runs great with them. ???? More info needed? Thanks.

I haven't run either but if I had to choose between the 2, I think I'd go w/ the MSD. That said there is no reason the 440 Source unit shouldn't work. You do understand that with your cubic inches and agressive cam that you will want a "locked" distributor mean it may have to be welded and all your timing should come in full at 2400. I think you should addres the fuel presure problem 1st. if you have too much pressure it will run like poo poo.

(again). one change at a time!

The 440 source distributor was a cheap out of the box dist. Nothing was set up. You mean changing the curve on it? Can you even do that with one of those? And has anyone had a positive experience with one of these or the MSD ready to run distributor. I have one of each.

My carbs will be back from the carb shop Wednesday am and Im going to use my new MSD ready to run distributor as well. I will add the Holley regulator as well and see what happens.
