OK, I did not know having a primary PV meant that much jet size. I just assmed that going down that far on the carb I have could create too lean of a condition @ 72. The Secondaries are like in the 80's (maybe 84/86) & it is a blocked PV w/ jet extensions. See again, I have more of a drag carb than a street carb. The question is how to make it run most efficent on low/mid for street & be able to do minor tuning & run decent times on the weekends. It is frustrating when I am still learning too. It would be nice to have a drag car & street car!! God bless, Scooter

I bought a 950 hp new back when they first came out and it was jetted 78 front and rear with two power valves...just an FYI.

If you have 86s in the rear the 76 you have would be close to being squared. I understood that you had 80s in the rear. Just remember the PV gives you 6 to 8 more jet sizes, in order to square the jets. Being a little lean on the street is good, mainly because your not going WOT that often. We usually jet down 2 sizes when racing 1/8 over 1/4 mile racing.

Copy that.

I forgot to mention that this car has a Dominator TeamG w/ a 4150 2" alumium riser as well which is angled/tilted to make the carb point down a little. I assume that everything should tune out the same as if it did not have the conversion/riser?? I assume this riser is for top-end??

Tod- I see there are 2 Quick Fuel 950's in my Summit book (both gas). One is about $100 more... I have the lesser expensive one (i think it was like $687 roughly. I forget the difference, but mine is stock that way w/ jet extensions & a secondary PV block. I like it for the extra adjustments (like the secondary butterfly) & the float windows etc....
