Hello All..........hey daigostang you will probably get some recommendations on going to a 650DP on your application........As long as ya have the 5 speed tranny I would reccommend a 650 DP also...........It just seems they work better and ya know when the secondarys are open........750 vacumes are great carbs also though..........I attatched a link below to my BIGS 650 Stage 3 carb ya can look at..........Thanx alot, Jesse
It's just math guys, take the inchs x the max rpm and divide it by 3456. and you have the max air your "pump" will move. For the street, add 50 to that number and you have the biggest carb you need. And be realistic, you can always lie to your buddy and tell him its an 850.
Anyhow, with that RPM window your looking at a 670 CFM carb for a really head snapping piece, something along the Holley Avenger line.
But if its race only, up to a 750 wont "kill" you, itll free the flow up for top end, and vacume signal wont hurt for street driving. If you really want to WOW em at the car show, get the baby dominator. THe lil 750 dominator would really aid in front runner fuel distrobution, and as Chris said, you could always fib and tell em its a 1050.
IF yuor determined to stay square bore bound then the lil 750HP is a nice setup. two circuite air bleed adjustability with 4 corner idle mixture adjustment. For economy you can stick with front and rear power valves and tune them for the driving you do, or block the secondary side with a Holly available plug and just jet for WOT fuel flow.
