Guys i have a 615 inch chevy,11to1 compression sonnys 14.5 degree heads 877/875 on the cam it was built for a f3 and alcohol,the heads flowed 571 intake and 390 on the exhaust @900 I am going to just run it on motor and 2 stages this year,my question is im not sure what carb to use this year,i heard the king demon 1295 was good,im not sure what kind of power this motor is making its never been dynoed,anyone ever run a combo simmular to this and if so what kind of power did it make and what carb did you use,I was told that motor should be making 1000 hp because of the heads,, but im not sure i may just have it put on the dyno,thats the motor in my pic...

Same cubic inches as mine only you have more cylinder head but less compression and cam, I would say it will go 1000, What did Patrick suggest ?? He put one of his 1600's on mine for 1100 hp. and it was 28hp better than a borrowed but new 1250 from another shop.
