I was hoping you guys could give some good recommendations for a carb. The car is a 71 chevelle that will be a 90% strip car.
The motor is a 454 bored 60 over
10:1 forged pistons
Lunati 288/296 solid lifter cam
AFR 305 heads
Victor Jr intake
Electric fuel pump, fan, and water pump

The car has a turbo 400 tranny and 4.11 posi rearend.

What size and what brand of carb do you guys think would give me the best performance?

Demon 850 mechanical secondaries will work great with stall up to 3000. All demon carburetor have New Idle-EzeT Idle Speed Tuning System for camshafts, I think you will love it.

Holley- you know you can't go wrong with holley either!

I would go with the HP 1000. I have a very similar motor with a little bigger cam. My Vette went 123.6 mph the first time to the track in total street trim, full exhgaust etc. The 950 only wet flows 830 cfm.

Which is all he'll need unless he's taking it to 6800+ rpm.

Sounds like the Holly 950HP is the way to go! :D

Another question, what kind of et's do you guys think this combo will be able to turn once it's dialed in?

Maybe a little too much head :D I'm guessing mid 11's to low 12's...did I leave myself enough room to err graemlins/thumbsup.gif

Is there really such a thing as too much head?? :D

I was really hoping to get this combo into the 10's. 10.999 would be okay with me, I just want to run 10's!
